Trains of Thought: High-Speed Rail and Innovation in China Tsiachtsiras, Georgios Moreno Serrano, Rosina Miguélez, Ernest Trens d'alta velocitat Innovacions tecnològiques Patents d'invenció High speed trains Technological innovations Patents This paper explores the effect of the High Speed Rail (HSR) network expansion on local innovation in China during the period 2008-2016. Using exogenous variation arising from a novel instrument - courier’s stations during the Ming dynasty, we find sòlid evidence that the opening of a HSR station increases cities’ innovation activity. We also explore the role of inter-city Technology diffusion as being behind the surge of local innovation. To do it, we compute least-cost paths between city-pairs, over time, based on the opening and speed of each HSR line, and obtain that an increase in a city’s connectivity to other cities specialized in a specific technological field, through the HSR network, increases the probability for the city to specialize in that same technological field. We interpret it as evidence of knowledge diffusion. 2022-12-22T10:53:43Z 2022-12-22T10:53:43Z 2022 info:eu-repo/semantics/workingPaper https://hdl.handle.net/2445/191733 eng Reproducció del document publicat a: https://www.ub.edu/irea/working_papers/2022/202220.pdf IREA – Working Papers, 2022, IR22/20 AQR – Working Papers, 2022, IR22/10 [WP E-IR22/20] [WP E-AQR22/10] cc-by-nc-nd, (c) Tsiachtsiras et al., 2022 http://creativecommons.org/licenses/by-nc-nd/3.0/es/ info:eu-repo/semantics/openAccess 61 p. application/pdf Universitat de Barcelona.
