中国省际环境经济效率的测算——基于WTP-DEA模型的实证研究
发布时间：2019-07-04 20:41
【摘要】：本文在分析环境经济系统结构的基础上,引入了碳排放、耕地投入、科教投入等指标,构建了较完善的评价指标体系,进一步采用社会支付意愿(WTP)货币化加权方法来降低投入产出指标的维度,从而建立了环境经济效率测算WTP-DEA模型,并对2005-2014年中国30省份环境经济效率进行了实证研究。研究结论表明:目前我国东部地区环境经济效率高于全国平均水平,中部地区环境经济效率略低于全国水平,西部地区环境经济效率则低于全国水平;提出并验证了以松弛变量与投入原始值的比值为投入低效性度量参数的方法;通过将WTP-DEA模型与未降维的DEA模型对比分析,验证了WTP-DEA模型的计算结果具有更高的可区分度。最后,根据实证结果提出了对策建议。

[Abstract]:Based on the analysis of the structure of environmental and economic system, this paper introduces carbon emission, cultivated land input, science and education input and other indicators, constructs a more perfect evaluation index system, further adopts the (WTP) monetization weighting method of social willingness to pay to reduce the dimension of input-output index, thus establishes the WTP-DEA model for measuring environmental economic efficiency, and makes an empirical study on the environmental economic efficiency of 30 provinces in China from 2005 to 2014. The results show that the environmental economic efficiency in the eastern part of China is higher than the national average level, the environmental economic efficiency in the central region is slightly lower than the national level, and the environmental economic efficiency in the western region is lower than the national level, and the method of taking the ratio of relaxation variable to the original value of input as the measurement parameter of input inefficiency is put forward and verified. By comparing the WTP-DEA model with the unreduced dimension DEA model, it is verified that the calculated results of the WTP-DEA model have higher discriminability. Finally, according to the empirical results, the countermeasures and suggestions are put forward.
