高速铁路对城市群经济发展格局的影响及其作用机制

本文详细阐述了高铁开通对城市群发展的影响机理,以2005-2018年中国五大城市群92个地级市的数据为样本,从城市群视角出发,通过构建DID估计模型考察了高铁开通对经济发展格局的影响及其作用机制。研究发现：从整体城市群层面来看,高铁开通提升了五大城市群的经济增长水平,并缩小了城市群经济差距;从分城市群层面来看,高铁开通对每个城市群的经济增长均产生了正向效应,并显著地缩小了京津冀、长江三角和珠三角城市群的经济差距,有利于实现经济一体化;人才集聚、资本集聚、技术创新在高铁开通影响经济发展格局的过程中起着中介作用。

The influence of high-speed railway construction on the economic development pattern of urban agglomeration and its mechanism

This paper elaborates on the mechanism of the impact of the opening of high-speed rail on the development of urban agglomerations. Taking the data of 92 prefecture-level cities in China"s five major urban agglomerations from 2005 to 2018 as samples, and starting from the perspective of urban agglomerations, this paper investigates the impact of the opening of high-speed rail on the pattern of economic development and its mechanism by constructing DID estimation model. The research finds that: from the overall perspective of the five major urban agglomerations, the opening of high-speed railway has improved the economic growth level of the five major urban agglomerations, and narrowed the economic gap of urban agglomerations; The results of urban agglomeration show that the opening of high-speed railway has a positive effect on the economic growth of each urban agglomeration, and significantly reduces the economic gap between the Beijing-Tianjin-Hebei, Yangtze River Delta and Pearl River Delta urban agglomeration, which is conducive to the realization of economic integration. The concentration of talents, capital and technology innovation play an intermediary role in the process of the opening of high-speed railway affecting the pattern of economic development.
