【摘 要】This paper studies how high-speed railway (HSR) connections in China affect local innovation. Exploiting the plausible exogenous variation in HSR connection caused by the staggered introduction of HSR stations in China, we find that HSR connection has a positive effect on local innovation. By adopting natural language processing techniques, we construct the measures of breakthroughness of local innovation based on patent abstracts and claims. We show that the HSR connection promotes incremental innovation, as measured by both within-city and cross-city patent text similarity, while it fails to facilitate radical innovation. Moreover, we find that the HSR connection affects the breakthroughness of local innovation mainly through knowledge spillovers, as incremental innovation mainly exploits existing knowledge, while breakthrough innovation relies on the exploration of unknown knowledge. The introduction of HSR connection brings more cross-city collaborations, patent citations, and patent transactions, which are the main channels through which HSR connection affects cross-city patent text similarity.
