摘要
利用县域高速铁路数据及微观企业产品数据,基于要素流动视角研究了县域高铁开通对企业出口产品质量的影响。机制分析表明:县域高铁开通促进了要素流动,进而通过管理效率提升效应、驱动研发创新效应和优质中间品匹配效应影响企业出口产品质量升级。异质性分析表明:对于管理效率高的企业、异质性产品和核心产品及距离中心城市较远的县域,高铁开通的质量升级效应更显著。
Utilizing data of operation of counties’high-speed railways and micro-enterprise products data in China,this study investigates the impact of opening of counties’high-speed railways on the export product quality from the perspective of factor mobility.Mechanism analysis indicates that the opening of county-level high-speed railways promotes factor mobility,and then affects the upgrading of export product quality in the Chinese enterprises through the enhancing management efficiency,driving R&D innovation,and the matching of high-quality intermediate products.Heterogeneity analysis reveals that for enterprises with higher management efficiency,heterogeneous products,core products,and those counties located at a greater distance from the central city,the quality upgrading effect of high-speed railways is more significant.
