摘　　要：选取2007—2020年中国A股上市公司数据进行实证研究,结果表明,公共资本对企业创新具有显著促进作用,其中,公共教育资本的创新效应存在时滞性。在产业集聚的初级阶段,产业集聚程度越高,公共资本的创新效应越弱;在产业集聚的高级阶段,产业集聚程度越高,公共资本的创新效应越强。当私人资本投资小于某一特定值时,私人资本投资规模越大,公共资本的创新效应越强;当私人资本投资大于该特定值时,私人资本投资规模越大,公共资本的创新效应越弱。Based on the data of A-share listed companies from 2007 to 2020,the empirical research results show that public capital has a significant role in promoting enterprise innovation,and the innovation effect of public education capital has a time lag.In the initial stage of industrial agglomeration,the higher the degree of industrial agglomeration,the weaker the innovation effect of public capital;In the advanced stage of industrial agglomeration,the higher the degree of industrial agglomeration,the stronger the innovation effect of public capital.When private capital investment is less than a certain value,the larger the scale of private capital investment,the stronger the innovation effect of public capital.When private capital investment is greater than the specified value,the larger the scale of private capital investment,the weaker the innovation effect of public capital.
