摘　　要：构建基于二元“城市对”的空间尺度,利用“宽带中国”政策冲击,实证检验互联网基础设施连通对城市群市场一体化的影响效应。研究表明:互联网基础设施连通能有效提高城市群内部的市场一体化水平,这种市场一体化效应主要通过缓解行政分割来实现。然而,不同城市群间的地方政府缺乏制度化的协作关系,相互合作的内生动力不足,导致了城市群之间存在政绩障碍和产业功能障碍。这些障碍限制了互联网基础设施对跨城市群市场整合的作用。研究结论有助于理解互联网基础设施对城市群一体化的复杂影响,对促进全国统一大市场建设以及探索数字经济下区域发展新模式具有重要意义。The paper constructs a spatial scale based on dual“city pairs”,and empirically tests the impact of internet infrastructure connectivity on the market integration of urban agglomerations by using the impact of“broadband China”policy.Results show that internet infrastructure connectivity can effectively increase the level of market integration within city clusters.This market integration effect is mainly realized by alleviating administrative fragmentation.However,the lack of institutionalized collaboration among local governments and the lack of endogenous motivation for mutual cooperation among different city clusters have led to the existence of performance barriers and industrial functional barriers among different city clusters.These barriers limit the market integration of internet infrastructure across city clusters.The findings help to understand the complex impact of internet infrastructure on the integration of urban agglomerations,and are of great significance in promoting the construction of a unified national market and exploring a new model of regional development under the digital economy.
