高铁与城市经济高质量发展——基于地级市数据的实证研究

High Speed Rail and High-Quality Development of Urban Economy:An Empirical Study Based on the Data of Prefecture-Level Cities

基于2005—2016年中国282个地级以上城市数据,从创新、协调、绿色、开放和共享五个维度构建城市经济高质量发展评价指标体系,并运用双重差分(DID)方法的研究表明,高铁开通显著提升了沿线城市经济高质量发展水平,在长期内这种促进作用主要体现在创新和协调两个内涵维度上。异质性分析表明,高铁开通对于大城市和省会城市经济高质量发展的推动效应最强,而对中小城市和非省会城市效果不明显。影响机制分析表明,创业活跃度、产业结构的合理化以及产业结构高度化对高铁开通城市的质量型增长具有显著促进作用。

Based on the data of 282 prefecture-level cities in China from 2005 to 2016,this paper constructs an evaluation index system of high-quality development of urban economy from the five dimensions of innovation,coordination,greenness,openness and sharing.The findings of the study that employs the difference-in-differences method show that the opening to traffic of high-speed rails has significantly improved the level of high-quality economic development of the cities along the railways.In the long-term,this role is mainly reflected in the two connotative dimensions of innovation and coordination.The heterogeneity analysis demonstrates that the opening of high-speed rails has the stronger promoting effect on the high-quality economic development of large cities and provincial capital cities,but has no obvious effect on small and medium-sized cities and non-provincial capital cities.The analysis of the affecting mechanism indicates that the entrepreneurial activity,the rationalization of industrial structure and the industrial structure supererogation have a significant promoting effect on the quality-oriented growth of cities with high-speed rails.
