| 摘 要： | 传统的单要素电耗强度指标,不能很好地反映真实的电能效率,因此,采用DEA方法,测算了1998—2007年中国33个工业行业的全要素电力能源利用效率;利用Tobit模型分析了电能利用效率的影响因素。实证结果表明:中国工业行业电能利用效率普遍偏低,在样本期内没有明显地收敛趋势。行业结构、技术进步与电能效率正相关,行业集中度、电力价格与电能效率负相关,产权结构的影响则呈现出波动特征。优化行业结构、推动技术进步、保持行业适度竞争、深化电价改革有助于工业电能效率的提高。

| Abstract: | Traditional single-factor electricity intensity indicator can not reflect the real electricity consumption efficiency accurately.With the help of Data Envelopment Analysis(DEA) approach,the total factor electricity consumption efficiency of China's industry in 33 industrial sectors from 1998 to 2007 is measured,and the influence factors of the efficiency is explored by using Tobit model.The results show that China's industrial electricity efficiency is low in the overall level and does not has significant c... |
