Abstract: 

The purpose of this paper is to analyze energy intensity of manufacturing industries in Iran. The analysis uses Laspeyres index and Arithmetic Mean Divisia decomposition techniques and data of Iranian manufacturing industries with more than 10 employees for the period 1374 to 1386 from the Statistical Center of Iran.
The factors considered are changes in production structure (i.e. structural effect) and sectoral energy intensities (i.e. intensity effect). The results show that the changes in sectoral energy intensity play a greater role in the variation in total energy intensity of Iranian manufacturing compared to changes in the production structure of industries. However, in some cases both structural and intensity effects have been at work. In most cases the intensity effect has worked in favor of reducing energy intensity.
