摘　　要：本文利用2008—2018年的地市级高铁站点数据匹配上市公司研发数据,从地理同群效应的视角,研究高铁枢纽性对企业创新产出的影响及其中介机制。研究发现:第一,高铁枢纽性对企业创新产出的影响以抑制效应为主,且存在一定的效应动态性。第二,通过促进创新要素流动,高铁枢纽性增强了创新的地理同群效应,进而对企业创新产生了抑制作用。第三,非国有企业和小型企业更易受到高铁完善与同群效应导致的竞争压力减小的抑制效应的影响。第四,高铁枢纽性对企业创新产出的影响存在明显的空间梯度差异。在中部地区、非省会地区和经济欠发达地区,负向效应更显著,而在高创新城市则以促进作用为主。Based on the urban high‐speed rail sites data matching the R&D data of listed companies from 2008 to 2018,the impact of high‐speed rail hub on enterprise innovation output and its intermediary mechanism from the perspective of the geographical peer effect were empirically studied.The findings are as follows.First,the high‐speed rail hub has an inhibitory and dynamic effect on enterprises’innovation output.Second,by promoting the flow of innovative elements,high‐speed rail hub enhances the geographical peer effect in innovation,and hence restrains enterprises’innovation.Third,non‐state‐owned enterprises and small enterprises are more susceptible to the suppression effect because of the reduction of competitive pressure caused by the improvement of high‐speed rail and the peer effect.Fourth,there are obvious spatial gradient difference in the impact of high‐speed rail hubs on enterprises’innovation output.In the central region,non‐provincial capital cities and less‐developed areas,the negative impact is more significant,while the promotion effect is mainly in the innovative cities.
