China's economy in the past 10 years has developed rapidly and achieved great success, but at the same time, environmental problems have been deteriorating, seriously hindering the country's regional sustainable development. This paper proposes a common-weights DEA model based on "the priority of choosing common weights" to assess the environmental performance of 30 provinces from 2006 to 2015 and analyzes regional development in combination with China's economic division. This paper also introduces the biennial Malmquist Productivity Index (BMPI) to study environmental productivity levels during the 11th and 12th Five Year Plans (FYP) from a time series perspective. The results present a large gap in regional environmental efficiency, mainly manifested by the fact that the eastern and northeastern regions' environmental condition is obviously better than that of the central and western regions. BMPI analysis indicates that the overall environmental performances during the 11th and 12th FYPs did not improve significantly, with a clear imbalance in the western region, implying that its development potential is huge. On this basis, we offer some suggestions for improving the environmental performance of different regions.
中国过去 10 年经济快速发展，取得了巨大成就，但与此同时，环境问题也在恶化，严重阻碍了国家的区域可持续发展。本文提出了一种基于“共同权重选择优先”的共同权重 DEA 模型，以评估 2006 年至 2015 年 30 个省份的环境绩效，并结合中国经济分区分析区域发展。本文还引入了双年度 Malmquist 生产力指数（BMPI），从时间序列角度研究了“十一五”和“十二五”期间的环境生产力水平。结果表明，区域环境效率存在较大差距，主要表现为东部和东北地区的环境状况明显好于中部和西部地区。BMPI 分析表明，“十一五”和“十二五”期间的整体环境绩效没有显著改善，西部地区的不平衡明显，表明其发展潜力巨大。在此基础上，我们为不同地区提高环境绩效提出了一些建议。
