讲座内容摘要:
How did COVID-19 affect the innovation advantages of dense locations? Using data on the universe of U.S. patent applications, we find that the density premium in the production of novel inventions declined by 18.5%-22.9% in 2020-2021 relative to its pre-pandemic level. Smartphone data on local mobility suggest that the drop in the frequency of local interactions can explain a significant portion of this effect. While COVID-19 resulted in a temporary setback in the innovation advantages of dense locations, the role of urban density in facilitating the exchange and recombination of ideas is unlikely to be persistently replaced by online communication.
新冠肺炎疫情如何影响人口密集地区的创新优势?利用美国专利申请领域的数据,本文发现,2020-2021年,人口密集地区新的发明与创造比疫情前的水平下降了18.5%-22.9%。基于智能手机的人口流动数据表明,本地交互频率的下降可以解释这种影响的很大一部分。虽然新冠肺炎疫情导致人口密集地区的创新优势暂时受挫,但城市密度在促进思想交流和重组方面的作用不太可能持久地被在线交流所取代。
