基于 SBM 模型的我国省际能源环境效率研究
Energy Environmental Efficiency Analysis on Chinese Provincial Regional Based on SBM Model
摘要
Abstract
This article combined SBM model and the four-stage DEA method,and evaluated provincial total factor energy environmental efficiency of 30 provinces and cities between 2004 ~ 2012 in China.Based on the non-angle and non-radial ap-proach,the study Shows that:①Environmental constraints impose significant impact on energy environmental efficiency,so ac-curate evaluation of energy environmental efficiency must take environmental pollution comstraints into account.②Over time, energy environmental efficiency diplays kind of tide that"the higher score region getting higher,and lower score getting lower".③The amount of slack in the Tobit regression results show that GDP is a favorable factor for improving the energy environment efficiency,whill Foreign direct investment,industrial structure and energy consumption is unfavorable factors,and technological improvements and environmental management have no significant effect on efficiency.④ Four-stage DEA results indicate that external factors have a significant impact on the energy environmental efficiency,and efficiency can be effectively improved if we can eliminate the impact of external factor to create a relatively fair environment.关键词
