摘　　要：运用对数平均迪氏指数法对2000—2008年我国能源强度、电力强度变化的情况及因素进行了分析,结果表明:行业能耗变化对能源强度的变化起主导作用,符合这段时期我国重化工业化的特征;行业电耗变化和结构变化同时引起电力强度的变化,但行业电耗变化起主导作用,这与电能在终端能源消费的比重不断提高密切相关。Using Logarithmic Mean Divisia Index （LMDI）, this paper analyzes the changes and modulating factors of energy intensity and electricity intensity in China from 2000 to 2008. The results indicate that energy consumption changes of sectors plays a leading role in the changes of energy intensity, which coincides with the characteristics of the heavy industrialization in this period. Changes in the sector electricity consumption and the sector structure also lead to changes of electricity intensity, with the sector electricity consumption changes playing the leading role, which is closely related to the ever-increasing percentage of the electricity consumption in the overall end-use energy consumption.
