基于全要素投资效率框架,结合能源效率的内涵与特点,构建了以能源消费总量、从业人员总数和资本存量为投入指标、GDP为产出指标的能源效率评价指标体系;基于超效率DEA方法建立了能源效率评价模型,并对我国2000-2010年29省进行了实证研究.结果显示:东部能源效率最高,中部次之,而西部能源效率最低;中国能源效率变异系数先降后升,省际能源效率差距逐渐拉大.与传统的DEA方法相比,基于超效率DEA的能源效率评价模型更具应用优势.
Based on the framework of total factor investment efficiency and the connotation and characteristics of energy efficiency, an energy efficiency evaluation index system based on total energy consumption, total number of employees and capital stock as input indicators and GDP as output indicators was constructed. Based on the super efficiency DEA method The model of energy efficiency evaluation was established and the empirical study of 29 provinces in China from 2000 to 2010. The results showed that: the eastern part of the highest energy efficiency, followed by the middle, while the western part of the lowest energy efficiency; China’s energy efficiency coefficient of variation decreased first and then increased, the provincial Compared with the traditional DEA method, the energy efficiency evaluation model based on the super-efficiency DEA has more application advantages.
