【摘要】 本文使用DEA方法测度了2005-2007年我国各省能源效率。通过在CRS模型中限定资本和劳动力为非意愿变量,发现效率提高的3年间能源技术效率平均提高4.32%,但各省之间的差异没有明显缩小迹象。比较全要素技术效率与能源技术效率得分还可以发现,能源效率低于劳动力和资本效率。进一步利用Malmquist生产指数的测算结果表明,技术进步是目前生产效率提高的主要因素,而且多数省份的技术进步还是倾向于劳动力和资本。更多还原

【Abstract】 This paper measures China’s energy efficiency from 2005 to 2007 under DEA method. After setting capital and labor as nondiscretionary variables,we find that during this period energy technical efficiency (TE) has increased 4.32 percent by average but the differences between provinces hasn’t been significantly narrowed. Compared with TFP TE,energy TE is lower than labor and capital. Furthermore,Malmquist Index results reveal that technological advances is the major power promoting production efficiency and technological advances of most provinces are still inclined to labor and capital.更多还原
