区域一体化何以促进边界地区减污降碳协同治理
How does Regional Integration Promote Synergistic Pollution and Carbon Reduction in Border Regions?
摘要
Abstract
Boundary pollution presents a highly complex challenge and has become a critical issue for achie-ving synergistic pollution and carbon reduction.This paper treats the approval and establishment of national urban agglomerations as a quasi-natural experiment,using whether a city is located on a provincial boundary to define boundary areas.It examines the mechanisms and effects of regional integration on urban governance of pollution and carbon emissions,providing both theoretical insights and practical references for addressing the pollution lowland problem and enhancing synergistic environmental outcomes. This paper employs panel data from 282 prefecture-level cities from 2003 to 2022 and applies a multi-period difference-in-differences method to evaluate the impact of national urban agglomeration construction on synergistic pollution and carbon reduction in provincial boundary cities.The results show that regional integration policies ef-fectively alleviate governance fragmentation and pollution spillovers in boundary areas,significantly enhancing the level of synergistic pollution and carbon reduction.This conclusion remains robust after a series of tests,including indicator adjustment,alternative dependent variables,and sample exclusions of municipalities,provincial capitals,and competing policies.The long-term effect analysis reveals that the impact of regional integration accumulates o-ver time but gradually weakens.Heterogeneity analysis reveals that the synergistic governance effect is more pro-nounced in boundary areas of the eastern and central regions,as well as in peripheral regions adjacent to urban ag-glomerations,while it is significant but weaker in boundary areas within urban agglomerations and remains insignifi-cant in the western region.Mechanism analysis indicates that regional integration promotes synergistic pollution and carbon reduction through two primary channels.On one hand,it strengthens coordinated environmental enforcement and regulatory intensity,reducing opportunities for regulatory arbitrage across jurisdictions.On the other hand,it facilitates the diffusion of green technologies and stimulates green innovation,thereby enhancing the endogenous ca-pacity for environmental improvement.However,the effectiveness of these mechanisms is constrained by fiscal pressure faced by local governments and by persistent market segmentation. The marginal contributions of this study are threefold.First,it integrates regional integration with boundary environmental governance,thereby extending the spatial dimension of regional environmental governance research.Second,it incorporates green technological innovation,coordinated environmental regulation,fiscal pressure,and market segmentation into a unified analytical framework,clarifying both institutional and market-based mechanisms through which regional integration affects boundary areas.Third,it proposes targeted policy implications for strengthening cross-regional cooperation to effectively address the boundary pollution lowland problem.关键词
