中文摘要：

利用偏离—份额分析模型对中国1985—2012年间30个省域的能源效率变化分别进行三次产业与不同阶段的分解与比较。研究结果表明,各省域能源效率增长主是由内部增长效应推动的,结构变迁效应对能源效率增长的贡献较小,且普遍存在结构负利现象,但就作用程度大小而言,2002年以后结构负利的作用小于结构红利,中国市场化改革在能源方面的结构效应正随着时间的推移而显现。本文认为,为了有效提高能源效率及其增长率,应当进行适当的能源价格调整,放松对能源价格的管制力度,并加快建立省际间能源自由流动机制的步伐,促进能源在省际间的自由流动。

英文摘要：

With Shift-Share Analysis Model, the paper resolves and analyzes energy efficiency change of China＇s 30 provinces from 1985 to 2012 based on three industries and different stages. The findings are as follows： provincial energy efficiency growth is mostly promoted by within-growth effect; the contribution of structural change effect to energy effi- ciency growth is relatively little and there exists structural burden phenomenon generally; however, the effect of structu- ral burden is lower than that of structural bonus after the year of 2002; and the energy structural effect of China＇s reform of marketization is improving gradually as time goes by. It thinks that it is necessary to adjust energy price moderately, release the regulation of energy price, and accelerate the establishment of free flow mechanism of energy between provinces to promote free flow of energy to effectively improve energy efficiency and its growth rate.
