Do birds of a feather flock together? Proximities and inter-clusters network

The present contribution develops on the analysis of clusters in terms of proximities by exploring the issue of distant inter-cluster collaborations. We mobilize different forms of proximity (geographic, cognitive, social) discussed in the literature in order to identify their respective influence on intercluster collaboration by taking the example of French Pôles de Compétitivité. Our results echo previous results applied to intra-cluster collaborations since inter-cluster collaboration mostly relies on a form of social capital due to the key roles played by relational and cognitive proximity. Finally, our results exhibit a negative influence of geographic distance on collaboration.
