摘要

本文研究了大学空间扩张对地方创新活动的影响，并以中国新校区建设为研究对象。通过将新园区建设视为准实验，我们在县企业和环企业层面构建了一个独特的地理编码数据集，并采用差分法进行因果推理。相关结果证实了新校区的建立对地方创新具有成长效应。这种正向影响是新校区通过协同创新和专利引用产生的知识外溢的结果，并随着地理距离的增加而衰减。这些发现表明，新校区的建立创造了一个新兴的创新集群，并具有广泛的政策意义。

More than a new campus: University's spatial expansion, emerging knowledge cluster, and innovation growth

This paper examines the impact of university spatial expansion on local innovation activities, focusing on the construction of new campuses in China. By treating new campus establishment as a quasi-experiment, we construct a unique geocoded dataset at both county-firm and ring-firm levels, and employ the difference-in-difference approach for causal inference. The relevant results confirm that the establishment of new campuses has a growth effect on local innovation. This positive impact is the result of knowledge spillover from the new campus through collaborative innovation and patent citation, and it decays with geographic distance. These findings suggest that the establishment of new campuses creates an emerging innovation cluster and have extensive policy implications.

期刊介绍： The China Economic Review publishes original works of scholarship which add to the knowledge of the economy of China and to economies as a discipline. We seek, in particular, papers dealing with policy, performance and institutional change. Empirical papers normally use a formal model, a data set, and standard statistical techniques. Submissions are subjected to double-blind peer review.
