Cleaner Skies Across Borders: The Impact of Centralized Air Monitoring in China University of Birmingham, United Kingdom This study investigates the impacts of centralized monitoring on cross-border air pollution in China, utilizing the county-level satellite-derived PM2.5 data from 2013 to 2019. Taking the centralization of air monitoring as a quasi-experiment, we employ a difference- in-difference-in-differences (DDD) approach to assess changes in air pollution levels in boundary counties following this intervention. Our results show a significant reduction in boundary air pollution, with PM2.5 concentrations in border counties decreasing by 4 per- cent (equivalent to 2,443μg/m3). The effect is more pronounced in border counties in the eastern provinces, municipalities, and industrially intensive areas. Mechanism analysis indicates that centralized air monitoring reduces the strategic distribution of industrial firms near provincial borders and enhances the enforcement of environmental regulations, as evidenced by an increase in the number of penalty cases of environmental violation. These findings underscore the effectiveness of centralized monitoring in mitigating cross-border air pollution and highlight the critical role in strengthening regulatory frameworks in the context of environmental governance. | |
