国际间技术溢出对我国自主创新的动态效应分析——兼论人力资本的消化吸收

基于变参数的状态空间模型,本文分析了不同研发资本及人力资本对中国自主创新能力提升的动态效应,并运用中国1985～2006年的数据对其进行了实证检验。研究结果表明中国自主创新能力的提升主要依靠本国研发投入;FDI溢出的国外研发时我国自主创新能力的提升起到促进作用,并有上升趋势。进口贸易和国外专利申请却对我国的自主创新起到阻碍作用,但这种阻障作用近年来有所缓和;人力资本尚未跨越FDI溢出渠道所需东道国知识水平能达到的最低"门槛"。

The Dynamic Effect of International Technical Spillover on China Innovation:with Discussion of the Absorptive Effects of Human Capital

Based on the state space equation of time-varying parameter model,this paper empirically analyzes the effects 9f different R&D capitals,human capital on independent innovation with 1990～2005 data.The results show that China innovation ability mainly depends on domestic R&D input,but its utility has the downtrend in recent years;Foreign R&D through FDI stimulate the innovation of China,and the effect raise slowly recently;import trade and applications for patents received from foreign country block the upgrade of innovation,but the effect of hindrance is descending recently;human capital doesnt get the lowest threshold which is needed in host country by technical diffusion through FDI.
