福建省城市全要素能源效率研究——基于双前沿面DEA模型

An Analysis On Urban Total Factor Energy Efficiency In The Fujian Province——Based On Double Frontiers DEA Model

针对传统DEA模型在分析能源效率时存在的问题,引入无效效率前沿(悲观)DEA模型,并综合考虑有效效率前沿(乐观)和无效效率前沿(悲观)两个方面,建立双前沿面DEA模型,综合研究全要素能源效率问题。进一步地,运用双前沿面DEA模型对福建省各地级市的全要素能源效率进行实证研究。实证结果显示:福建省乐观全要素能源效率和综合全要素能源效率存在一定的差异,后者的变化趋势较前者更为明显,表现出明显的收敛性。这在一定程度上说明了运用双前沿面DEA模型研究能源效率的必要性和有效性。

Since there are defects when using the traditional DEA model to analyze energy efficiency, this article will in- troduce the pessimistic DEA model; consider two aspects of optimistic energy efficiency and pessimistic energy efficiency, namely based on the double frontiers DEA model to analyze energy efficiency issue. Further, the article uses the double frontiers DEA model, empirically analyzes the total factor energy efficiencies of nine well-developed cities in Fujian Prov- ince among 2000-2012. The empirical results indicate that, there is a difference between the optimistic total factor energy efficiency and the comprehensive total factor energy efficiency, the variation trend of the latter is more obvious than the for- mer. To a certain extent, this shows that using the double frontiers DEA model to measure energy efficiency issue is neces- sary and efficient.
