摘要
基于2006-2015年六个国控标准的生活垃圾焚烧厂二噁英检测面板数据,运用双重差分(Difference in Difference,DID)分析生活垃圾焚烧产生的二噁英污染对不同地区婴儿死亡率(IMR)的影响。结果发现:不论是Reduce-form方程回归结果还是二阶段回归结果,都证明整个研究期垃圾焚烧并未显著增加IMR值,即二者之间不存在显著性影响。病理学检验和异质性检验结果则表明,源于较为严格的环境污染控制措施和技术,有垃圾焚烧厂的行政区其IMR值与对照区并无显著区别。对于我国日益增长的生活垃圾产生量,若能合理规划好邻避距离,并执行严格的排放标准,垃圾焚烧是解决垃圾围城的较好方法。根本举措仍需加强源头减量和生活垃圾分类,降低垃圾焚烧的二噁英污染。
Based on the penal data of dioxin detection of six state-controlled domestic waste incinerators from 2006 to 2015, the effects of dioxin pollution from MSW incineration on the infant mortality rate （IMR） in different regions are analyzed by using double difference in difference （DID）. Results show that both the regression results on the Reduce-form equation and 2SLS regression results prove that the IMR doesn＇t significantly increase during the entire study period. Furthermore, the results of pathological examination and heterogeneity test indicate that there is no significant difference between the waste incineration plant and the control region due to stricter environmentally controlling measures and technologies. For the increasing production of domestic waste in China, if we can properly plan the distance between our neighbors and enforce strict emission standards, waste incineration is a better way to solve the problem of garbage siege. The fundamental measures are to strengthen source reduction and classification of domestic waste and reduce dioxin pollution from waste incineration.
