Abstract

ABSTRACT Population mobility plays an essential role in the diffusion of knowledge. To the best of our knowledge, the existing literature focuses on the migration of workers between regions. Still, we employ a temporary policy of human mobility restriction in China to estimate the effect of COVID-19 on innovation. We find that the number of application invention patents decreases remarkably 1.813 using RD design and remains declined even if we rule out the Spring Festival and the viral effects using RD-DID. Moreover, the mechanism research suggests that the lockdown causes a decline in the population mobility within Wuhan city and inflow from other cities and we rule out the mechanism that skilled labours flow out Wuhan. In addition, we further find that institutional innovations have a significant reduction, especially invention patents in universities. This study highlights the enormous negative impact of human mobility restrictions on innovation due to COVID-19.

人员流动限制与创新:来自中国的证据

人口流动在知识传播中起着至关重要的作用。据我们所知，现有文献关注的是工人在地区之间的迁移。尽管如此，我们还是采用了中国限制人员流动的临时政策来估计新冠肺炎对创新的影响。我们发现，使用RD设计的申请发明专利数量显著减少了1.813，即使排除了春节和使用RD-DID的病毒效应，申请发明专利的数量仍在下降。此外，机制研究表明，封锁导致武汉市内人口流动和其他城市人口流入下降，我们排除了技术劳动力流出武汉的机制。此外，我们进一步发现，制度创新显著减少，尤其是大学的发明专利。这项研究强调了新冠肺炎对人类流动限制对创新的巨大负面影响。

期刊介绍： Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance. Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
