基础设施建设打破了国内市场分割吗?

Does Infrastructure Construction Break up Domestic Market Segmentation?

从理论上来说,作为社会先行资本的基础设施建设一定程度上有助于打破国内市场分割,为构建现代市场体系奠定基础。本文基于新经济地理学理论,利用1993—2012年我国省际面板数据,采用空间面板杜宾模型对我国基础设施建设与市场分割的关系进行研究分析。实证结果表明,"以邻为壑"现象在中国仍长期存在;基础设施建设作为打破市场分割的物质基础,可为政府加强基础设施建设提供理论支撑;基础设施建设的空间溢出效应呈现出阶段性差异;不同区域或不同区位下市场分割的策略性行为并非一致。基于此,政府应加强基础设施建设,缩小基础设施建设的区域差异;同时,加强投资主体的跨区域协作,削弱地理界限对市场的不利影响;此外,政府应积极打造现代服务型政府,充分发挥政策导向功能,避免人为过多干预市场秩序,进而实现市场在资源配置中发挥决定性作用,以期建立现代市场体系。

Summary： Since 1978, China＇s economy has developed rapidly due to the inspiring enthusiasm and creativity of laborers, the reform and opening-up policy, the release of institutional dividends, and especially the positive role the market mechanism has played in resource allocation. Historical experience has shown that the market mechanism functions to integrate and unify markets rather than scattering and isolating them. A unified domestic market can fully promote market competition, bring about economies of scale and normalize market rules, guaranteeing the free flow of limited resources to the most efficient sectors. Therefore, breaking up market segmentation and accelerating the establishment of a modern market system have become major practical problems in the development of China＇s market economy. In general, the tendency to unite the domestic market has been a gradual historical process.
