Abstract

Geographical distance constitutes friction in searching for research collaborators. Taking advantage of a quasinatural experiment featured by High-Speed Railway (HSR) lines in China, this paper employs the difference-in-differences model to identify the causal impact of a substantial improvement in the intercity transportation infrastructure on collaborative innovation across cities. The data pertain to a universe of patent applications filed by Chinese universities and their citations. We find that HSR contributes to a substantial increase in the innovation quantity and quality of collaborative patenting innovation between universities and corporates. It contributes to industry collaboration by utilizing university academic disciplines in the related technology fields. Lastly, HSR facilitates universities to search for new research partners with better quality beyond the geographical boundary.

跨界研究合作:来自中国大学专利的证据
地理距离构成了寻找研究合作者的摩擦。利用中国高铁线路的准自然实验,本文采用差异中的差异模型来确定城际交通基础设施的大幅改善对城市间协同创新的因果影响。这些数据涉及中国大学提交的大量专利申请及其引文。我们发现,高铁有助于大幅提高大学和企业之间合作专利创新的数量和质量。它利用相关技术领域的大学学术学科,为行业合作做出贡献。最后,高铁有助于大学在地理边界之外寻找质量更好的新研究合作伙伴。

期刊介绍: The Journal of Regional Science (JRS) publishes original analytical research at the intersection of economics and quantitative geography. Since 1958, the JRS has published leading contributions to urban and regional thought including rigorous methodological contributions and seminal theoretical pieces. The JRS is one of the most highly cited journals in urban and regional research, planning, geography, and the environment. The JRS publishes work that advances our understanding of the geographic dimensions of urban and regional economies, human settlements, and policies related to cities and regions.
