摘要
以国家级城市群规划批复实施为准自然实验,基于2010—2022年794个省际行政边界区县面板数据,利用双重差分策略检验城市群一体化对边界地区减污与增长协同的影响。结果表明,国家级城市群规划实施明显促进和改善了边界地区经济增长和环境质量,该结论在一系列稳健性检验后依然成立,而且对位于优化提升类城市群和平原地区的边界地区作用效果更为显著。机制分析表明,国家级城市群规划主要通过发挥交通互通效应、金融融通效应和数字联通效应弱化地理条件限制,并通过技术创新带动效应、产业结构优化效应和区域环境协同治理效应弥补市场分割的不足,从而助力行政边界地区实现经济和环境双赢。研究结论有助于理解城市群一体化发展战略对新时代边界地区减污与增长协同发展的作用效果,可为新发展阶段统筹推进地区绿色发展,实现区域高质量发展和高水平保护提供启示。
Based on the panel data of 794 interprovincial administrative boundary counties from 2010 to 2022,this paper takes the approval and implementation of national-level urban agglomeration planning as a quasi-natural experiment,and employs a difference-in-differences(DID)strategy to examine the impact of urban agglomeration integration on pollution reduction and growth synergy in the boundary areas.The results show that the implementation of national-level urban agglomeration planning has significantly promoted and improved economic growth and environmental quality in peripheral regions.This conclusion remains valid after a series of robustness tests,with particularly pronounced effects observed in peripheral regions within optimized and upgraded urban agglomerations and plain areas.The mechanism analysis indicates that the planning of national-level urban agglomerations primarily weakens the limitations of geographical conditions through the effects of transportation connectivity,financial integration and digital interconnection.It also compensates for the deficiencies of market segmentation through the effects of technological innovation-driven growth,industrial structure optimization,and regional environmental co-governance,thereby contributing to a win-win situation in economic and environmental outcomes in the administrative boundary areas.These conclusions help to understand how the urban agglomeration integration strategy affects pollution reduction and growth synergy in border areas in the new era,offering insights for promoting regional green development and achieving high-quality development and high-level protection in the new development stage.
