摘　　要：2022年发布的《重庆都市圈发展规划》明确将四川广安纳入重庆都市圈,在打造高质量发展重要增长极同时,也将在省际交界地区一体化发展上先行先试、大胆探索。省际交界地区在区域协调发展中的问题和矛盾较为突出,由于边界两侧城市在行政归属上存在差异,地区间政策协调存在较高成本,不利于构建高效的区域合作机制,受到地方保护与市场分割影响,难以形成区域性统一市场。在上述因素共同作用下,省际交界地区陷入增长困境,成为区域经济发展的“洼地”。省际边界是否会阻碍省际交界地区经济发展?又借由何种影响机制发挥作用?理清上述问题,不仅能为建设跨省域都市圈提供有益参考,对实现共同富裕也具有重要意义。文章以1997年设立重庆直辖市为准自然实验,利用266个城市1993—2020年的面板数据,使用合成控制法构造反事实对照组,通过对比出现“重庆—四川”省际边界后实验组和反事实对照组经济发展路径的差异,评估省际边界的经济效应。研究结果表明:设立重庆直辖市后,位于“重庆—四川”交界城市的发展路径显著低于反事实对照组所反映的情形,进行安慰剂检验、稳健性检验以及排除竞争性假说后,文章的结论仍然成立,证明在其他条件不变情况下,位于省际交界地区的城市,其经济发展会受到来自省际边界的不利影响。进一步地,机制研究结果表明,省际边界会通过投资抑制效应、产业同质化效应和支出替代效应对省际交界地区的经济发展产生不利影响。在区域经济迈入一体化发展新阶段背景下,一方面要破除“行政区经济”下的隐性壁垒,加快建设全国统一大市场,为省际交界地区提供良好的发展环境,另一方面要积极推动机制体制创新,加速建立政府间协调和利益共享机制。结合文章的研究内容,建议在行政区与经济区适度分离、�The Chongqing Metropolitan Area Development Plan published in 2022 clearly includes-Sichuan Guang’an into the Chongqing Metropolitan Area,while creates an important growth pole for high-quality development,it will also take lead and boldly exploring the integrated development of inter-provincial border areas.Due to the differences in administrative affiliation of cities on both sides of the border,there are high costs of inter-regional policy coordination,which is not conducive to the construction of an efficient regional cooperation mechanism,and is affected by local protection and market segmentation,and it is difficult to form a regional unified market.Under the combined effect of the above factors,the inter-provincial border areas have fallen into growth difficulties and become“depressions”for regional economic development.The inter-provincial border is a typical area with prominent contradictions and problems in the development of regional economy.Will inter-provincial borders hinder economic development in inter-provincial border areas?And through what influence mechanisms do they work?To find out the causes of backward economic development in border areas and explore the mechanism of border’s influence on regional economy not only provide useful reference for the construction of cross-provincial metropolitan areas,but also have great significance for achieving common prosperity.For a long time in the past,competition rather than cooperation,segmentation rather than integration was the dominant strategy of local governments.Because the lower level of local governments could not directly influence the decision-making of the upper level of government,the border areas could only passively accept the adverse consequences brought by inter-provincial competition.From the perspective of government,differences in administrative ownership will increase the cost of coordination between governments,and it is difficult to form a regional cooperation mechanism of co-construction and sharing,which is not conduciv
