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.read more

When Do Global Pipelines Enhance the Diffusion of Knowledge in Clusters
TL;DR: A formal model to investigate when global pipelines contribute to an increase in local knowledge, depending on various characteristics of clusters such as size, knowledge endowment, and the ease of transmission of internal knowledge is developed.

The role of collaborative networks in supporting the innovation performances of lagging-behind European regions
TL;DR: In this paper, the capacity of local innovative organizations embedded in lagging-behind European regions to develop internal and external regional inventors' networks by exploring their collaborative patenting processes was measured.

Knowledge flows and the absorptive capacity of regions
TL;DR: The authors assesses the extent to which absorptive capacity determines knowledge flows' impact on regional innovation and finds evidence that inflows of inventors are critical for wealthier regions, while it has more nuanced effects for less developed areas.

Centrality in social networks conceptual clarification
TL;DR: In this article, three distinct intuitive notions of centrality are uncovered and existing measures are refined to embody these conceptions, and the implications of these measures for the experimental study of small groups are examined.

Endogenous Technological Change
TL;DR: In this paper, the authors show that the stock of human capital determines the rate of growth, that too little human capital is devoted to research in equilibrium, that integration into world markets will increase growth rates, and that having a large population is not sufficient to generate growth.
