摘要
本文尝试以西部地区为研究对象,利用改进的DEA模型,对西部地区2000—2010年的生态效率进行测度,并在此基础上,进一步利用Malmquist指数做动态分析。结果表明,自西部大开发以来,整个西部地区生态效率的均值小于1,未达到最有效的生产前沿,但跨期呈波动上升趋势;省际在效率水平和冗余率两方面存在明显差异;能源的消耗和工业"三废"等污染物的排放是影响非生产前沿面地区生态效率的主要因素;西部地区生态效率提升主要得益于技术进步的贡献,而纯技术效率的贡献不显著,规模效率的贡献为负。
This paper evaluated the eco-efficiency based on DEA model and Malmquist productivity in- dex based on the data of western China＇s provinces from 2000 to 2010. The results showed as follows, the average value of eco-efficiency was less than 1 since the west development, which did not reach the most effective production frontier, but the whole eco-efficiency increased with fluctuations cross periods~ there were the striking differences among provinces from two respects of efficiency and redundancy rate~ such pollutants as waste gas, industrial waste water and solid wastes and such natural resources as energy were major factors influencing the eco-efficiency~ the promotion of western eco-efficiency was mainly due to the contribution of technological advance, however, the contribution of technical efficiency was insignificant and the contribution of scale efficiency was negative. Finally, this paper pointed out the policy implications on the basis of the empirical conclusions.
