摘　　要：通过分析DEA—Malmquist指数能合理地测度省域节能减排效率。将中国各省份作为开展节能减排效率评价的基本单位,搜集各省份相关指标数据组成面板数据,运用DEA—Malmquist指数模型对各省的节能减排效率进行测度,并分解成技术进步与技术效率,再从全国、区域、省域层面进行实证研究。结果表明:中国的节能减排效率正在提升,得益于技术进步;东中西区域节能减排效率存在差异,东部的效率要高于中西部的水平;绝大多数省份节能减排效率在进步,同时省际节能减排效率存在收敛现象。最后根据实证研究的结果,提出相应的政策建议。The paper conculudes that the DEA-Malmquist productivity index is the right method for measuring the efficiency of energy conservation and emission reduction in the provinces, and applies DEA-Malmquist productivity index to measure the efficiency of 30 provinces in China, based on panel data. The results of our study show that the efficiency of energy conservation and emission reduction is going up in China as the result of technical growth; the efficiency of energy conservation and emission is different among Easten area, Mid area and Western erea; the energy conservation and emission reduction in most of provinces are improved, while interprovincial efficiency exists remarkable convergency tendency. Accordingly, the relevant policy proposals are given at last.
