ABSTRACT:one of the indicators that is currently considered in determining the level of development of a country is the amount of electricity consumption and its applications.Providing the needs of the industrial sector for energy,especially electricity, is undeniable and very important and is very effective in the process of growth, development and economic stability.In this study,using time series data and aggregate techniques in econometrics, especially dynamic auto regressive distributed lag models (ARDL) and error correction mechanism (ECM), long-term and short-term relationships of electricity demand model of the industrial sector are estimated. Based on the obtained results,The price elasticity of demand in the industrial sector is equal to 0.453 and it indicates that with a one percent increase in the price of electricity,the amount of demand decreases by 0.453 percent.Therefore, electricity is a low-elastic commodity, This means that the industrial sector is dependent on electricity and other energies cannot be a suitable alternative to it.The results show that all coefficients are significant at the levels of 5 and 10 percent. Also, the results show that the demand for electricity has an important role in the production of the industrial sector and ultimately the country's GDP, so that an increase of 1 unit (ten thousand kilowatt hours) in electricity consumption in the industrial sector can increase GDP by about 23,660 dollars.Keywords: Electricity Demand of Industrial Sector, Price of Energy Carriers, ARDL.

International sanctions against Iran have been lead to an increase in demand of foreign exchange and ultimately cause an increase in exchange rate. In this study, we aim to investigate and forecast the consequences of exchange rate increase on economic growth of major economic sectors of Iran during 1976-2014. For this purpose, we used a short scale macro-econometric model which has been estimated by the new co-integration approach. The results show that an increase in exchange rate will reduce the production of all economic sectors. Also, the growth rate of all economic sectors will be reduced to its minimum and then will increase. Also, we have come to the conclusion that the production of oil & gas sector will be reduced more than the other sectors.
