Assessing the collaboration and network additionality of innovation policies: a counterfactual approach to the French cluster policy
利用外部网络数据构建反事实方法，评估法国集群政策是否促进企业合作、本地联系及网络附加性，发现政策难以提升企业在知识网络中的中心性。
Abstract Whereas most collaboration-based innovation policies aim at fostering efficient ecosystems of innovation, evaluations of the behavioral impact of such policies remain few and far between. Relying on external-to-the-policy network data to build a counterfactual approach, this article addresses three main evaluation issues: do cluster policies make firms more collaborative? Do they encourage local ties? Do they induce network additionality? Focusing on French data, our results suggest that cluster policies may have difficulty in increasing the centrality of agents within knowledge networks.
