Abstract
How does transport infrastructure spur innovation? This article examines the knowledge spillover effects of the construction of high-speed railways (HSR) in China. Using a database listing patent application information and Chinese city samples over the period 2005-2015, we find that the connection to HSR networks significantly increases the number of patents at the city level. Moreover, our results show that more collaborative or radical innovations and those operating in technologically complex industries benefit more from HSR. Our findings extend prior work on transport infrastructure and the literature on the geography of innovation and provide a comprehensive understanding of how various innovation outcomes benefit in different ways from reduced travel costs.
