政府支持对KIBS企业研发投入的影响研究

Study on influences of government support on R&D investment to KIBS Firms

通过构建政府和KIBS企业动态博弈模型,从理论上探讨政府支持对企业研发投入的可能影响,并使用上市公司面板数据和差分GMM方法进行实证检验。研究结果发现:政府补贴对KIBS企业研发投入具有正向影响,但存在着一定程度的低效率;知识产权保护水平对KIBS企业研发投入具有正向影响,公共信息服务对企业研发投入具有负向影响,但上述结果在统计上均不显著;政府补贴与知识产权保护水平和公共信息服务之间存在着比较显著的互补效应,其组合对KIBS企业研发投入的正向综合影响明显增强。

This paper has established a dynamic game model between government and Knowledge Intensive Business Service( KIBS) firms. Then the effects of government support on KIBS firms are discussed theoretically. And empirical tests are carried out though difference-GMM method with panel data of KIBS listed companies. According to the research results,government subsidy has positive impacts on research and development investment of KIBS firms and there is a certain degree of inefficiency.The level of intellectual property rights protection has positive impacts on research and development investment of KIBS firms and public information service has only negative impacts,which are both statistically insignificant. There are obvious complementary effects between government subsidy and the level of intellectual property rights protection and public information service,which obviously become much stronger.
