摘要
笔者分析了外部知识进入和本地知识多样性影响地区创新能力的作用机制,并进一步讨论了不同多样性类型的影响。实证结果表明:我国技术创新主要源于国内研发资金投入;外部技术知识影响主要通过国际贸易发挥作用,存在比较显著的正效应;知识多样性从整体而言对地区创新能力有促进作用,其中本地知识关联多样性相对于非关联多样性,有更加明显的正效应。
In this paper,the authors analyzed the mechanism of how external knowledge and the diversity of regional knowledge impact the regional innovation and discussed the influence of different types of knowledge diversity by the way of GMM with dynamic panel data during 2000- 2011. The empirical results show that the technology innovation is mainly pushed by the domestic RD investments. The influence of external knowledge is mainly through international trade,and there is a significant positive effect. The diversity of knowledge stimulates the innovation as a whole,and the correlated diversity of the knowledge has an obvious positive influence than the uncorrelated diversity.
