摘　　要：本文对企业进入对创新的影响进行理论和实证研究。理论部分,本文构建了一个企业进入综合影响创新的理论模型。新进入企业会对在位企业同时形成竞争所产生的负向“挤出效应”以及创新投入所产生的正向“溢出效应”,二者加总导致了企业进入与创新之间形成理论上的倒U型关系。忽视两种效应的综合作用可能会导致理论解释和政策适用产生偏误。实证部分,本文运用多种尽可能长时期的数据,对理论模型中提出的企业进入与创新之间的关系进行实证检验。在企业层面与行业层面,本文均发现行业进入率与企业创新之间存在显著而稳健的倒U型关系。基于此本文从如何促进实现“大众创业”与“万众创新”协同发展、促进中国创新水平提升角度提出政策建议。This paper studies the impact of firm entry on innovation theoretically and empirically.In the theoretical part,this paper constructs a theoretical model of how firm entry influences innovation.New entrants could have negative“crowding out effect”and positive“spillover effect”on incumbent firms,which result in the inverted-U relationship between firm entry and innovation.Ignoring the combined effects may lead to errors in theoretical interpretation and policy application.In the empirical part,this paper uses various data for as long a period as possible to empirically test the relationship between firm entry and innovation proposed in the theoretical model.At both the firm level and industry level,this paper finds a significant and robust inverted-U relationship between entry rate and firm innovation.This paper puts forward policy suggestions on how to promote the coordinated development of“mass entrepreneurship”and“mass innovation”and improve China's innovation capacity.
