Effects of cluster policies on regional inventor networks: evidence from France
研究法国集群政策对本地发明人网络结构的影响，发现考虑空间依赖和区域特定趋势才能正确推断政策效果，但整体上政策并未显著增强网络的凝聚力、效率和韧性。
Focusing on the French cluster policy, this study aims at evaluating how cluster policies influence the structure of local inventor networks. Based on a panel data of four periods and 94 NUTS-3 French regions, we implement various model specifications to make explicit processes that may drive the impact of the policy. The results suggest that spatial interdependences and region-specific trends should be considered to make correct causal inference about such place-based policies. Overall, the results do not provide clear evidence supporting that the French cluster policy has strengthened the cohesion, efficiency and resilience of local inventor networks.
