我国危险废物产生量与经济发展的关系及政策启示——基于面板EKC模型的估计

基于面板EKC(Environmental Kuznets Curve)模型实证分析了我国及其东中西部地区1996—2013年危险废物产生量与经济发展的关系,并研究了我国资源化利用水平和无害化处理水平对危险废物产生量与经济发展的关系的影响。结果表明:我国危险废物产生量与经济发展呈现"倒N型",东西部地区呈"N型",中部地区呈"倒N型",总体上我国危险废物产生量随着经济的增长呈现先下降后增长再下降的趋势,但也存在区域差异性,我国东西部地区呈现增长的趋势;我国危险废物综合利用水平对危险废物的减量化具有较大的影响,危险废物资源化利用水平呈现东中西部地区依次递减,而危险废物处置水平对危险废物减量化影响较小。基于上述结论,提出我国危险废物减量化、资源化、无害化的政策与建议。

Panel EKC Estimation of the Relationship between Hazardous Waste GenerationandEconomicDevelopmentinChinaandPolicyImplications

This paper proposes a panel Environmental Kuznets Curve (EKC)estimation of the relationship between hazardous waste (HW)generation and economic development in China in 1996-2013.Meanwhile, the paper explores the impact of the HW utilization and harmless disposal level on the relationship between HW generation and economic development.The results show that firstly,the HW generation nationwide first decreases and then increases,and decreases again with the economic development.However,there is regional difference.The EKC of the Central China presents “inverted-N”type,while that of the Eastern and Western China presents “N”type with increasing tendency.Secondly,the HW comprehensive utiliza-tion has great influence on hazardous waste reduction in China,but the disposal level does not.The HW u-tilization level is decreasing from the east to the west of China.The paper comes up with suggestions on HW reduction,recycling and harmless disposal policy for China’s HW management.
