Getting into networks and clusters: evidence from the Midi-Pyrenean global navigation satellite systems (GNSS) collaboration network, Regional Studies. This paper analyses clusters from collaborative knowledge relations embedded in wider networks in a particular technological field. Focusing on the interface of clusters and networks contributes to a better understanding of collaboration, within and across places and cognitive domains. An empirical analysis of the Midi-Pyrenean global navigation satellite systems (GNSS) cluster is proposed based on a relational database constructed from collaborative research and development projects funded at the European, national, and regional levels. Using Social Network Analysis tools, the results are discussed according to (1) the structural, technological, and geographical dimensions of knowledge flows; (2) the influence of particular organizations in the structure; and (3) the heterogeneity and complementarities of their position and role. The paper concludes by showing that the findings provide new opportunities for cluster theories.
