国际移民、知识流动与知识生产跨国合作

International Migration,Knowledge Flows and Multinational Cooperation in Knowledge Production

本文从国际移民的角度探讨了国际知识流动与知识生产的跨国合作问题。本文构建了一个精简的知识生产模型并基于1990—2019年全球移民和专利引用数据进行了经验研究。基准结论表明,移民流出提升了目的国对本国专利的引用,即国际移民促进了知识的跨国流动。机制检验发现,当国家间默会知识交流障碍更大,或者作为默会知识载体的技能移民更多时,国际移民更能促进知识的流动。最后,本文识别了跨国合作专利,并发现国际移民促进了知识生产的跨国合作,并且当合作双方的发展程度差距较大时,这一促进效应会得到进一步增强。

We discuss on knowledge flows and transnational cooperation in knowledge production with the perspective of international migration.First,we build a theoretical framework on knowledge production and computes empirical evidences based on migration and patent citation data of 1990-2019.Baseline result shows that more patents been cited by destinations when migration increases,which means migration facilitates cross-border knowledge flows.Turn to mechanism,the result reveals that the effects in baseline get fur-ther enhanced when barriers to tacit knowledge communication are greater,or when there are more skilled migrants as carriers of tacit knowledge among international migrants.Finally,we identify multinational patents and find that international migration facilitates transnational cooperation in knowledge production,and this effect will get further enhanced when there is a greater gap in development between two countries.
