input-output model

In this research, the effect of changes in energy prices on output of different sectors by using of regional input output of Hormozgan province is investigated. The AFLQ method is used for regionalization of national I_O table. Three scenarios for the increase in energy prices have been considered. The results showed that except of water, electricity and gas/ sector, the output of other sectors has decreased. In the first scenario, the increase in the output of Water, Electricity and Gas/ sector was equal to 38574.52 million Rials whereas the output of transportation sector had the largest decrease in production. Industry and agriculture sectors are the other sectors that have the largest decrease in output after transportation.Total decrease of regional output in first scenario was 1896633.17 million Rials. As a result of the research, 20% increase in the price of energy carriers, about 0.28% of the total production of the province has decreased. In the second and third scenario total decrement of regional output was 512973.80 and 3048927.86 million Rials, respectively. Decrement of agriculture output in these two scenarios was 362099.15 and 512973.80 million Rials. Considering the importance of the agricultural sector in food production, supporting the production of this sector is necessary using appropriate policies such as guaranteed purchase or decrease of tax rate and technology subsidies in different sectors. These policies can provide the necessary incentives to adjust towards more efficient energy technologies, in order to ultimately reduce the negative effects of the increase in the price of energy.

The purpose of this study is to prioritize the economic activities in Yazd Province, Iran, with a sustainable development approach and an emphasis on the importance of water intensity in economic activities. Therefore, multiple criteria were used to prioritize the activities that cover the economic, social and environmental dimensions of sustainable development. In the first stage, the SFLQ method was used to prepare an input-output table for Yazd Province. Then, the economic activities in the province were prioritized in terms of six criteria including the intensity of interdepartmental communication and value-added (economic dimension), job creation (social dimension) as well as energy intensity, water intensity and pollution (environmental dimension). Moreover, a combination of an input-output model and the TOPSIS method was applied. According to the results of this study, among the activities in the province, "transportation" proved to have the highest priority. It was also found that the ignorance of water use as an important criterion can lead to significantly different prioritization results.
