如何做好节能减排,提高用能效率进而提升经济增长的质量逐渐成为中国经济发展的重大挑战之一.在经济增长与节能减排双重目标约束下考察中国能源效率现状;同时结合四阶段全局DEA和方向距离函数,从外部运营环境和能源生产/消费行业内部因素两个角度揭示中国全要素能源效率的关键影响因素,进而探讨中国能源效率提升的可行路径.结果表明：外部运营环境中的产业结构、经济开放程度、基础设施以及行业内部的技术、管理、规模水平每提高1个百分点,区域全要素能源效率分别提高-0.0601、0.0179、0.0136、0.4679、0.3972、0。4350个百分点;2003—2010年间,中国区域全要素能源效率从0.8391降至0.8202主要是因为行业内部效率的总体下降,而行业内部效率下降则归咎于行业内部规模效率的逐年降低.因此,合理调整行业规模,提高规模效率是现阶段中国提高区域用能效率亟待解决的重大问题.首次从外部运营环境和行业内部因素两个角度来探讨能源效率问题,有助于厘清各影响因素对能源效率的作用.

英文摘要：

It has been one of the great challenges for economic development of China that how to save energy and reduce pollutant emission,in order to improve economic quality.We would estimate the Chinese energy efficiency with the constraint of economic growth,energy conservation and emission reduction,and reveal the influence factors of Chinese total energy efficiency,in the aspect of external operating environment and industrial internal factors,combing four-stage DEA method and directional distance function.Then the feasible way to improve the energy efficiency of China would be discussed.The empirical results suggested that industrial structure,degree of economic opening,infrastructure,technology,management,scale improve 1%,then the regional total factors energy efficiency would improve —0.060%,0.0179%,0.0136%,0.46795,0.3972%,0.4350%,respectively.During 2003-2010,the regional total factor energy efficiency dropped from 0.8391 to 0.8202 mainly because the industrial internal efficiency decreased.But the decreasing of internal efficiency was due to the reduction of internal scale efficiency.Therefore,adjusting industrial scale and improving scale efficiency were great problems to improve the regional energy efficiency for current China.Studying the energy efficiency in the aspect of external operating environment and internal factors,was helpful for distinguishing influence factors’ effect on energy efficiency.
