    شهرداری ها به عنوان رکن اصلی مدیریت شهری در راستای ارایه مدیریتی پایدار و ساماندهی شهر، نیازمند درآمدهای پایدار هستند. وابستگی به درآمدهای غیرمستمر و ناپایدار شهرداری ها از جمله درآمد ساخت و ساز، نداشتن ضمانت اجرایی لازم برای کسب عوارض و درآمد های قانونی باعث ناپایداری در درآمدهای آنها شده است. سهم مالیات بر ارزش افزوده در درآمدهای شهرداری تهران حدود 20 درصد بوده است. بنابراین، مساله اصلی این پژوهش بررسی ساختار درآمدهای پایدار شهری و محاسبه مقدار درآمد مالیات بر ارزش افزوده از دست رفته شهرداری تهران به دلیل شکاف سیاستی (تعقیب اهداف خاص سیاستی دولت از طریق معافیت های مالیاتی، تعیین حد آستانه و اعتبار مالیاتی) و شکاف تمکین (اجتناب، فرار و تقلب مالیاتی) طی سال های اجرای قانون مالیات بر ارزش افزوده است. در این راستا، با استفاده از روش مکنزی (1991) و جدول داده- ستانده و بکارگیری داده های فعالیت های اقتصادی شهر تهران در نظام طبقه بندی بین المللی (ISIC)، شکاف مالیات بر ارزش افزوده محاسبه می شود. نتایج حاصل شده بیانگر این است که نسبت شکاف سیاستی به درآمد بالقوه مالیات بر ارزش افزوده در شهر تهران 7/51 درصد و نسبت شکاف تمکین 2/26 درصد بوده است. به عبارت دیگر، حدود 78 درصد از درآمد بالقوه مالیاتی در نتیجه شکاف سیاستی و تمکین وصول نشده است. بنابراین، رفع ابهامات و چالش های اجرای قانون مالیات بر ارزش افزوده و تکمیل احکام آن در زمینه ضمانت اجرا و روزآمدسازی مشمولین، فرآیندها، نرخ ها، معافیت ها، دامنه شمول و آستانه معافیت نقش مهمی در کاهش شکاف مالیات بر ارزش افزوده و افزایش درآمد پایدار دولت و شهرداری ها دارد.

    سیاست های متفاوت توسعه شهری منجر به نقش کنشگران مختلف در شکل دهی به مکان می شود و این امر نتایج متفاوتی در تولید مکان در پی خواهد داشت. درک این تفاوت و تاثیر آن بر محصول نهایی (شکل گیری مکان و از آن رهگذر حس دلبستگی مکانی میان ساکنین) هدف این پژوهش است. بر این اساس در این مقاله با بهره گیری از روش ترکیبی کیفی- کمی به بررسی میزان حس دلبستگی مکان (به عنوان شاخص اصلی در شکل گیری مکان) در محلات شهر اسلامشهر با خاستگاه های مختلف شکلگیری حاصل از نقش متفاوت کنشگران، پرداخته شده است. روش گردآوری داده ها در بخش بررسی میزان دلبستگی مکانی، پیمایش با استفاده از پرسشنامه و در بخش بررسی میزان نقش کنشگران، تحلیل اسناد و مصاحبه عمیق با مطلعین بوده است (رویکرد کیفی پژوهش). روش تحلیل داده ها بر مبنای بررسی معناداری اختلاف میانگین شاخص حس دلبستگی مکانی بین محلات دسته بندی شده در سه گونه مشارکت کنشگران است (رویکرد کمی پژوهش). این سه دسته عبارتند از: "ساخت به وسیله کنشگران با خاستگاه غیررسمی (مردم)"، "ساخت به وسیله کنشگران با خاستگاه رسمی (دولت)" و "ساخت به وسیله کنشگران با خاستگاه ترکیبی از کنشگران". نتایج نشان می دهد در محیط های شکل گرفته تحت تاثیر ترکیبی از کنشگران، حس دلبستگی مکانی بالاتر از محیط های شکل گرفته تحت تاثیر تنها کنشگران رسمی (دولت) یا غیررسمی (جامعه محلی) است. به عبارت دیگر می توان چنین نتیجه گرفت، کنش متقابل میان کنشگران و تامین شدن منافع کلیه گروه های ذی مدخل می تواند منجر به تبدیل فضا به مکانی دارای معنا برای ساکنین و از این رهگذر ارتقای حس دلبستگی مکانی آنان شود.

    Introduction Achieving the growth and development of society requires creating equal and contextual opportunities and how to use the talents and abilities in it. One of these opportunities is the possibility of the presence and mobility of the disabled people as other people in society; Undoubtedly, people with disabilities are part of the members of any society ,which, according to equality of citizenship rights, need to be present in urban public spaces and create social interactions; So, in this study, due to the importance of the subject, an attempt has been made to design and match this type of spaces in one of the most important and busiest boulevards of Semnan city (the area of Ghaem Boulevard as a readable urban public space) in order to solve problems, increase the presence and safe accessibility of the disabled people to these spaces that are the purpose of this research should be addressed because the city and its spaces are not just a system and physical or natural context, but also the context of human life and a place for the emergence of  people’s abilities and creativity, the realization of goals, and the search for their happiness and satisfaction.Materials and MethodsIn the present study, the type of study in terms of purpose is applied, and the research method in terms of nature is descriptive-analytical and field type. Library and documentary study methods have been used to collect information related to theoretical topics and explain the principles and criteria resulting from this section. The field study method has been used to recognize and investigate the current situation and analyze and evaluate the applicant’s spatial patterns in the study area (conduct practical studies). In collecting field information, methods such as observation, photography, and tools such as a researcher-made questionnaire were used. After analyzing the questionnaires and placing its findings in line with field observations and studies, using the QSPM method to analyze and prioritize the strategies obtained from the SWOT table and then according to the design indicators mentioned in the theoretical framework section, for each of the strategy extracted, executive solutions are expressed to design and adapt and solve problems in the study area and thus increase the presence of people with disabilities.FindingsThe findings of the present study show that in the design and adaptation of urban public spaces in Semnan, such as the area of Ghaem Boulevard, the conditions and needs of the disabled people, especially the physically disabled people, have not been paid much attention and these people in the study area of this research due to many physical problems have many issues and concerns, including lack of easy commuting on sidewalks and streets, lack of ease of access and proper use of public places, spaces and special arrangements for spending leisure time. All these factors have created a disorderly, unhealthy, unsafe, and uncomfortable environment for the presence and efficient use of the disabled people in this area, despite its potential. So, these people rarely enter urban spaces alone. Most of them, due to the lack of suitable conditions for the presence and performance of optional activities, prefer to eliminate this type of activity. They only refer to the area and use it to perform their necessary and obligatory activities.ConclusionBased on the results, it was found that our cities today, due to social, managerial, and physical defects, have spaces for the presence of healthy and capable groups and do not accept the reality of people with disabilities, both physically and socially, and have many issues and problems in various fields. Disabled people in these spaces, despite the existence of laws that claim equal citizenship rights with other members of society, in practice due to corrupt and inappropriate designs and far from the minimum standards,  and the lack of executive guarantee of regulations to create appropriate spaces, they are deprived of being present in the community and having safe and easy access to the public spaces of the city and using the facilities available in it and participating in various activities. Thus, principled design and adaptation and compliance with standards, especially in public spaces used by different groups, is the right of all citizens and requires a comprehensive and binding approach. Also, the results of the present study show that by implementing the following strategies, we can help increase the Presence of citizens, especially the physically disabled people. Solutions include adapting sidewalks, streets, public buildings, and urban furniture elements, revising and adapting the case study based on design indicators and urban planning criteria, and providing the conditions in which all people can use these spaces according to their citizenship rights because the adaptation of urban spaces as a physical context for all people to have equal opportunities to move around the city, access to all urban spaces and perform activities in various fields is a necessity for growth and development between human being and the surrounding spaces and in the whole society. Based on this, it can be said that a society whose development orientation (planning, management, design, etc.) is according to the conditions of all people and responds to their needs and problems is a society in which everyone will have comfortable living conditions and will benefit from it

