基于超效率SBM模型的安徽省大气环境效率分析

Analysis of atmospheric environmental efficiency in Anhui province based on super-efficiency SBM model

基于安徽省2010—2018年各投入产出的面板数据,采用考虑非期望产出的超效率SBM(Slack-Based Measure)模型测算安徽省16市大气环境效率,并利用STATA软件分析改善大气环境的内在要素.实证结果表明:安徽省大气环境效率整体偏低且呈现“皖中>皖南>皖北”的特点;加大工业R&D经费和废气治理设备运用运行费用投入有利于降低大气污染物的产生,且后者效果更为显著,据此给出大气治理投入方面的建议.

The super-efficiency slack-based measure(SBM)model considering the unexpected output was used to calculate the atmospheric environmental efficiency of 16 cities in Anhui province based on the panel datas of input and output of Anhui province from 2010 to 2018.And STATA software was used to analyze the internal elements of improving atmospheric environment.Empirical results show that the atmospheric environmental efficiency of Anhui province is generally low and presents the characteristic of“central Anhui>southern Anhui>northern Anhui”.It is beneficial to reduce the production of air pollutants to increase the investment of industrial R&D and the operation cost of waste gas treatment equipment,and the latter effect is more significant.Based on this,some suggestions on the input of atmospheric governance were given.
