摘　　要：考察长江流域四川、重庆、湖南、湖北、江西、安徽、浙江、江苏、上海七省二市能源利用效率，比较分析其差异以及原因，寻求提高能源利用效率的途径。首先定义能源利用效率为能源通过要素优化配置产生的技术效率，然后利用数据包络DEA和全要素效率SFA方法进行测度，最后通过比较拉氏指数与迪氏指数的优劣，采用迪氏指数法对能源利用效率影响因素进行分解。计算出七省二市及六部门1997～2006年GDP能耗、能源技术效率和能源利用效率，并分析了结构调整、技术进步和制度进化对能源效率的影响程度。研究表明：（1）结构调整是提高能源利用效率的有力措施；（2）技术进步和制度进化是提高能源利用效率的关键；（3）能源利用效率研究方法应尽量统一并不断改进。The aim of present article is to analyze comparatively the differences and causes of energy use efficiency of seven provinces and two cities（Sichuan Province,Chongqing City, Hunan Province, Hubei Province,Jiangxi Province, Anhui Province,Zhejiang Province,Jiangsu Province and Shanghai City） in the Yangtze River valley and find the way to improve energy use efficiency. First,the article defines the energy use efficiency as technical efficiency realized by elements optimization configuration;then, data envelopment a- nalysis（DEA） and stochastic frontier approach （SFA） will be used as measurement methods; last, after comparing the advantages and limits of Laspeyres index with Divisia index, the latter method will be used to decompose the affecting factors of energy use efficiency. The GDP energy consumption, energy technical efficiency and energy use efficiency of the above mentioned seven provinces and two cities and six branches from 1997 to 2006 were calculated,and the influencing degree that structure adjustment,technological progress and system evolution impose on energy efficiency were analyzed. （1） Structure adjustment is the forceful measure to improve energy use efficiency; （2） Technological progress and system evolution are the key to improve energy use efficiency; （3） Research method about energy use efficiency should be unified as possible as we can and continuously improved.
