摘要
传统的能源效率评价模型往往只涉及能源消耗及经济产出两类变量,忽视了能源消耗带来的环境影响及能源与相关要素的替代作用。本文在全要素能源效率的框架下,统筹考虑能源的非期望产出和相关要素,基于超效率DEA方法构建了一种新的能效评价模型。利用1995~2005年我国28个省区面板数据进行的实证研究表明,我国总体能源效率偏低,在维持一定水平后呈现缓慢下降的趋势,区域差异较为显著。
The traditional evaluation models of energy efficiency often only involve energy consumption and economic output, environmental impact of energy and substitution effect between energy and related factors are neglected. Under the frame of total factor energy efficiency, undesirable output and related factors about energy are considered, and then a new evaluation model of energy effioiency is established in this paper based on super DEA method. The empirical research using panel dates during 1995 and 2005 shows that China＇ s overall energy efficiency is low and it has a slow downward trend after maintaining a certain level, regional differences are also significant.
