基于DEA方法的我国大气污染治理效率评价

选取废气治理设施数、废气处理运行费用和工业二氧化硫、工业烟尘、工业粉尘去除量作为大气污染治理的投入与产出变量,运用超效率DEA模型,对我国各省份2004~2009年大气污染治理效率进行研究.结果表明,研究期内我国大气污染治理效率的省际格局基本不变,中部地区大气污染治理效率高于东部和西部地区;江西、内蒙古等省份大气污染治理效率相对较高,而北京、天津、四川、新疆等省份则相对较低;并据此提出了相应的大气污染治理投入的对策建议.

Study on air pollution abatement efficiency of China by using DEA

Taking the number of waste gas treatment facilities and its operation cost as the inputs,with the outputs of the abatement amount of industrial sulfur dioxide、industrial smoke and industrial dust,super-efficiency DEA model was applied to study the efficiency of air pollution abatement in China’s 29 provinces from 2004 to 2009.The results show that there was no significant change in the pattern of the abatement efficiency among the provinces during our studied period.The provinces in the central region,such as Jiangxi and Inner Mongolia,had relatively high air pollution control efficiency.The provinces in the eastern region,such as Beijing and Tianjin,and in the western region,like Sichuan and Xinjiang,had relatively low efficiency.China should increase air pollution control investment in the central and western regions in order to improve air pollution control efficiency.