    Introduction

     Smart cities provide better transportation and ease of access, improved social services, urban sustainability, and a better quality of life for their residents. Like most big cities in the world, Tabriz city faces complex problems in the field of population density, air, and noise pollution, providing transportation services, and social and economical housing. Therefore, the formation of a smart city based on smart criteria in the city of Tabriz based on big data can be a great help for the government and city managers in determining the smart city strategy. The reason for the lack of success in the implementation of the smart city is the need for more awareness of the smart city and its management and the effective factors in its formation. Therefore, it is very necessary and vital to identify the effective factors in the formation of the smart city of Tabriz at this time. The purpose of this study is to identify the living conditions in a smart city and its characteristics through the perception of residents (young people) of Tabriz based on a developed model. The criteria for choosing the city's young class is because young people play a critical role in the future of society, they play a major role in the process of creating a more stable and resilient city, and information and communication technology (ITC), which allows communities to adapt to the conditions that have arisen, grown and developed even when faced with difficulties.

    Materials and Methods

    The work method is quantitative-qualitative and includes two parts. A survey was conducted based on the theoretical aspects obtained in the review stage of the theoretical foundations and background of the research. The second was based on field studies using a researcher-made questionnaire. In the questionnaire, a five-point Likert spectrum scale was used according to the level of agreement or disagreement of the respondents (1 completely disagree; 5 completely agree), which were part of the structure of the theoretical model. Therefore, to ensure the achievement of a high-quality field to achieve the goals proposed in this study, a systematic literature review method was used, a well-known scientific research method that has been accepted by researchers in various fields. It is a research strategy that defines, from selection to analysis, all the steps necessary to conduct a reliable and accurate bibliographic review. In this research, the articles from authoritative databases were examined. According to these selected articles, the articles that did not belong to scientific journals were excluded. Therefore, after identifying the gap in the theoretical framework and considering the studies conducted on all aspects of the smart city, a study Exploration was conducted through the development of a bibliographic review with a qualitative approach as well as field research with a quantitative approach. The statistical population of the research includes the population of Tabriz city, 1593373 people. The sample size was 384 people based on Cochran's formula. A confirmatory factor analysis (CFA) and a multi-group confirmatory factor analysis (MGCFA) were chosen for the quantitative analysis. Then, a correlation matrix was used using Partial Least Square Structural Equation Modeling (PLS-SEM), and its data was analyzed by Smart PLS software. Microsoft Excel and IBM SPSS software were also used for descriptive analysis.

    Findings

    The results of significant path analysis showed that all hypotheses are confirmed, as there was no significant difference between the main sample and the sub-samples produced by the statistical technique with critical limits for the t-Student test. When the operational definitions of "characteristics of smart cities" were analyzed, the path analysis of "characteristics of smart cities and the environment" was accepted with the highest β in both samples: the first sample (β=0.822) and the second example (β=0.793). This relationship is related to using information and communication technology to better protect and manage environmental resources and related infrastructure and to create more sustainability. In this context, the technologies developed in the city of Tabriz are considered factors that drive the efficiency of the city and enable the optimal use of resources and reduce environmental impacts, for example, by improving air quality. Citizens of a large metropolis like Tabriz (based on the selected sample) face daily problems such as roadblocks, poor public services, and poor sanitation, as well as air, water, and street pollution, which create disturbances and concerns that require practical solutions. On the other hand, according to the operational settings of smart city features in Tabriz city, the relationship between smart city path analysis features and the economy was the relationship that had the lowest value among all relationships in both sample 1 (0.627) and sample 2 (0.556) and confirmed that the smart city is an innovative urban ecosystem that is characterized by the extensive use of information and communication technology in the management of its resources and structure. However, it is necessary to broaden the concept of the economy with access and information to the people who participated in this survey so that they can be more active in issues related to the spirit of innovation, entrepreneurship, productivity, labor market, international integration,  and ability to change the company. Moreover,  a critical aspect of this structure is related to competition, so it is necessary to invest in the creation of these innovative environments (for example, rooms or co-working spaces) so that one can strengthen the interaction with young people. The results showed that in this model, it was possible to adapt all the features of smart cities. The characteristic of the environment was the case that showed the most relationship in contributing to city efficiency and reducing environmental effects on the quality of cities, and the characteristic of the economy was the case that showed the least relationship.

    Conclusion

    Finally, it is argued that overall efficiency in all features depends on citizen engagement in public life innovation processes. The smart city is different and useful from other solutions due to its success in the field of innovation, basically depending on the collaborative process that encourages the discovery and creation of ideas in developed environments.

    Introduction

    The tourism industry, playing an influential role in the economic processes of countries in the case of development and sustainability, has positive effects such as job creation, income generation, circulation, and foreign exchange attraction through domestic and foreign visitors, which can be mentioned as its power to generate income as the third industry in the world after the oil industry and automobile industry. Increasing stable and appropriate income is one of the economic effects of this industry, so the share of gross domestic income of countries from tourism reaches more than ten percent. Tourism is one of the critical economic pillars in many cities, which plays a vital role in creating and earning a stable income, employment, infrastructure protection, and increasing the quality of urban public services. Therefore, it causes the mobility of the urban economy and its correct movement in the path of sustainable development. East Azarbaijan province, centered on Tabriz, by registering more than 1800 works registered in the cultural sectors and tourist attractions in the UNESCO list, has made this province rank in the fifth rank of provinces with tourism potential in Iran. The city of Tabriz has been called one of the country's seven cultural and historical cities, according to the official documents and recorded cultural records. Tabriz has a high potential for tourism development due to its location on four transportation routes and the presence of numerous valuable cultural and historical attractions. Economic activities in this city are concentrated in the sectors of heavy and light manufacturing industries, food industries, crafts and arts, trade and services, and tourism, so Tabriz is the headquarters of four brands out of 100 prestigious brands in Iran. The presence of numerous historical, cultural, and artistic buildings with a long history has made the metropolis of Tabriz capable of developing and attracting tourists from neighboring cities and provinces, tourists from other parts of the country, and tourists from abroad in terms of tourism.

