摘　　要：研究目的:在我国经济高质量发展进程中,交通路网通过提升运输效率、加快要素流动、增进地区经济联系不断推动产业结构优化升级。本文重点关注以铁路和公路为代表的交通路网密度与研发创新投入对产业结构升级的影响效应,并在此基础上提出有针对性的政策建议。研究结论:(1)交通路网所产生的时空压缩、经济集聚与知识溢出效应促进产业结构向高级化与合理化方向发展;(2)增大交通路网密度与研发创新投入是产业结构升级的重要渠道;(3)交通路网密度对产业结构升级的作用受产业结构发展阶段及地区经济发展水平的影响,东部地区的交通路网建设有利于产业结构向高级化发展,但却抑制了合理化升级;(4)本研究结论可为进一步增加交通路网密度及研发创新投入,推动产业结构向高级化和合理化方向发展提供参考借鉴。Research purposes:In the process of China's high-quality economic development,the traffic network constantly promotes the optimization and upgrading of industrial structure by improving transportation efficiency,accelerating the flow of factors and enhancing regional economic ties.This paper focuses on the influence of traffic network density and R&D innovation investment represented by railways and highways on industrial structure upgrading,and puts forward targeted policy suggestions on this basis.Research conclusions:(1)The space-time compression,economic agglomeration and knowledge spillover effects produced by the traffic network promote the advanced and rational development of industrial structure.(2)Increasing traffic network density and R&D innovation investment are important channels for upgrading industrial structure.(3)The effect of traffic network density on the upgrading of industrial structure is influenced by the development stage of industrial structure and the level of regional economic development.The construction of traffic network in the eastern region is conducive to the development of industrial structure to an advanced level,but it inhibits the rational upgrading.(4)The research conclusion can provide reference for further increasing traffic network density and R&D innovation investment,and promoting the development of industrial structure in the direction of upgrading and rationalization.
