农村电商发展对县域碳减排和大气污染物减排的影响研究OACHSSCD

Based on panel data from 1662 counties in China from 2007 to 2021,this study constructs a quasi-natural experiment leveraging the national rural e-commerce comprehensive demonstration policy.Employing a staggered difference-in-differences(DID)model,it systematically investigates the impact of rural e-commerce development on county-level carbon and air pollutant reductions.The findings indicate that rural e-commerce development significantly curbs county-level CO2 and PM2.5 emissions,injecting strong momentum into achieving county-level"dual carbon"goals and improving ambient air quality.Furthermore,it fosters a positive synergy between carbon and air pollutant reduction,laying a solid foundation for realizing coordinated pollution and carbon reduction governance and synergistic efficiency gains.Mechanism analysis reveals that rural e-commerce development effectively suppresses CO2 and PM2.5 emissions and enhances their synergistic governance by elevating the level of county-level informa-tization development and promoting the optimization and upgrading of industrial structures.Heterogenei-ty analysis demonstrates that the inhibitory effects of rural e-commerce development on CO2 and PM2.5 e-missions are more pronounced in counties located in the western region,with higher levels of economic development,and with stricter environmental regulations.In light of these findings,efforts should be made to fully unleash the enabling effect of rural e-commerce on ecological environmental protection and strengthen its synergy for pollution and carbon reduction,thereby providing crucial support for county-level ecological civilization construction and high-quality development.
