Abstract
- Based on the panel data of 255 cities in China, this study built a spatial Durbin model to study the impact of China's industrialization on the PM <subscript>2.5</subscript> pollution level. Meanwhile, an environmental governance tool characterized by forest and grass coverage was introduced to explore the internal mechanism and exogenous driving force of EKC. The results show that ① the relationship between industrialization and PM <subscript>2.5</subscript> concentration is obviously an inverted u-shaped, and the EKC hypothesis was verified. ② The formation of the EKC curve was caused by the external factors and not the endogenous mechanism of economic growth. Forest-grass coverage plays a regulating role in the relationship between industrialization and PM <subscript>2.5</subscript> pollution level, namely the inverted u-shaped structure of environmental EKC results from environmental governance tool with forest and grass cover rather than the automatic adjustment of economic growth. ③ The influence of industrialization on PM <subscript>2.5</subscript> concentration has a spatial spillover effect. Urban industrialization not only affects the PM <subscript>2.5</subscript> concentration in local regions but also its neighboring region.
