【摘要】This paper investigates the embeddedness of European regions in different types of inter-regional knowledge networks; namely project-based R&D collaborations within the European framework programmes (FPs); co-patent networks and co-publication networks. Embeddedness refers to the network positioning of regions captured in terms of social network analytic (SNA) centrality measures. The objective is to estimate how region-internal and region-external factors influence network embeddedness in the distinct network types; in order to identify differences in their driving factors at the regional level. In our modelling approach; we apply advanced spatial econometric techniques by means of a mixed effects panel version of the spatial Durbin model (SDM) and introduce a set of variables accounting for a capacity specific; a relational as well as a spatial dimension in regional knowledge production activities. The results reveal conspicuous differences between the knowledge networks. Internal capacity- and technology-related aspects but also spatial spillover impacts from surrounding regions prove to be particularly important for centrality in the co-patent network. We also find significant-region-internal and region-external-impacts of general economic conditions on a region's centrality in the FP network. However; we cannot observe substantial spillover effects of region-external factors on centrality in the co-publication network. Thus; the distinctive knowledge creation foci in each network seem to find expression in the network structure as well as its regional determinants.
