摘　　要：以煤电产业为研究对象,在已有研究的基础上将发电煤炭消耗量作为投入指标、将煤炭发电总量作为产出指标,构建煤电产业生态效率测度模型,并考虑宏观因素在纯技术效率和规模效率两方面对煤电产业生态效率的影响,利用DEA三阶段模型对中国30个省份的区域生态效率进行实证研究。研究发现:①规模以上工业企业R&D经费投入对煤电产业生态效率的影响是负向的,对经济发展的影响是正向的。②第三产业规模虽然促进了经济发展,但是整体来说抑制了煤电产业生态效率的提升。③教育经费的投入对煤电产业生态效率的影响是正向的,对经济发展的影响是负向的。④我国西部地区煤电产业生态效率处于前沿面,从纯技术效率来说,中部地区的生态效率较低;从规模效率来说,西部生态效率优于东部;整体上,东部地区综合生态效率低的原因是由于东部地区的规模效率较低引起的。This paper takes the coal power industry as the research object,takes the coal consumption of power generation as the input index and the total amount of coal power generation as the output index,constructs the measurement index of ecological efficiency of coal power industry,and considers the impact of macro factors on the ecological efficiency of coal power industry from the aspects of pure technical efficiency and scale efficiency,This paper makes an empirical study on regional ecological efficiency of 30 provinces(except Tibet)in China by using DEA three-stage model.The results show that:①The R&D investment of industrial enterprises above designated size has a negative impact on the ecological efficiency of coal power industry and a positive impact on economic development;②The proportion of tertiary industry in the ecological environment of coal power industry is restraining,but it is promoting economic development;③The investment of education funds has a positive impact on the ecological efficiency of coal power industry and a negative impact on economic development;④The ecological efficiency of coal power industry in Western China is at the forefront.From the perspective of pure technical efficiency,the development of ecological efficiency in Central China is slow;In terms of scale efficiency,the development of ecological efficiency in the west is better than that in the East;From the overall analysis,the reason for the low comprehensive ecological efficiency in the eastern region is due to the low scale efficiency in the eastern region.
