[en] This paper aims at introducing a novel measure of regional centrality in the context of R&D
networks. 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.
