Abstract
© 2019 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 complementarity 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.
