摘要
利用2008—2020年的中国高铁列车时刻表数据构建加权高铁网络模型,并采用复杂网络分析法得到高铁网络节点城市的网络优势,进而运用双向固定效应模型考察了高铁网络优势对上市公司全要素生产率的影响。研究发现:中国高铁网络优势在逐年提升,然而不同等级城市之间的网络优势差距在逐渐扩大;高铁网络优势会显著并且持续地促进本地上市公司全要素生产率的提升,其中节点城市的连通性和访问性对上市公司全要素生产率的提升程度较大;高铁网络优势对全局性节点城市、东部城市群、交流密集型行业、市场主导型服务业、小规模企业和距离高铁站30km以内的企业生产率拉动作用更为明显;高铁网络优势在供给侧方面通过促进企业人力资本集聚、缓解融资约束来提升企业生产率,在需求侧方面通过扩大市场潜能来提升企业生产率。研究结论为构建中国高铁网络以及促进中国经济高质量发展提供了理论和经验上的支持。
This paper constructs a weighted high-speed rail network model based on Chinese high-speed rail train schedule data from 2008 to 2020,uses complex network analysis to obtain the network advantages of high-speed rail network node cities,and utilizes the two-way fixed effects model to examine the impact of high-speed rail network advantages on the total factor productivity of listed companies.The analysis reveals several important findings.First,the network advantages of Chinese high-speed rail are increasing yearly;however,the gap in network advantages between cities at different levels is gradually widening.Second,the network advantages of high-speed rail will significantly and continuously promote the improvement of the total factor productivity of local listed companies,with the connectivity and accessibility of the node cities having a great impact on companies'total factor productivity.Third,the network advantages of high-speed rail have a more pronounced effect on enterprise productivity in global node cities,eastern urban agglomerations,communication-intensive industries,market-oriented service industries,small-scale enterprises,and enterprises within 30km of a high-speed rail station.Finally,the network advantages of high-speed rail can improve enterprise productivity by promoting human capital agglomeration and easing financing constraints on the supply side and expanding market potential on the demand side.Therefore,this study provides theoretical and empirical support for high-speed rail network construction and high-quality economic development in China.
