Decomposition of Electricity Consumption Intensity of High Energy-consuming Industries in Shanxi Province Based on LMDI Method

Abstract

In this paper, the electricity consumption intensity of the high energy-consuming industries in Shanxi province from2007 -2012 is decomposed based on LMDI method, in which the affecting factors involve structure effect and intensity effect. The results show that the structure adjustment of Shanxi province is the main driver which declines the electricity consumption intensity for high energy-consuming industries. For most industries, the structure effect declines the intensity with a high contribution proportion. Meanwhile, the contribution proportions of efficiency effect for most industries are less than the corresponding structure effect. The totla effect of each high energy-consuming industry is shown in table 4, in which the totoal effect of Non-ferrous metal smelting and rolling processing industry is relative higher than other industries, and the effect of Black metal smelting and rolling processing industry is just smaller than it.
