  In this study, we investigate the long‐run relationship between demand forimports and the relevant determining factors. We use the method of leastSquares Engel Granger (1987) and Maximum Likelihood Johansen (1988) aswell as Joe Hansen and Joe Sylyvs (1990) to estimate the Long‐Run ImportDemand Function.To have a better assessment of the effectiveness of trade policies; a logicalunderstanding of demand for imports is of particular importance. Our studyshows that the oil revenue, real income, and GDP evaluated at domesticprices, are positively related to demand for imports. On the other hand, therises of price of imported goods relative to the price of domestically producedgoods and currency devaluation have a negative effect on demands forimports of intermediate goods as well as consumption and capital goods.

  The purpose of this article is to evaluate the effect of industrial concentration and import of capital goods on the intensity of energy consumption in Iranian industries. Industrial concentration index has been calculated using Herfindahl-Hirschman method and relative entropy. In this research, the panel data method and the fixed effects model were used to estimate the coefficients of the models. The research findings indicate that between 2002 and 2018,  industrial concentration and import of capital goods have a positive and statistically significant effect on the intensity of energy consumption. So that, one percent increase in the share of the industry in the market, increases the intensity of energy consumption between 0,089 to 0.203 percent. Also, the price of energy carriers has a negative effect on the intensity of energy consumption. Considering the inverse relationship between the price of energy carriers and energy intensity and the low elasticity of the price, it is  necessary that incrementally raise the energy prices for industries logically causing environmental pollution to decrease their energy intensity. It is suggested that capital goods enter industries that have low energy consumption. Manuscript profile
