Stimulating Collaborations: Evidence from a Research Cluster Policy
研究了法国大规模研究集群政策如何影响研究者之间的合作，发现受资助集群成员之间的合作增加高达30%，且非核心主题的研究者受益最大。
Abstract The production of knowledge relies on collaborations between researchers. However, we do not know to what extent policies may stimulate these interactions. In this paper we show how a large-scale public “research cluster” policy in France, which funds local communities of researchers working on a common theme, affects the organization of research. Relying on an identification strategy based on grades awarded by reviewers, we show that members of financed clusters increase their collaborations with other cluster members by up to 30%. Paradoxically, researchers not at the core of the cluster topic benefit the most from the policy.
