摘　　要：运用完全分解的因素分解模型探讨了北京市电耗强度变化的原因。研究表明,1998—2007年,电能利用效率的提高推动了电耗强度的下降,产业结构变化对能源强度影响不大,且第二产业及第三产业电能利用水平是导致电耗强度波动的主要原因,因此,提高电能在第二产业的能源消费比重以及提升第三产业电能利用效率水平,是降低电耗强度、提高电能利用效率的有效途径。This paper discusses the reasons for changes of electric energy intensity in Beijing by using the complete factor decomposition model. Researches show that the increase of electric energy efficiency promotes the decrease of electric energy intensity in Beijing during 1998—2007. Structure change has less effect on electric energy intensity. But the low utility level of electric energy in secondary industry and tertiary industry are the main reasons for changes of electric energy intensity in Beijing. Therefore, increasing the proportion of electric energy consumption in secondary industry and improving the electric energy efficiency of tertiary industry are effective ways to decrease electric energy intensity and advance electric energy utility efficiency in Beijing.
