报告题目：Catching the wind—Geography and knowledge Spillover: Evidence from patent citation and establishment of High-Speed Railway System in China

Abstract：This paper exploits exogenous variation in the construction of China’s High-Speed Railway (HSR) system to estimate the effect of reduction in transportation costs on the extent of geographical localization of knowledge spillovers in China. We show that connection to the HSR network leads to a 10% annual increase in the knowledge diffusion from a source (patent) to a beneficiary (city). The contribution of HSR connection is significantly positive even for cities located very faraway (within 3000km) from the source. However, the marginal benefit declines sharply over distance, with cities within 100 km enjoy the largest increase. We also show that peripheral cities—as opposed to metropolitan centers—experience significant improvement in innovation performance, possibly through the channel of enhanced spillover.  Thus, transportation infrastructure mitigates regional disparity in knowledge accumulation and innovation.
