基于地理效应的国际R&D溢出渠道再考察

Reexamination on Channels of International R&D Spillover Based on Geographic Effects

本文考察和比较了以跨国人口流动作为非嵌入式渠道与四种嵌入式渠道在国际R&D溢出中的作用。研究结果表明:移民作为一种非嵌入式渠道对国际R&D溢出地理范围具有决定性作用;人口流入和人口流出渠道对国际R&D溢出弹性的作用远大于贸易和FDI等嵌入式渠道的作用,而非嵌入式渠道与嵌入式渠道的交叉关系并没有一致性的结果。本文最后呼吁通过更为开放的人口流动政策促进国际R&D溢出效应。

Based on the study by Wang jianhua and Li Yanhong （2014）, this paper further investigates the population mobility as a disembodied channel of in- ternational R＆D spillover and compares it with four embodied channels in the previous study. The results show that the inflow of migrants serves as a funda- mental determinant of geographical scope of spillover and both inflow and out- flow of the population have greater effect on international spillover of R＆D than four embodied channels, and there is no consistent result on the crossing relation among them. Lastly, the paper calls on more open policy on population mobility to be made to promote the international R＆D spiUover.
