We first demonstrate some substantial problems of SNA-based centrality measures to cope with regional R&D networks in a meaningful way. Then, we introduce a new measurement approach of regional network centrality based on the concept of inter-regional bridging paths (indirect connections at the regional level). We show that the formal definition of our regional bridging centrality measure can be expressed in terms of three simple components: the participation intensity of a region in inter-regional R&D collaborations, the relative outward orientation in terms of all established links and the diversification of R&D collaborations among partner regions. We illustrate the measure and its behaviour with respect to other conventional centrality measures by using the European co-patent network at the NUTS 2 level. | | Keyword(s): | network centrality of regions, inter-regional R&D networks, inter-regional bridges, aggregated networks, co-patent network | | Auteur(s) : | Laurent BERGÉ, Iris WANZENBOCK, Thomas SCHERNGELL | | JEL Class.: | D85, L14, O31 | Télécharger le cahier Retour à la liste des Cahier du GRETHA (2015) |
