本文基于DEA-SBM模型测算了1999 - 2010年我国30个省、市、区和四个区域的全要素能源效率，并利用变异系数和K-Means聚类分析考察了各区域全要素能源效率的差异，最后对各省区的节能减排潜力进行了测度分析。不考虑碳排放约束的省份全要素能源效率被高估，绿色能源效率呈现U型趋势;绿色能源效率按照区域格局由东向西递减。通过聚类分析结果表明，高效率地区的省份是东部沿海省份;中等效率的省份多为中部省市和东北地区，而西部大部分省份效率较低;西部地区节能减排潜力最大，中部和东北部次之，东部最小。
This paper measured total factor energy efficiency of 30 province,city,district and four regional from 1999 to 2010 in China based on DEA-SBM model,and using the coefficient of variation and K-Means cluster analysis examined the regional total factor energy efficiency differences,at the end of each provinces and regions of the energy saving and emission reduction potential of the measure analysis.Research results show that:without considering the carbon emission constraints in the provinces of total factor energy efficiency is overestimated,green energy efficiency presents U trend;Green energy efficiency according to the regional pattern of decrease from east to west.The four major regions of the coefficient of variation is difference, showed convergence trend;By the clustering analysis results in the high efficiency area of the province is the eastern coastal province;The Medium efficiency of the province are mostly central provinces and cities in the northeast,while most of province in western is low efficiency; The potential of energy-saving and emission-abating in western is highest,followed by central and northeastern,eastern is minimum.
