摘　　要：基础研究创新关乎国家经济增长内生动力,如何推动基础研究创新是中国式现代化进程中迫切需要回答的问题。本文以地铁开通为准自然实验,使用双重差分模型研究本地交流成本降低对高校基础研究创新的影响及作用机制。本文收集了2006~2020年中国高校分学科的基础研究产出指标,实证研究发现地铁开通使得该城市对应高校学科层面的基础研究产出显著提升了约4%,动态效应表明这一效果随着时间的推移在逐步强化。机制分析表明,城市地铁通过降低本地交流成本促进学术交流和科学合作,最终提升了基础研究产出。在进行一系列稳健性检验后,本文的结果依然稳健。本文的研究为推动高校基础研究创新提供了参考,也为理解交通强国产生的创新效应提供了独特的视角。As the source of science,basic research plays a decisive role in improving a country's overall innovation level and solving key technological problems.Promoting innovation in basic research is crucial for the endogenous driving force of a country's economic growth and is particularly important for the development and security of a country.Therefore,how to promote innovation,especially basic research,in the process of China's modernization is a vital question that needs to be answered.In the innovation process of basic and applied research,it is important to have interaction between researchers,especially face-to-face communications.Reducing communication costs plays an important driving role in both applied and basic research innovation.This study investigates how lower local communication costs promote basic research in China using data from published studies.The extensive infrastructure development of China has not only propelled the country toward becoming a powerhouse in transportation but also significantly contributed to reducing the cost of interactions.With an increasing number of cities launching rail transit to alleviate congestion and reduce commuting times,as of the end of 2021,51 cities across 31 provinces(including autonomous regions,that is,municipalities directly under the Central Government)and the Xinjiang Production and Construction Corps had 269 urban rail transit lines in operation,covering a total length of 8,708kilometers.Over the past two decades,there has been a notable increase in both the operational mileage and passenger volume of China's subways.Compared with applied research,the outcomes of basic research innovation are more open and easily disseminated,thus generating more knowledge spillovers from face-to-face interactions.We consider the construction of urban subways as a quasi-natural experiment and employ a difference-in-differences approach to identify the causal effect of reduced local communication costs on academic exchanges,scientific collaboration,and basic research output