    Materials and Methods

    The current research is of an applied and survey nature. Moreover, the current research is descriptive-analytical. Library and field methods have been used to collect data. In this research, a questionnaire was used as a data collection tool. The statistical population of this research includes two categories of managers (Cultural Heritage and Tourism Organization managers and Tabriz Municipality managers) and tourism industry stakeholders (hoteliers and companies active in the field of travel services). Therefore, in this research, by default, 60 questionnaires have been considered for each group of the statistical population and a total of 120 questionnaires. In order to analyze the data, descriptive and inferential statistical methods were used in the SPSS 25 environment. Means, frequency tables, frequency percentages, and graphs were used in descriptive statistical methods, and Pearson's correlation coefficient, regression test, and SWOT analytical model were used in inferential statistical methods. In order to check the validity (reliability) of the measurement tool of the current research, it has been accompanied by the guidance of university professors and related managers to determine how well the questions represent the content and objectives of the research; Content and form validity methods and techniques have been used. Cronbach's alpha coefficient was also used to measure the reliability of the research questionnaire. In such a way that according to each variable, the questionnaire was given to the professors and experts of the mentioned field, and it was calculated in SPSS software; Cronbach's alpha coefficient for each economic, managerial, infrastructure, and policy variable, respectively, 0.938, 0.911, 857. and 0.887 was obtained.

    Findings

    The analysis of the data obtained from the descriptive statistics shows that the average of the economic variable among the sample is 3.05, the average of the managerial variable is 3.52, and the average of the infrastructure variable is 3.31. The average of the policy variable is 3.22. In the inferential statistics section, Pearson's correlation test was used to discover the relationship between economic stability and municipal and citizen incomes with tourism development. According to these tests, the Sig(significance level) is 0.000, and since this figure is smaller than the desired alpha (0.05) with a confidence interval of 0.95, the relevant variables are linearly dependent, and the relationship between these two variables is confirmed. The correlation coefficient is 0.713, which shows a high correlation. Therefore, it can be concluded that the development of tourism has a positive, significant, and direct effect on the stability of the economy and the incomes of the municipality and citizens of the metropolis of Tabriz. Regression variance analysis or ANOVA also confirms the linearity of the relationship between the two variables of tourism development and economic stability and income in the municipality and citizenship of Tabriz metropolis because Sig is less than 5%. The results of the regression analysis show that for each unit of change in the independent variable, 0.71 changes in the dependent variable; It means that by changing each unit in the development of tourism with 0.71 certainties, it can be said that it can be changed in the dependent variable or economic stability and municipal income and citizenship. Also, the results showed that the total sum of strengths and opportunities, with an average of 3.2,2, is superior to the total sum of weaknesses and threats, with a total average of 2.5. Also, according to the evaluation matrix of internal and external factors, since the final score of the evaluation of internal factors (IFE) is 22.3, which is the final profile of the review of external factors (EFE) is 2.5, the type of aggressive strategy is superior to other strategies. Since offensive strategy is a combination of strengths and opportunities, strengths and opportunities are superior to weaknesses and threats.

    Conclusion

    Today, the sustainability of the urban economy is not a need. Still, as a leading necessity in the sustainability of the urban system, it has been noticed by experts and urban managers, and in this context, the tourism industry as a solution to stimulate and facilitate growth and development, with a long-term perspective in the program. Urban planning can lead societies toward sustainable development. The present study was conducted to analyze the effects of urban tourism development on the stability of the economy and the income of the municipality and citizens in Tabriz city. The results of the surveys showed that the development of tourism has a positive, significant, and direct effect on the stability of the economy and the incomes of the municipality and the citizens of the metropolis of Tabriz. Finally, by assessing the results of the SWOT analysis, it was determined that the most suitable strategy for developing tourism in the metropolis of Tabriz is an aggressive strategy. Therefore, by considering the above and the need to pay attention to it in the planning of tourism development in Tabriz city, we can hope for an increase in the income of the municipality and citizens and the stability of the Tabriz metropolis economy. Planning for the sustainable development of tourism and identifying the strengths and weaknesses, potentials and limitations should be in line with the plans and goals of the managers and other guardians of tourism in this region. In general, the current research can be the basis of macro-scale evaluation.

    Introduction

    The sense of attachment to a place is one of the most important components of quality in urban spaces, which has semantic, emotional, and functional factors. This feeling takes place after understanding and judging the environment. In the case of satisfaction, it causes the optimal use of the environment and ultimately causes the continuation of the presence of individuals. In the evaluation and experiences of the implementation of urban development projects in the world and especially in our country, it has been proven that these projects have had little success in creating a qualified urban environment. In this regard, a new approach to preparing urban development plans with an approach to the city and an integrated vision called design-oriented planning has been proposed, which is a general process to connect planning to design. This topic is a product-oriented design that pays attention to all dimensions: physical, economic, social, psychological, perceptual, and visual. As one of the five cities around Tehran, Parand city is of special importance due to its location and characteristics.   Its special place is due to its special place to organize the population and the activity of the urban complex in the master plan and the plan of the urban complex of Tehran, i.e., the plans beyond it. Moreover, Parand city has a special regional location, which is strategic in terms of location. This research seeks the question of how design-based planning as an approach to improve the quality of the urban environment can be used to formulate a model to improve the sense of attachment to the place as one of the most important components of quality in Parand city. The key goal of this research in this direction is to determine the criteria for improving the sense of attachment to the place as an important dimension in improving the quality of urban life, emphasizing the Design-Led planning approach in Parand city.

    Materials and Methods

    In this research, according to the purpose and nature of the research, the combined or mixed exploratory research method has been used. In the first stage, the theoretical foundations, studies, and background related to the sense of attachment to place and design-oriented planning were analyzed and compiled systematically. In order to ensure the validity of the qualitative part, the opinions of professors and scientific experts and the theory of experts were used. The inductive content analysis method was used to analyze qualitative data. Therefore, in this section, with the help of open, central, and selective coding, the content categories in the studied model that was available in the literature and documents of the research subject have been searched, and finally, after coding, the research analysis model has been presented. In the second step, in the quantitative method, the questionnaire was made from qualitative data, and the face and content validity of the questionnaire was confirmed by experts, supervisors, and consultants. Kolmogorov-Smirnov tests, regression, and correlation tests were also used to analyze the data.

    Findings

    Based on the obtained results, it is determined that according to the conceptual model of the research, there is a significant relationship between all the variables of the research. In other words, there is a kind of convergence between the design and the planning criteria of the design-oriented planning variable and the criteria of place dependence and place identity variables of place attachment, that is, by promoting the criteria of place identity, place dependence, design-oriented planning, one can feel an attachment to Improve the location.Furthermore, the effect of place identity, place dependence, and design-oriented planning in order to promote place attachment is positive and meaningful.

