R&D投入与区域创新能力关系及溢出效应分析

基于空间溢出效应，以传统Cobb-Douglas生产函数为研究框架，引入R&D投入作为新生产要素，将金融发展作为调节变量，利用计量经济学空间杜宾模型对我国内地30个省份2006-2015年R&D投入和区域创新能力溢出效应进行研究。结果显示，以金融发展为调节变量，R&D投入对区域创新能力提升具有显著促进作用，区域创新能力存在溢出效应;同时，在金融系统发展支持下，R&D人员投入溢出效应对区域创新能力起消极作用，而R&D资金投入溢出效应对区域创新能力具有促进作用。因此，加快金融系统发展，对金融资产进行合理有效配置，构建由政府发挥引导作用的金融体系，对R&D投入和区域创新能力提升具有重大意义。

Analysis of the Relationship and Spillover Effect between R&D Input and Regional Innovation Capability

Based on the Spatial Spillover Effect, the thesis uses the research framework of traditional Cobb-Douglas production function and Introduces R&D input as a new factor of production. Furthermore, it selects financial support as a moderator variable. At last, this thesis uses the spatial Durbin model coming from Econometrics to do research on the spillover effect of R&D input and regional innovation capacity of 30 provinces in China in the past 9 years. The results shows that R&D input has a positive effect on regional innovation capability and regional innovation capability has obvious spillover effect under the moderating effect of financial support. At the same time, the spillover effect of R&D personnel input has a negative effect on regional innovation capability in financial system development support. On the contrary, the spillover effect of R&D capital input has a positive effect on regional innovation capability in financial system development support.
