The effect of urban regeneration components on the development of urban regeneration model (A case study: worn-out tissues of Tehran)

Reconstruction of worn-out urban structures has always been considered as one of the goals and policies of the government in the country's development programs. Sustainable urban regeneration as a new approach is able to reduce or eliminate many problems and challenges of cities, especially in the field of environment. The aim of this study was to present a new model of sustainable urban regeneration in Tehran.Material and

The present study is descriptive-exploratory. First, the components of sustainable urban regeneration were identified using semi-structured interview tools. The statistical population was experts in the field of urban management - environment and random sampling method. The number of samples was selected using the snowball technique and the principle of theoretical saturation of 22 people. Content analysis method was used to extract the model and finalize it. Pearson correlation coefficient was also used to ensure the relationship between variables.

101 initial codes were extracted from the analysis and analysis of interview data based on the principles of repetition, emphasis and importance. Finally, the concepts of sustainable urban regeneration were classified based on 5 components, 17 categories and 101 behavioral descriptions. Also, based on the results of descriptive statistical test, the mean of the components was above average and all of them had a standard deviation of less than one. According to the degree of correlation coefficient between the variables, the research has a direct and strong relationship.Discussion and

Among the 17 selected categories in the present study, 7 categories (identification and cooperation with involved institutions and trustees, attention to the main needs of communities, empowerment of stakeholders and institutions involved, urban development capacity, status of urban infrastructure, information and interactive infrastructure, Investment infrastructure) are new.
