摘要
通过剖析ICT(信息和通信技术)影响区域创新效率的作用机制,并结合2009~2018年的面板数据(1),揭示ICT对区域创新效率的直接影响、间接影响以及对不同地区、不同创新主体之间的差异。结果显示:ICT对我国区域创新效率的提升具有明显的驱动作用,且对中西部地区的溢出强度高于东部地区;对于不同的创新主体,ICT的创新溢出效应存在高校大于科研机构大于企业的异质性特征;ICT可以通过人力资本、金融发展和产业升级的中介作用间接促进区域创新效率水平提高,但ICT创新溢出的间接效应小于直接效应。
By analyzing the mechanism of ICT influence on regional innovation efficiency,and combining the panel data of China from 2009 to 2018,this paper empirically tests the direct and indirect effects of ICT on regional innovation efficiency and the differences between different regions and different innovation systems.Results show that,ICT has an obvious driving effect on the improvement of regional innovation efficiency in China,and the boosting effect of ICT on regional innovation in the central and western regions is greater than that in the eastern region.For different innovation systems,the innovation spillover effect of ICT is heterogeneous in that universities are larger than scientific research institutions and larger than enterprises.ICT can indirectly promote the improvement of regional innovation efficiency through the intermediary of human capital,financial development and industrial upgrading.However,the indirect effect of ICT innovation spillover is smaller than the direct effect.
