【摘要】 创新作为引领发展的第一动力成为我国经济由高速度发展向高质量转变的必然要求,我国区域创新体系建设在“十三五”时期已取得阶段性成效,但还存在区域创新发展不平衡、部分区域创新平台发展水平不高、创新要素流动不充分等问题。高速铁路作为交通设施质量的重要提升,在解决大通道上旅客运输问题上发挥了重要作用,由此引发的要素流动带动了隐性知识的传播和共享,为解决我国在区域创新发展过程中遇到的问题提供了新思路。在这一背景下,探究高速铁路对区域创新的影响,有利于推动高铁与城市创新协同发展。本文对高铁的创新效应和门槛效应进行了理论分析和实证检验。在理论上,基于对我国高铁和区域创新现状的分析,应用区域创新系统理论、新经济地理理论、知识溢出理论和门槛效应理论分析了高铁的对区域创新产生影响的原因及其作用机制。在实证上,本文基于2003-2019年全国268个地级市的面板数据,首先用多时点DID模型研究了全国范围内高铁对区域创新的促进作用,并对结果进行了安慰剂检验和逐年PSM-DID检验;其次,进一步探究了关于城市群的异质性问题;再者,选取教育资源水平和政府支持力度作为门槛变量,利用门槛模型探究了高铁对区域创新的门槛效应。结果表明:(1)高铁的开通运营明显地促进了沿线城市区域创新能力提升;(2)高铁开通显著影响区域创新格局向两极化发展:高铁抑制非城市群城市的区域创新增长,而促进城市群城市的区域创新增长,说明高铁对区域创新的影响存在关于区位创新环境的门槛效应,其开通运营促进了区域创新向城市群聚集,使区域创新格局呈两极化发展;(3)高铁对区域创新的影响存在关于教育资源水平和政府支持力度的双重门槛效应,其中教育资源水平与该影响系数之间呈“正几”字形关系,政府支持力度与该影响系数之间呈“倒几”字形关系,当创新区域的教育资源水平在0.23%和0.46%之间,政府支持力度小于1.387时,高铁对区域创新起到更加显著的正向影响。为进一步充分发挥高铁和区域创新的联动效应,促进经济社会健康发展,本文结合研究结论提出了以下建议:(1)调整和完善教育资源水平分布,助力更多城市突破第一门槛;(2)保持适当的政府支持,引入多元化融资渠道共同发展;(3)关注城市综合交通枢纽建设,促进高铁与城市轨道交通融合发展。更多还原

【Abstract】 Innovation as the first driving force for development has become an inevitable requirement for China’s economy to transform from high-speed development to highquality.The construction of China’s regional innovation system has achieved phased results during the "13th Five-Year Plan" period,but there are still imbalances in regional innovation and development.The development level of innovation platforms in some regions is not high,and the flow of innovation elements is insufficient.As an important improvement in the quality of transportation facilities,high-speed railways have played an important role in solving the problem of passenger transportation on large corridors.The flow of factors caused by this has led to the dissemination and sharing of tacit knowledge,which is a great way to solve China’s problems in the process of regional innovation and development.In this context,exploring the impact of high-speed rail on regional innovation is conducive to promoting the coordinated development of highspeed rail and urban innovation.This paper conducts a theoretical analysis and empirical test on the innovation effect and threshold effect of high-speed rail.In theory,based on the analysis of the current situation of high-speed rail and regional innovation in my country,the reasons and mechanism of the impact of high-speed rail on regional innovation are analyzed by applying regional innovation system theory,new economic geography theory,knowledge spillover theory and threshold effect theory.Empirically,based on the panel data of 268prefecture-level cities in China from 2003 to 2019,this paper firstly studies the effect of high-speed rail on Regional Innovation in the whole country using the multi-time point DID model,and conducts placebo and PSM-DID tests on the results year by year.Secondly,it further explores the heterogeneity of high-speed rail regional innovation on urban clusters.Furthermore,this paper selects the level of educational resources and government support as threshold variables,and uses the threshold model to explore the threshold effect of high-speed rail on regional innovation.The results show that:(1)the opening and operation of high-speed rail has significantly promoted the regional innovation capability of cities along the line;(2)The opening of high-speed railways significantly affects the polarization of regional innovation pattern: high-speed railways inhibit the growth of regional innovation in nonurban agglomeration cities and promote the growth of regional innovation in urban agglomeration cities.This indicates that the high-speed rail has threshold effect on regional innovation environment,and it promotes regional innovation to cluster into urban clusters and polarizes the regional innovation pattern.(3)The impact of high-speed rail on regional innovation has a double threshold effect on the level of educational resources and government support,in which the level of educational resources and the influence coefficient is in the shape of "plow-high-low",and those between the level of government support and the influence coefficient is in the shape of "high-low-high".When the level of educational resources in the innovation area is between 0.23% and0.46%,and the government support is less than 1.387,the high-speed rail has a more significant positive impact on regional innovation.In order to further give full play to the linkage effect of high-speed rail and regional innovation and promote the healthy development of economy and society,this paper puts forward the following suggestions based on the research conclusions:(1)Adjust and improve the level distribution of educational resources to help more cities break through the first threshold;(2)Maintain appropriate government support and introduce diversified financing channels for common development;(3)Pay attention to the construction of urban comprehensive transportation hubs and promote the integrated development of high-speed rail and urban rail transit.更多还原
