撤县设区、交通碳减排与城市绿色治理
County-to-District Conversion,Transportation Carbon Emission Reduction,and Urban Green Governance
摘要
Abstract
Against the backdrop of intensifying global climate change challenges and the guidance of China's"carbon peaking and carbon neutrality"strategic goals,the green and low-carbon transformation of transportation plays a crucial role in urban green governance and the achievement of national emission reduction targets.Based on the county-level panel data in China from 2011 to 2023,a difference-in-differences model was constructed to explore the impact of the county-to-district conversion policy on transportation carbon emission reduction and its mechanism,and a heterogeneity analysis was conducted from the aspects of geographical location,national-level urban agglomerations,and environmental regulations.The results show that:① The county-to-district conversion achieves the spatial unification of governance power and significantly promotes transportation carbon emission reduction,with a more prominent role in the eastern region,non-national-level urban agglomerations,and key environmental protection cities.② Mechanism analysis finds that the county-to-district conversion can reduce transportation carbon emissions by improving traffic accessibility,promoting green technological innovation,and driving industrial structure upgrading.③ The county-to-district conversion also exhibits a significant positive spatial spillover effect on transportation carbon emissions,showing the characteristic of"local emission reduction and neighboring emission increase".关键词
