In this study, the static and dynamic spatial Durbin model between industrial structure and haze pollution in Yangtze River Delta is constructed. Later, the spatial spillover effect and time lag effect of haze pollution in Yangtze River Delta are analyzed. The impact of rationalization and upgrading of industrial structure on haze pollution and its spatial spillover effect are discussed. The results show that: (i) PM2.5 has a significant positive spatial spillover effect and time lag effect; (ii) in the short run, the rationalization and upgrading of industrial structure has no inhibitory effect on haze pollution, while the rationalization and upgrading of industrial structure of surrounding cities has an inhibitory effect on local haze pollution; (iii) in the long run, the rationalization and upgrading of industrial structure of surrounding cities have an inhibitory effect on local haze pollution; (iv) economic growth, FDI, the number of Industrial Enterprises above Designated Size, and population density also have spatial spillover effects on haze pollution. Therefore, considering the spatial spillover effect of haze pollution from the perspective of urban agglomeration and long-term, strengthening the joint prevention and control and comprehensive treatment among cities, further promoting the rationalization and upgrading of industrial structure is conducive to reducing haze pollution.

重新审视长江三角洲地区产业结构对烟霾污染的影响

本研究建立了长江三角洲产业结构与霾污染之间的静态和动态空间杜宾模型。然后，分析了长江三角洲霾污染的空间溢出效应和时滞效应。讨论了产业结构合理化和升级对雾霾污染的影响及其空间溢出效应。结果表明：（i）PM2.5具有显着的正空间溢出效应和时滞效应；（二）从短期看，产业结构的合理化和升级对雾霾污染没有抑制作用，而周边城市产业结构的合理化和升级对局部雾霾污染没有抑制作用；（iii）从长远来看，周边城市产业结构合理化和升级对当地烟霾污染具有抑制作用。（iv）经济增长，外商直接投资，规模以上工业企业的数量和人口密度也对烟霾污染具有空间溢出效应。因此，从城市群和长远的角度考虑雾霾污染的空间溢出效应，加强城市之间的联合防控和综合治理，进一步促进产业结构合理化和升级，有利于减少雾霾污染。