    Conclusion 

    In this regard, the sense of attachment to the place was considered as a central category, and three factors of place identity, dependence on the place, and design-oriented planning (as an influential element and innovation in research) were identified as elements influencing the sense of attachment to the place. According to the findings of this research and the conceptual model of the research, there is a positive and significant correlation between all research variables, in other words, between the design and the planning factors, the design-oriented planning variable, and the criteria of place dependence and place identity, the variable of attachment to a certain place. There is convergence, that is, by improving the criteria of place identity, place dependence, and design-oriented planning, the sense of attachment to place can be improved in Parand city. In examining the authenticity of the claim of the existence of the effect of place identity, place dependence, design-oriented planning, and design factors in the second phase of Parand city on promoting the sense of attachment, since their significance level is less than 5%, their effect is accepted in the direction of promoting attachment to the place. Considering the background of the research and examining the results of the current research with recent research, it can be acknowledged that the missing element in recent research is the role of the design-oriented planning approach in promoting the sense of attachment to the place because in the evaluation and experiences of the implementation of the project Urban development projects in the world and especially in our country have proven that urban development projects have had little success in creating a quality urban environment. Therefore, various urban thinkers have supported the presence of quality-oriented thinking specific to urban design in all scales (macro and micro) of urban development plans to create a quality environment, and thus a new approach in preparing urban development plans with a visionary approach to the city. They were integrated into the name of design-oriented planning. In this research, the role of this factor was investigated by identifying the relevant indicators that can be of great help to urban designers.

    Introduction 

    Municipalities, as the main pillar of urban management, need sustainable revenues to provide sustainable management and organize the city. Dependence on non-continuous and unstable revenues of municipalities, including construction income and lack of executive guarantee necessary to obtain tolls and legal revenue, have caused instability in their revenues. Finally, it is possible to amend the relevant law in the following periods by recognizing the jurisdictional and subject defects and guaranteeing the implementation of the value-added tax law and the methods of solving them. This will reduce the conflicts between the tax affairs organization and the municipalities. The share of Value-Added Tax in the revenue sources of Tehran Municipality has been about 20%. So, the main problem of this research is to investigate the structure of sustainable urban revenues and calculate the amount of lost VAT revenue of Tehran Municipality due to the policy gap (pursuing specific government policy goals through tax exemptions, setting the threshold and tax credit) and the compliance gap (tax avoidance, evasion, and fraud), during the years of implementation of the VAT law.

    Materials and Methods

    The VAT gap is calculated using Mackenzie’s (1991) method and Input-Output Table and applying data on economic activities in Tehran in the International Classification System (ISIC. The first step in calculating the tax gap is to calculate the potential capacity of value-added tax based on consumption, where investment expenses and export of goods and services are deducted from the tax base, and the import of goods and services is added to the value-added tax base. Moreover, in calculating the legal tax base, the value of tax-exempt goods and services is deducted from the potential base, and the amount of double taxation during the production-distribution chain is added to the tax base.

    Findings

    Based on the calculations made in 2017, the potential revenue from VAT was equal to 24 thousand billion tomans, of which the government’s share was 16 thousand billion tomans, and the share of Tehran Municipality was 8 thousand billion tomans. Additionally, the value-added tax gap was equal to 18.8 thousand billion tomans, of which 12.4 thousand billion tomans was the policy gap and 6.3 thousand billion tomans were the compliance gap. The government’s share of the policy gap was 8.3 thousand billion tomans, and the share of Tehran municipality was 4.1 thousand billion tomans. The government’s share of the compliance gap was 4.2 thousand billion tomans, and the share of Tehran Municipality was 2.1 thousand billion tomans.
    The results show that the ratio of policy gap to potential VAT in Tehran was 51.7%, and the ratio of compliance gap was 26.2%. In other words, about 78 percent of potential tax revenue has yet to be received as a result of the policy and compliance gap. Therefore, clearing up the ambiguities and challenges of implementing the VAT law and completing its provisions in the field of guaranteeing the implementation and updating of beneficiaries, processes, rates, exemptions, scope, and threshold of exemption play an essential role in reducing the VAT gap and increase the sustainable income of the government and municipalities.

    Conclusion

    In recent decades, unstable incomes have been one of the most critical measurements of municipalities’ income, which is obtained from ways such as the sale of density and the issuance of building permits. This factor causes stagnation in the budget deficit of municipalities during fluctuations in the economy, which has caused many problems for the cities of our country. Value-added tax as a sustainable income of municipalities has had a share of 20% of Tehran municipality’s revenue resources. Still, its implementation has had flaws in jurisdictional, subject, and enforcement areas. Based on this, articles 123 and 138 specify the method of distribution of tolls. However, the basic issue, which is the guarantee of the collection of tolls, is still uncertain. Regarding the issue of guaranteeing the collection of tolls by municipalities and the necessity of strengthening the fields of local tolls and related foundations and innovative categories in this field with the approach of income stabilization, the bill under consideration in the parliament lacks a reliable ruling. What has been seen from the latest amendments and omissions of the plan due to the objections of the Guardian Council and the views of the commission in the Islamic Council is far from the strategies contained in Article 174 of the Fifth Development Plan Law and other requirements for stabilizing municipal income.In this research, the potential value-added tax capacity of the Tehran government and municipality has been calculated using the data-output table, and by deducting the exemptions and adding the effect of the tax cascade, the legal base of the valuadded tax has been calculated. Finally, by calculating the potential and legal income of value-added tax, the policy gap and the gap of non-compliance caused by the application of the value-added tax system have been calculated based on the share of Tehran Municipality and the government. The obtained results indicate that the ratio of policy gap and compliance of value-added tax to the potential base of value-added tax in Tehran city was 53% and 27%, respectively. In other words, about 80% of the potential tax capacity has yet to be collected.Considering the flaws in the areas of competence, subject matter, and the guarantee of the implementation of the value-added tax law, in this research, it is suggested that by removing the flaws in the implementation of the value-added tax law and completing its provisions in the field of guaranteeing the implementation and updating the subjects, processes, rates, Exemptions, the scope of inclusion and the threshold of exemption, important steps to be taken in order to strengthen the fields of local taxes and related foundations and innovative categories in this field with the approach of stabilizing incomes and reducing the tax gap and increasing the sustainable income of the government and municipalities.

    Introduction

    Tehran is not a suitable place for pedestrians today. Air pollution and rising temperatures are the most important issues that cause this. Considering the existing density in urban spaces, one of the solutions that don't occupy the land area while having plants and enjoying their benefits is vertical and horizontal green surfaces or in other words, green walls and roofs.Therefore, this study aimed to investigate the effect of the urban green wall on air pollution and temperature. In this study, the Hedera helix plant of the green wall of Tehran Tabiat Bridge has been selected for further analysis of the subject. What will be investigated in this research is the effect of urban green walls on two factors including temperature and air pollution. Considering that the increase in air pollution can be a significant factor in creating global warming, and the temperature rise also leads to an increase in the number of secondary pollutants, these two parameters directly affect each other. Hence the difference between this research and the previous studies is that both of mentioned factors are questioned here. Furthermore, another difference is that most of the past research had examined urban walls in direct connection with the pollution caused by street traffic; however, in this research, the green wall of Tabiat Bridge, which is located at a height of almost 40 meters with markable distance from streets and pollutants such as cars, has been investigated. Therefore, the hypothesis of this research has been questioned in two phases. This hypothesis can be expressed in the form of this statement that the use of creeping plants including Hedera helix in urban green walls has an effective role in reducing air pollution and adjusting air temperature in hot seasons. This research aims to answer these questions, how much do plants growing in urban green walls reduce pollution and air temperature? According to the types of these plants, how far from the green wall this reduction may happen, and to what extent is it effective?

