摘要
本文基于2003~2018年285个地级及以上城市面板数据,使用双向固定效应双重差分模型进行实证分析,研究高铁开通对区域经济一体化产生的影响及作用机制。研究发现:高铁开通显著促进了区域经济一体化,并且通达性成为高铁影响区域经济一体化的重要中介。本研究有助于更加全面地评价高铁对区域经济一体化产生的影响,未来应该继续完善高铁网络布局,进一步促进区域经济一体化,加快高铁网络下经济空间格局的优化。
Based on the panel data of 285 cities at prefecture level and above from 2003 to 2018,this paper uses the two⁃way fixed effect DID method for empirical analysis to study the impact of high⁃speed rail on regional economic integration and its mechanism.The results show that:The opening of high⁃speed rail significantly promotes regional economic integration,and accessibility has become an important mechanism for high⁃speed rail to affect regional economic integration.Through this study,it is helpful to more comprehensively evaluate the impact of high⁃speed rail on regional economic integration.In the future,we should continue to improve the layout of high⁃speed rail network,further promote regional economic integration,and accelerate the optimization of economic spatial pattern under the high⁃speed rail network.
