Abstract

Based on analysis on dynamic characteristics of energy intensity in three industries of Anhui province from 1995 to 2009, decompositions of energy intensity’s dynamic change was investigated proceed year by year, by the Laspeyres model. The result showed that: the reduction of energy intensity in the past decades was attributed to the improvement of industries’ energy efficiency, especially the improvement of secondary industries’ energy efficiency. At last, theoretical basis was provided for the adjustment of the secondary industries’ energy structure, by contrasting correlation coefficient of energy structure and energy intensity in the secondary industry.