    Materials and Methods

    In two phases, this study measured the extent and effect of the green wall on temperature changes and pollutants in the air. In the first phase, temperature changes were measured by four data loggers simultaneously at distances of 0, 0.5, 1, and 2 (points A, B, C, and D respectively) from the green wall and a height of 1.5 meters from the bottom of the bridge. Field harvesting was done in three days of the summer season (July 5 to 8) from 10:00 to 14:00. (The average temperature in these three days is listed each half hour in the graphs.). According to previous research results, the green wall's temperature effects happen regardless of the type of plant. Therefore, this phase of the study was carried out regardless of the type of hedera helix. The second phase was done by sampling the plants on the wall, checking the amount of sulfate and nitrate pollutants in it, and comparing this amount with the values ​​of previous research. The reason for choosing these two pollutants in this research is the predominant volume of these two pollutants caused by the traffic of cars in polluted urban air. In the sample studied in this research, there are two types of Gracilis and Pedata Hedera helix plants, and in addition to the total absorption of the pollutant by the plant, the amount of absorption of these two species has also been compared with each other.

    Findings

    The results of this study indicate the effect of Hedera helix plant on temperature reduction. In hot seasons, it is effective only about 0.5 meters from its wall and it is not effective in further points. At best, the effect of temperature reduction of this wall occurred at point A with a distance of zero from the wall, about 0.8 °C, in comparison to points C and D with temperatures close to the outside air. The results of the second phase show that in the hooded Hedera helix type, the absorption rate of sulfate is 2 times and nitrate absorption is about 1.2 times more than the green type. To determine the amount of air quality, the more pollutants plants have absorbed, the more effective they will be in improving air quality by reducing pollutants. Therefore, in this research, it was shown that Pedata Hedera helix works more effectively than Gracilis Hedera helix to reduce air pollution.

    Conclusion

    Based on the results of this research, creating green walls using cheap plants, compatible with Tehran's climate and with rapid capital growth in Tehran can be used as an effective solution to absorb pollution caused by urban traffic and vehicle fuel. Furthermore, a comparison of two samples of the bridge and urban sample indicates an 18 times increase in sulfate concentration and 6.8 times in the nitrate concentration in the urban sample compared to Tabiat bridge. As a result of analyzing and comparing the example of the green wall of Tabiat bridge with other urban green walls, it can be concluded that being away from the polluting source as well as creating a covered space in order to control the radiation factor increases the efficiency and effectiveness of these green walls.  In addition to reducing pollutants, the effect of green surfaces in temperature adjustment is a very key factor. Although the effect of these walls in temperature reduction just happens in the close spaces near the wall, taking into account that the use of these green systems can happen on an extended scale the result will be remarkable. Considering the pollution conditions of cities today and proving the effectiveness of green walls in solving this problem, this issue will continue to be very important in creating sustainable cities in future research. Among the proposed topics, we can mention the effect of different implementation methods and the type of climbing plants or implementation system used in the green wall, and their efficiency and effectiveness.

    Introduction

    With the beginning of the land reform program in 1963 and with the collapse of the feudal system, a large wave of new population and labor force applying for land and housing went to the cities. As a result, construction activities and related economic activities intensified. The land, in economic activities, is sometimes produced as input and sometimes as a durable commodity. It creates attractiveness for people, and the demand for it increases in inflationary conditions. In these conditions, with the increase in demand, housing prices increase. Micro and macro factors that are effective in determining housing prices can be divided into two categories of external stimuli, such as the increase in the volume of money and liquidity, inflation, capital market, stock market, and in general, the factors that are rooted in macroeconomic and political activities. Internal drivers can be referred to as the price of land, the price of consumables, branches, and the cost of wages. In the neoclassical approach, land as an attractive input needs mechanisms to coordinate it according to demand and add to its capital value. According to economists such as Lancaster, Muth, and Rosen, the characteristics of goods are significant for consumers, and what is desirable for them is the quality of the product.

    Materials and Methods

    Considering the nature of the subject, the present research is of an applied type with a descriptive-analytical approach. The data collection tool was based on library and survey methods. Library studies were used to formulate theoretical foundations and background and identify research variables. In the next step, real estate consultants in Tehran Municipality’s Region five were questioned by the survey method using a researcher-made questionnaire. Then, the factors that affected housing prices in the study area during 2011-2021 were investigated. A multivariate regression analysis method was used using the Hedonic function to analyze the correlation between the variables. Furthermore, SPSS and EV
    views 10 were used to analyze the data.

    Results

    The analysis of the factors affecting housing prices in the Tehran Region five showed that out of 33 variables in structural, accessibility, and environmental dimensions, the coefficients of 28 variables were significant at the error level of 0.5. Among the physical variables affecting the price of housing, the floor area at 0.193, the building age at 0.166, the selection of suitable materials at 0.151, the location of the unit on the floors, especially the middle ones at 0.143, and the possibility of direct lighting (being towards the north or south direction of the housing) at 0.125 had a positive and significant effect on the housing price; for one unit of change in the mentioned variables, the housing price is increased. Among the accessibility variables, the distance between residential units to the nearest park and green space, that of residential units to the nearest educational centers, and that of residential units to the nearest public transportation station (metro, BRT, bus station, or taxi station) (-0.143, -0.124, -0.106, respectively) had a negative and significant effect on housing prices. The distance between residential units from the mentioned variables was effective in reducing housing prices. Among the environmental variables, the distance from narrow streets (-0.095) and the increase in traffic level (-0.087) decreased the housing price. Based on the one-sample t-test results, physical and structural indicators were the most important factors influencing the increase in housing prices, and accessibility and environmental components affected increasing housing prices, respectively. Pearson's parametric test results indicated a positive or direct correlation between structural indicators and housing prices. The coefficients obtained from this test showed that the correlation in structural, accessibility, and environmental indices were 0.659, 0.487, and 0.441, respectively. Moreover, the intensity of the influence of indices on housing prices using multivariable regression was (0.757).

    Conclusion

    Providing housing at a reasonable price is always considered a fundamental necessity in urban housing planning. From the point of view of microeconomics, housing is an immovable commodity, heterogeneous and dependent on a specific location, which, compared to others, is affected by various structural, spatial, and human variables in its valuation. This research analyzed the factors affecting housing prices in the Tehran Region five and indicated the way the micro factors increase housing prices. The hedonic function of housing for Tehran Region five was divided into structural, accessibility, and environmental dimensions to achieve the research goal. The results showed that among the mentioned components, the floor area, the year of construction, the materials of the housing, the location of the unit on the floors and the north-south direction of the housing, the distance of the residential units to the nearest park and green space, that of the residential units to the nearest educational center, that of residential units to the nearest public transportation station, alley and street width, and alley and street traffic conditions were significant variables in housing prices. The correlation test results showed a positive correlation between structural, accessibility, and environmental components on housing prices. In examining the rates of coefficients according to the regression test, it was found that the structural, accessibility, and environmental indicators directly influenced the housing price. Identifying the dimensions affecting housing prices can play a vital role in predicting and controlling housing prices, checking the quality of construction and living environment, and consumer preferences.

