摘要: 运用SBM-Tobit两阶段模型,对中国各省市的能源效率进行分析。运用考虑非期望产出的SBM模型对中国各省市1995—2010年的能源效率进行了评价,研究结果表明,上海、广东、海南和青海四省市的能源效率最高,贵州最低。运用面板Tobit模型对影响能源效率的因素进行回归分析的结果表明,优化产业结构、改善能源结构、加强技术引进,以及提高政府影响力都有助于能源效率的改善;而内部技术创新和市场化程度对能源效率的影响还难确定;社会经济发展水平对能源效率的影响正经历一个由负转正的过程。

关键词: 能源结构, 能源效率, SBM模型, Tobit模型

Abstract: With the SBM-Tobit two-stage model, an analysis is given on energy efficiency of different provinces and cities in China. The SBM model considering undesirable outputs is first used to evaluate the energy efficiency of Chinese provinces and cities from 1995 to 2010, whose results show that Shanghai, Guangdong, Hainan and Qinghai have the highest energy efficiency while Guizhou ranks the lowest. The panel Tobit model is then adopted to give a regression analysis, whose results indicate that the factors influencing energy efficiency include optimizing industrial structure, improving energy structure, reinforcing technological introduction and enhancing government influence. It is still difficult to explain the impact of internal technical innovation and market level on energy efficiency, and the effect of social and economic development on energy efficiency is changing from negative to positive.

Key words: energy structure, energy efficiency, SBM model, Tobit model
