| Summary: | In this research, By using data envelopment analysis method and output distance functions to decomposes energy productivity change into four components; technical efficiency change, technological change, changes in capital to energy ratio and labor in energy ratio In the industrial sector of the country Iran during the period 2014-2004. To this end, the output-axis data envelope analysis method has been used with the assumption of constant returns to scale. The results show that the effect of changing the ratio of capital to energy is a major factor in reducing the of energy intensity in the industrial sector of the Iran, changes technological progress, changes labor- energy ratio and changes technical efficiency drove up energy intensity in most industries.
