我国城市生活垃圾污染治理效率研究

Research on the Municipal Solid Waste Pollution Governance Efficiency in China

基于DEA模型,选取2017年我国30个省市的截面数据,测算各地区的城市生活垃圾污染治理效率,并用灰色关联度分析模型,探寻影响垃圾污染治理效率的关键因素.结果表明,我国城市生活垃圾污染治理效率偏低,全国仅有北京等9个省市达到DEA有效;治理效率的区域异质性较为明显,表现为东部地区最优,西部地区次之,中部地区最差;要达到高效提高治理效率的目的,关键在于管控好无害化处理能力、无害化处理量和基础设施投资额这三个关键指标.

Based on the DEA model,the cross-section data of 30 provinces and cities in 2017 were collected to measure the regional municipal solid waste pollution governance efficiency in China. The grey correlation analysis model was employed to explore the key factors affecting the governance efficiency of garbage pollution. The results show that the municipal solid waste pollution governance efficiency was low in China,and only nine provinces and cities including Beijing had achieved effective DEA. It was found that the governance efficiency had obvious regional differences,showing that it was the highest in the eastern region,followed by the western region,and the central region was the lowest. To improve the governance efficiency in a more effective way,it is vital to control the three key indicators:harmless treatment capacity,harmless treatment volume and infrastructure investment.
