长江经济带产业能耗因素分解与效应分析

Analysis of decomposition and effect of energy consumption factors in the Yangtze River Economic Belt Industry

基于2006-2012年数据,利用LMDI模型计算发现,产值效应是长江经济带能耗增加的主要因素,结构效应影响较小,能源强度效应则是能耗降低的关键因素。具体而言,二三产业产值效应是长江经济带能耗增加的主要因素;结构效应对第一产业能耗影响较大,对二三产业能耗影响较小;二三产业能源强度效应是长江经济带能耗下降的关键因素。

Based on the data from 2006 to 2012 and by using LMDI model calculation,we found that the output effect was main factors for energy consumption increase of the Yangtze River economic belt,that the influence of structure effect was small and that energy intensity effect was the key factor to reduce energy consumption. Especially,the second industry and the third industry output effect were main factors for energy consumption increase of the Yangtze River economic belt,the structure effect had great influence on the first industrial energy consumption,less impact on energy consumption of the second industry and the third industry,energy intensity effect of the second industry and the third industry were the key factors to reduce energy consumption.
