Can Industrial Collaborative Agglomeration Reduce Haze Pollution? City-Level Empirical Evidence from China

Area of Science:

• Environmental Science
• Urban Economics
• Regional Studies

Background:

• Industrial co-agglomeration is a key factor in economic development.
• Haze pollution poses significant environmental and health challenges in China.
• Understanding the interplay between industrial location and pollution is crucial for sustainable development.

Purpose of the Study:

• To analyze the impact of industrial co-agglomeration on haze pollution in Chinese cities.
• To investigate the mediating roles of urbanization and energy structure.
• To examine spatial spillover effects of industrial co-agglomeration on haze.

Main Methods:

• Analysis of data from 283 Chinese cities (2003-2016).
• Econometric modeling to assess the relationship between industrial co-agglomeration and haze pollution.
• Examination of mediating effects and spatial spillover effects.

Main Results:

• A non-linear inverted U-shaped relationship between industrial co-agglomeration and haze pollution was observed across China, except in western regions where it's still promotional.
• Industrial co-agglomeration exhibits significant spatial spillover effects, initially promoting local haze but inhibiting it in surrounding areas.
• Urbanization and energy structure were identified as significant mediating factors in the relationship.

Conclusions:

• Industrial co-agglomeration's effect on haze pollution is complex and region-dependent.
• Policy interventions should consider spatial dynamics and mediating factors like urbanization and energy structure.
• The findings offer insights for mitigating haze pollution through strategic industrial planning.