    Introduction

    Since the late 50s, the construction of megamalls has become popular in cities. Megamalls in different cities respond to the material and social needs of citizens, and in addition to meeting the needs of citizens, they also affect the area around them and cause changes in the price of land, the pattern of activities, and uses. The intensity of these effects can be different in different parts of the city according to their characteristics. In recent years, in the metropolis of Tabriz, various steps have been made in different parts of the city. For this purpose, in the present research, to investigate the aforementioned issue, three megamalls in different parts of Tabriz city have been selected and their effects have been measured. Therefore, the main question of the research is "how do the megamalls of Tabriz city affect their surroundings?" To answer the main question of the research, first, by using the techniques of a linear trend, Moran and Kriging, different parts of Tabriz city were categorized in terms of land price (valuable, relatively valuable, relatively low valuable, and low valuable). Then the location of each of the megaprojects is determined on the Moran and Kriging maps. Finally, to assess the effects of each of the samples on their surrounding area we applied the residential land price variable, control-intervention techniques, and trend analysis.

    Materials and Methods

    This research is quantitative and has a comparative-hypothetical approach. Megamalls have a significant impact on the spatial evolution of the surrounding area. In this research, the land price variable has been used to measure the effect of these properties on the surrounding area in different spatial value areas. According to the general trend of the research, first by using the techniques of linear trend analysis, Moran and Kriging in GIS software, the change in the trend of land prices in the city of Tabriz and the classification of different parts of Tabriz in terms of spatial value (valuable, relatively valuable, relatively low value and low value) were identified. In the second part of the article, the location of each of the goods was precisely determined on the Kriging and Moran maps. Moreover, to assess the effects of each of the samples on their surrounding area regarding the variable price of residential land during the years 2004 to 2021, control intervention and trend analysis techniques were applied.

    Findings

    According to the analysis, the price of land in the east of Tabriz city has the highest value and, it has the lowest value in the west and northwest. Further, according to the analysis of the linear trend of land prices for the intervention and control areas of megamalls, it was proved that the construction of three megamalls had a positive effect on the increase in land prices. However, the intensity of these effects was different in the surrounding areas as Laleh Park has made its surrounding lands relatively valuable and has an effective role in the price growth compared to Star Baran and Ipak Palace. On the other hand, Setareh Baran, which is built on more valuable land than Ipak Palace, has a greater impact on the value of its surrounding land than Ipak Palace. It should be noted that the slope of land value increase in the intervention areas is higher than in the control areas.

    Conclusion

    The main goal of the research was to investigate the effect of megamalls on their surrounding area. For this purpose, first, the price of land in Tabriz city was investigated from the years 2004 to 2021. Then, according to the techniques of a linear trend, Moran, and Kriging, price classification was analyzed in the city of Tabriz. According to the analysis, the price of land in the east of Tabriz city has the highest value and, in the west and northwest, it has the lowest value. According to the analysis of the linear trend of land prices for the intervention and control areas of megamalls, it was proved that the construction of three megamalls had a positive effect on the increase in land prices, but the intensity of these effects was different on the surrounding areas so that Laleh Park on the lands It is made relatively valuable and has an effective role in the price growth of its range compared to Star Baran and Ipak Palace. On the other hand, Setareh Baran, which is built on more valuable land than Ipak Palace, has a greater impact on the value of its surrounding land than Ipak Palace. It should be noted that the slope of land value increase in the intervention areas is higher than in the control areas. As a result, it can be acknowledged that the megamalls built in the valuable parts of the city have a greater impact on their surrounding area than the megamalls built in the less valuable parts of the city.

    Introduction

    Governance can be seen as an action, method, or system of administration in which the boundaries between organizations and the public and private sectors fade into each other's shadows. The essence of governance refers to the existence of interactive relationships between and within the government and non-government forces. Good urban governance is considered one of the four features of sustainable development and one of its tools, which has been mentioned in the development literature since the 1980s. Urban governance is a multilateral process between the official actors of the city administration on the one hand, as well as the activists of the civil arena as informal actors whose multifaceted interactions can lead to the compatibility of various interests among the actors. What is evident in this concept is the entry of civil society and the private sector into the process of planning and managing (urban) affairs. This is despite the fact that the government is a set of official and legal institutions with legal power. (Smart) cities need a proper governance system to connect all forces at work, enable knowledge transfer, and facilitate decision-making to maximize their socioeconomic and environmental performance. Therefore, we conclude that smart city governance is a style of management that is formed based on the intelligent participation of citizens through information and communication technologies. Smart city governance is a style of management that is formed based on the intelligent participation of citizens through information and communication technology. This new form of governance makes citizens from passive consumers of urban services to active actors who can comment on the kind of service they need. The purpose of this research is to provide macro and generalizable strategies for smart governance in Iranian cities.

    Materials and Methods

    The present research is descriptive-analytical and survey research. Also, in terms of purpose, it is fundamental. According to the nature of the subject and the investigated indicators, documentary research methods and field studies (questionnaires, interviews) have been used to collect information. The questions were collected based on the variables determined by a Likert scale with five options (completely disagree, disagree, have no opinion, agree, completely agree). The validity of the questionnaire was confirmed by experts related to the research and its reliability was confirmed using Cronbach's alpha test. The statistical population of this research includes 170 city managers and university experts in the field of urban planning, which was selected using the purposeful sampling method (170 people). The necessary information was collected through a questionnaire and the output was modeled using the statistical model of Minitab software and structural equations (EQS). Finally, the proposed strategies were extracted in the form of the SOAR strategic model.
     

    Findings

    The results obtained from the analysis of information show that the highest realizability is in the case of indicators of human-social factors, decision-making and intelligent decision-making factors, and infrastructural management factors. In these indicators, the variables of citizens' knowledge and awareness, facilitation of citizens' intervention in the process of local development, and the foresight of urban projects with a specific strategic vision, all have the highest realizability with a statistical average of 1.3 and Friedman's ranking average of 24 and 18. Also, the lowest degree of realizability is related to the variables of project efficiency and effectiveness and citizen survey system and collective and working group belief, whose statistical average is 2.7 and 2.8, respectively, and their Friedman ranking average is 3. Also, the results of the t-test show that out of 24 variables, 10 variables have a critical situation and lack proper realization, and their t-test value is lower than the value of the test (i.e. 3). Moreover, the findings of the research show that the influence of independent variables on the dependent variable can be predicted up to 51% level and the significance between independent and dependent variables is up to 95% level and among the components related to smart urban governance, the components Organizational management with a beta coefficient of 363% and technological factors with a beta coefficient of 206% have the greatest influence on smart governance in Iranian cities. The results of this research show that the most critical executive strategy from the point of view of the stakeholders is the readiness of citizens to participate in planning, the support of citizens and managers for governance, adherence to laws in economic and commercial activities of the municipality, Citizens' commitment and passion for progress and urban development are their place of residence.

