中国各地区火电行业经营能力与环境能力的评价与比较

本文分别利用结合管理策略的自然可处置和管理可处置径向DEA（data envelopment analysis）方法测度了中国29个省、直辖市和自治区火电行业2001-2011年期间的合成效率和曼奎斯特合成指数。研究结果表明：中国东部地区火电行业的经营能力和环境能力均高于其他两个地区，中部地区经营能力不如西部地区而环境能力强于西部地区；中国各地区火电行业经营能力和环境能力整体处于改进状态；“十一五”期间，东部地区经营能力和环境能力改进情况均好于中部和西部地区，西部地区经营能力提升情况好于中部地区，而在环境能力的提升方面则不如中部地区；“十一五”期间更严格的环境管制规则并没有抑制三个地区火电行业的经营能力和环境能力的改进情况。

Evaluation and Comparison on Operational and Environmental Performance of Chinese Regional Coal-fired Power Industry

This study measures the unified efficiency and Malmquist unified index of coal-fired power industry of 29 administrative regions in China during the period of 2001-2011 used radial DEA methodology under natural disposability and managerial disposability based on corporate strategy. The measurement of the unified efficiency scores under natural and managerial disposability show that both of the operational performance and environmental of coal-fired power industry of the east are better than the other two regions and the central is second in operational performance while it ranks last in environmental performance. The measurement of Malmquist unified indices show that both the improvement of operational performance and environmental performance of coal-fired power industry in the east are better than the other two regions and the west is superior to the central in the operational performance progress while is inferior to the central in the environmental performance improvement during “11th five-year” Plan period. In addition, this study shows that more stringent environment regulation during “11th five-year” Plan period has not suppressed the improvement of operational performance and environment performance.
