集聚视角下知识密集型服务业对区域创新的影响研究

Impact of Knowledge Intensive Business Services on Regional Innovation from an Agglomeration View

基于2004—2010年的省际面板数据,运用知识生产函数理论框架分析了知识密集型服务业集聚对区域创新能力的影响,并通过引入交叉项对潜在的人力资本门槛效应进行了检验。结果表明,从产业集聚视角来看,知识密集型服务业对我国区域创新能力的促进作用不明显,受限于一定的人力资本水平,即存在门槛效应;但从城市空间集聚视角来看,知识密集型服务业已然表现出显著的创新促进作用。与此同时,两个视角下的区域层面都展现出明显的人力资本门槛效应并呈现出明显的区域差异。基于此,提出了相应的发展建议。

In this paper, we employ the theoretical framework of knowledge production function to analyse the im-pacts caused by KIBS on regional innovation capability based on the provincial panel data during the period of 2004 to 2010 in China. During this process, the human capital and its cross-term with KIBS are introduced to in-vestigate the potential threshold effect of human capital. The results show that, from the view of industrial agglom- eration, the impact of KIBS on regional innovative capability is not significant and conditional on a certain level of human capital. However, from the view of spatial agglomeration, KIBS are showing significant innovation-pro-moting. Meanwhile, from both of the views, there is an evidently threshold effect of human capital showing re-gional differences. Finally, we also proposed some policy suggestions.