    Conclusion

    According to the analysis and investigations carried out about the feasibility and realization of smart urban governance in Iranian cities and based on the opinion of the elite, it is concluded that Iranian cities have strengths and opportunities in the field of smart governance. However, to reach the model of the management-participatory system based on governance with an emphasis on the smartness of the city, in this regard, using the opinions of the elites and the participation of all relevant officials and stakeholders is considered an unavoidable necessity. In this regard, factors such as Citizens' preparedness to participate in planning, support of citizens and managers for governance, commitment to rules in economic and commercial activities of the municipality, community-based management and decentralization of power institutions, and reducing the tenure of government institutions, commitment and citizens' enthusiasm for progress and urban development of their lives can be regarded.

    Introduction

    Today, the concept of cities cannot be assessed without effective green space in its various forms. As centers of human activity and life, cities have no choice but to accept the structure and function affected by natural systems to regulate their sustainability. In the meantime, urban green spaces as a necessary and integral part of the single body of cities have a fundamental role in their metabolism, and their lack can cause serious disturbances in the life of cities. Isfahan city is one of the most important cities in tourism in the country and has been known as the city garden for a long time and is one of the most prominent and beautiful cities in Iran. On the other hand, due to the existence of Zayandehroud (flowing from west to east of Isfahan) and its branches, the spatial distribution of urban parks and green spaces in different regions seems to differ significantly. Therefore, in the current research, we try to analyze the key factors and the main driving forces affecting the distribution of urban green spaces in Isfahan. Then its main elements and factors are presented by designing possible scenarios in the future, the path to achieving environmental justice with a future research approach.  Therefore, the main question of the research is: What are the key drivers affecting the distribution of urban green spaces in Isfahan based on the approach to environmental justice in the future (Horizon 1410)?

    Materials and Methods

    In this study, the research method is applied in terms of the goal and in terms of the way of doing the research. It is a mixture of descriptive-analytical and the explanation of the structure. This is applied as a future research approach and, based on this, we have investigated the most important factors affecting the distribution of urban green spaces with the approach to environmental justice in the city of Isfahan. Information was collected by document method (library resources, scientific journals) and field method (using a questionnaire tool). In this research, the statistical population consists of 28 experts comprising of city managers (mayors, deputy mayors, heads of organizations, and managers of urban areas), members of the city's Islamic Council, experts in the field of civil engineering in the governorate and city affairs office and governorate councils of Isfahan, professors of Isfahan universities, Isfahan Industrial and Isfahan Arts and other universities of this city along with the professors of Shahid Beheshti University and specialists of the urban area. In this research, structured interviews with a number of experts in the fields of planning and urban environment were carried out using the Delphi method to identify the key factors, and then by combining the factors obtained from the interviews and the studied documents in the background of the validity and reliability research of the variables by experts. It was confirmed and finally; the factors were evaluated in the form of a prospective research questionnaire.

    Findings

    Using field and library studies, the most important influencing factors on the distribution of urban green spaces were identified with an emphasis on environmental justice in Isfahan city, and further, using the quantitative method of future research and the use of Micmac software, the degree of influence or effectiveness of the identified factors was determined. Therefore, the research findings show that among the 20 key factors affecting the distribution of urban green spaces with an emphasis on environmental justice, after examining the indicators and extracting the key influencing factors (direct and indirect), 6 key drivers are "the use of emerging and environmentally compatible technologies". "Emphasis on the use of clean fuels in urban areas", "Attention to the economic status of the strata living in cities", "Using regulations and policies in environmental planning by NGOs in Isfahan city", "Investment in environmental infrastructure areas in cities" and "access to suitable fuel energies in cities" that have had the greatest effect on the distribution of urban green spaces with an emphasis on environmental justice in Isfahan city.

    Conclusion

    In a summary of the results of the research, it can be mentioned that attention to the use of emerging technologies in the field of environment and investment in this field can have significant effects on the distribution of urban green spaces and proper access to them by citizens based on the approach of environmental justice in the short term planning horizon of ten years. Moreover, paying attention to the economic structure of the citizens and their financial resources can provide a suitable platform for the distribution of urban green spaces in Isfahan. Currently, the neighborhoods, districts, and urban areas in Isfahan have a better situation in terms of access to urban green spaces and are benefited. On the other hand, less benefited areas are facing deprivation in social and economic fields. In addition, they are facing deprivation of access to urban green spaces. In addition, paying attention to the rules and regulations for the location of urban green spaces, relying on the approach of environmental justice, and involving more non-governmental organizations in the field of provision and optimal access of citizens to green space, is necessary. In the end, the opinion of elite urban experts in the planning horizon of the next ten years in the field of main and key drivers affecting the distribution of urban green spaces can provide a suitable guide map for managers and urban decision-makers in Isfahan.

    The difference in the role and level of actors' intervention in shaping the place, caused by different urban development policies, leads to different results in the place making.The aim of this research is understanding this difference and its impact on the final product (shaping a place and through it the residents’ place attachment). Based on this, the place attachment has been evaluated in the neighborhoods of Eslamshahr with different origins and roles of the actors.For this purpose, the quantitative approach was used to find a significant relationship between the place attachment and the level of intervention of actors. The method of data collection in assessing place attachment was survey by using a questionnaire. In order to evaluate the role of actors, document review and in-depth interview with informants are done. The studied neighborhoods categorized in three types based on based on actors with different roles: "actors with unofficial origins (people)", "actors with official origins (government)" and "actors with a combination of official and unofficial origins (people and government)". The results show in the neighborhoods have formed under the influence of a combination of different actors, place attachment is higher than the neighborhoods have formed only under the influence of official (government) or unofficial (local community) actors. In other words, it can be concluded that the interaction between the actors and supplying the interests of all the involved groups can lead to the transformation of the space into a place for the residents, and thereby improving their place attachment.

    Introduction

    In recent years, the concerns about the fiscal stability of the Tehran municipality have increased. Construction fees, as the main source of municipalities’ revenue, are volatile and unpredictable. During recession periods, the reduction in construction fees enhances the municipality’s budget deficit, and consequently, the municipality issues debt to cover the deficit. An enhanced budget deficit and an increased debt level lead to unsustainable fiscal conditions. In Tehran, recent housing market recessions and covid pandemic have reduced the municipality’s revenues and forced it to borrow money from the banking system. This paper explores the status of the fiscal stability of Tehran municipality in the period 1400-1405.

    Materials and methods:

    In this paper, we use two different approaches, debt to GDP and debt to asset ratios, to forecast the level of municipal debt and investigate the status of the fiscal stability of Tehran municipality. The balance sheet of Tehran municipality (available until 1397) is used to compute the debt-to-asset ratio. We also used the reported debt and GDP level of the municipality of Tehran to calculate the debt-to-GDP ratio of the year 1399 in our analysis. In the next step, we employed fiscal programming and policies framework (FPP) to forecast the revenue and expenses of Tehran municipality. Consequently, the budget deficit of Tehran is forecasted in the period 1400-1405.

    Findings

    According to our findings, Tehran municipality was in an unstable fiscal condition in 1399. The debt to asset ratio was more than 67% in 1397, and the debt to GDP ratio was 16% in 1399. The desired target rate for these two ratios was 50% and 9.9%, respectively. Based on our forecast, the municipality is expected to face a high budget deficit. The municipality will be forced to borrow from the banking system to cover the deficit. Furthermore, It may be unable to settle the previously issued debt. Accordingly, the Tehran municipality debt-to-GDP ratio is expected to reach 25% by the end of 1405.

