Research on the Impact of Atmospheric Self-Purification Capacity on Environmental Pollution: Based on the Threshold Effect of Environmental Regulation

In China, Hebei Province and Guangdong have many pollution-intensive industries; yet suffers more serious atmospheric or environmental pollution than Guangdong. To explain the phenomenon, this paper chooses statistical data of 286 prefecture-level cities in Chinese mainland from 2005 to 2018 empirically tests spatial effect threshold characteristics self-purification capacity on by using autoregression model (SAR), Durbin (SDM), panel model. As evinced, local has a significant inhibitory pollution, absolute value direct coefficient reaches 1.337. Simultaneously, pollution. The regulation as variable is 11.6349. This means that when level proves higher 11.6349, it attenuates heterogeneity research unveils, capacities various regions form correlation with suggests governments should strengthen construct an inter-regional joint prevention control system for atmospheric-pollution governance enhance capacity.
