高技能工人从面对面的互动中获益。如果技术人员能够以更高的速度移动，那么知识传播和思想溢出就更有可能达到更远的距离。本文测量了与中国高速铁路（HSR）网络建设相关的知识创造后果，该网络连接了以全国最好的大学为特色的特大城市和二级城市。由于子弹头列车减少了跨城市的通勤时间，它们降低了在不同城市工作的技术工人之间面对面互动的成本。使用一个数据库，列出研究论文的出版物和引文，我们记录了知识生产和运输网络之间的互补效应。当通过高铁连接时，合作作者的生产力提高，新的合作作者对出现，更多高生产力的科学家迁移到高铁城市。
High skilled workers gain from face to face interactions. If the skilled can move at higher speeds, then knowledge diffusion and idea spillovers are more likely to reach greater distances. This paper measures the knowledge creation consequences associated with the construction of China's high speed rail (HSR) network that connects mega cities, that feature the nation's best universities, to secondary cities. Since bullet trains reduce cross-city commute times, they reduce the cost of face-to-face interactions between skilled workers who work in different cities. Using a database listing research paper publication and citations, we document a complementarily effect between knowledge production and the transportation network. When connected by the HSR, co-author productivity rises, new co-author pairs emerge and more highly productive scientists migrate to the HSR cities.