    Conclusion

    In this paper, we aimed to assess the fiscal stability of the Tehran municipality and suggest a series of reforms to enable the municipality to achieve fiscal stability. The debt to GDP ratio of 16% and the debt to asset ratio of 67% in 1399 demonstrates that the municipality is fiscally unstable. Although the target rate of the debt to GDP ratio is 9.9% in 1405, our forecast shows that the ratio will approach 25 percent by then. Accordingly, the fiscal status of the Tehran municipality will remain significantly unstable in 1405.The required reforms to achieve fiscal stability should be implemented in two dimensions. First, policy reforms are needed to reduce expenses and increase revenues. To prevent the financial crisis, in the medium term, the GDP of Tehran should experience an average increase of 1.54% each year. Second, Institutional reforms are necessary to increase the transparency of budget spending and enhance the efficiency of the reporting process. In this regard, implementing budget classification and coding reforms and fully applying accrual accounting are among the necessary reforms.

    Introduction

    Gravity models are models that investigate the catchment areas of commercial activities and other activities at an urban and regional level. The Huff model is one of the prominent models in this field, which calculates the probability of customer attraction for existing commercial locations and the catchment areas of commercial locations. In Huff's original model to calculate the catchment area of cities’ commercial places, two factors of distance and size of the commercial place are used as influencing factors. The travel time index or the distance between business locations and customers was used for the distance factor, and the size of the business location, the area index was used. During the different years, this model was used in studies modified and adjusted by different researchers. Using network distance instead of Euclidean distance and calculating the attraction power of commercial places or other studied places are among these modifications. In all the research conducted in this field, despite the modifications made in Huff's model, no evaluation was done on the output and results of this model. In this research, the main goal is to provide a method to evaluate the results and outputs of the modified Huff model. The secondary goal of this research is to investigate the spatial distribution of stores and their catchment areas from the point of view of urban planning and to identify the strengths and weaknesses of the existing pattern.

    Materials and Methods

    The methods used in this research are theoretical and subjective. In the theoretical method, after studying the sources (related books and articles), the theoretical foundations and structure of this model were built. In the next step, a map of chain store catchment areas in Buein Zahra city was determined based on Huff's theoretical model and using spatial analysis and network analysis tools in Arc GIS software. The indicators used to measure the attractiveness of the stores (shopping center size) include the size of the store, the number of employees, the variety of products, and the presence of marginal parking around the store. In the next stage, using the questionnaires completed by the residents of the city, their priority of visiting chain stores in the city was questioned. In this stage, the sample was determined using the Morgan method and random spatial sampling, and about 430 residential units were selected as samples. After determining the priority of residents to visit chain stores, the actual catchment area of these stores draws on the map of Buein Zahra city. Finally, two methods were used for evaluation. In the first method, overlaying theoretical and actual map layers, then average, maximum, and minimum indices are extracted based on the theatrical catchment area pixel values in order to determine the degree of correspondence between the actual and theoretical store catchment areas. In the second method, the evaluation was done using the Kappa agreement index.

    Findings

    In Buein Zahra city, nine chain stores exist that are not uniformly distributed and most of them are concentrated in the central area of the city (Imam, Taleghani, and Valiasr streets). In the first stage, using the modified model of Huff, the chain store catchment area was determined. Generated maps show the probability of residents visiting chain stores. These probabilities varied based on the distance between the store and the attractiveness index. To create a final map of the theoretical catchment area based on the highest probability of residents visiting the stores, the probability maps produced for the stores overlaying and draw break lines. With this method, a map of the areas with the highest probability of visiting each store create. Some spaces of the city are placed in the catchment area of two or more stores according to their location about the stores, according to the equal probability of visiting the stores. In the second stage, the actual catchment area of chain stores was produced based on the questionnaires completed by 430 sample households. Findings of this stage show the city area divided into areas where in each area the majority of households have chosen a store as their priority. Based on the findings of this stage, nine catchment areas were identified for chain stores. To evaluate the modified Huff model used in this research, two methods were used: in the first method, the layers of the actual and the theoretical chain store catchment areas overlaid in the ArcGIS software, and using spatial analysis functions, the average, and minimum and maximum values of the pixels were extracted separately. Based on the findings obtained from this stage, the actual and theoretical chain store catchment areas in Buein Zahra city are compatible, although the degree of compatibility is higher for some stores and less for some of them. The highest degree of compatibility and coordination is dedicated to store number 8 (Korush, branch 1). The second method to evaluate the results is to calculate Cohen's kappa coefficient. To calculate this coefficient, the map of the sample points that used to calculate the actual catchment area (the location of 430 sample households) and the final map of the theoretical absorption area overlaid in ArcGIS software and then calculate Cohen's kappa coefficient. Examining the level of agreement using the calculated Cohen's kappa coefficient shows that the accuracy level in the absorption areas of all stores is above 90%, and this indicates the excellent accuracy of the Huff model in determining the catchment area and its proper matching with the actual catchment area.

    Conclusion

    In this research, the main goal is to evaluate the effectiveness of the modified Huff model for identifying the chain store catchment areas in small cities. The results of this research are expressed in two parts: the first part, which is based on the main objective of the article, i.e. the evaluation of the modified Huff model, shows that this model is superior in identifying the locations of chain stores in small cities. Results from methods for evaluating the modified huff model (statistical indicators, as well as Cohen's Kappa coefficient); show that the model outputs are close to the pattern of residents' visits to stores in the city. The second part of the results presented is in line with the secondary goal of the research, which is to investigate the distribution of stores and the formation of their catchment areas in the city of Buein Zahra. The research findings indicate the formation of asymmetric catchment areas with different areas in parts of the city. In the central part of the city, the catchment area is smaller, and with the distance from the city center, the catchment area becomes larger.

    Carrying out large construction projects will undoubtedly be fraught with many risks. In these projects, risks are often ignored or assigned to departments that do not have sufficient knowledge, resources and capacity to manage them effectively, which reduces the quality of the project and in some cases it causes delays in achieving project goals. Therefore, identifying risks, ranking the factors affecting them and also examining the severity of risks are the necessities of implementing any construction project. To achieve this goal, the present study has examined the construction project of Shohada Square in Mashhad. The present study is of descriptive-analytical type. A questionnaire method was used to collect data. The sample population was 51 experts based on Morgan table. The results of the Chi-square test show that the probability of market, financial and managerial risks in the project environment, the risk of multidisciplinary nature among the risks of the inter-organizational environment, as well as political, social and Economics in the external environment of Mashhad Shohada Square are high. On the other hand, the impact on the objectives of financial risks in the project environment, the multidisciplinary nature in the inter-organizational environment, and the occurrence of inflation in the external environment of Mashhad Shohada Square project were ranked higher than other items. Also, the highest level of risk was identified in the project environment, inaccurate estimation of costs, in the inter-organizational environment, delays in granting facilities, and in the external environment, inflation was identified.
