基于数据包络分析的区域全要素能源效率分析

Regional Total Factor Energy Effi ciency Based on the DEA Method

全要素能源效率指标避免了传统衡量能源效率的单要素指标的局限性。文章采用全要素能源效率指数作为能源效率的衡量指标,基于数据包络分析方法,利用重庆市直辖以来的经济产出、劳动力、资本存量和能源消费等数据,测算了1997～2008年间的全要素能源效率。结果表明,重庆市各年的能源效率处于较稳定的位置,期间共有4年处于相对较优状态。根据实证分析结果,提出了改进能源效率的建议。

The index of total factor energy efficiency can overcome the disadvantage of the single factor energy efficiency. This paper we use the total factor energy efficiency as the evaluation indictor of energy efficiency. With the data of GDP output, labor force, capital stock and energy consumption after Chongqing became a municipality, we use DEA method to evaluate the energy efficiency of Chongqing during 1997-2008. The main conclusions are as follows： overall, the energy efficiency of Chongqing is in a stable position, there are four years on the efficiency frontier surface. According to the empirical research, we give some advice to improve the energy efficiency.romoting technology progress.
