Abstract
We analyze the mechanism for industrial co-agglomeration in Chinese 283 cities to affect haze pollution from 2003 to 2016 and examine the possible mediating effects of urbanization and energy structure between haze pollution and industrial co-agglomeration, finally obtaining the following results. First, industrial co-agglomeration and haze pollution across China, including central and eastern regions keep a typical inverted U-shaped curve relationship. That is, industrial co-agglomeration first promotes haze pollution and then restrains it. However, the impact of industrial co-agglomeration on haze pollution in western China is still on the left side of the inverted U-shaped curve, reflecting a promotion effect. Second, industrial co-agglomeration has a significant spatial spillover effect on haze pollution. Additionally, industrial co-agglomeration can promote haze pollution in local regions but inhibit it in surrounding regions in both the short and long run. In contrast, when the industrial co-agglomeration index exceeds the inflection point (3.6531), it benefits the reduction of haze pollution in local regions, while not being conducive to it in the neighboring regions. Third, industrial co-agglomeration can affect haze pollution through urbanization and energy structure, that is, urbanization and energy structure play an intermediary role between them.
Highlights
Mankind has made great progress in industrialization and urbanization globally, the increasing crisis on resource and environmental has been a matter of concern for the society at large [1]
The “pollution halo” hypothesis holds that foreign direct investments (FDI) can be introduced through green technology to reduce the negative externalities of economic development on environmental pollution [67]
If haze pollution in the region was at a high level in the current period, in the phase it may continue to rise
Summary
Mankind has made great progress in industrialization and urbanization globally, the increasing crisis on resource and environmental has been a matter of concern for the society at large [1]. The answers to these questions can help optimize China’s industrial structure, provide scientific reference for haze pollution governance Based on these factors, this study collects urban panel data in 2003–2016 from 283 Chinese cities to estimate the degree of co-agglomeration of producer services and manufacturing and uses the PM2.5 concentration data monitored by satellites to represent haze pollution. Dynamic spatial panel model and mediating effect model are used to analyze the impact of co-agglomeration of producer services and manufacturing on haze pollution and its possible transmission mechanism. We calculates the industrial co-agglomeration of producer services and manufacturing index of Chinese cities, reveal the relationship in the impact of industrial co-agglomeration on haze pollution and further compare the direct and spillover effects of that in both short and long run. Important, controlling haze pollution contributes to the physical and mental health of public, provides a better living environment for residents, and increases their sense of happiness
