The concentration and dispersion of innovative activities in space has been largely explained and evidenced by the nature of knowledge and the geographical extent of knowledge spillovers. One of the empirical challenges is to go beyond by understanding how the geography of innovation is shaped...

Vicente J. and Suire R. (2007) Informational cascades versus network externalities in locational choice: evidence of 'ICT clusters' formation and stability. Regional Studies 41, 1-12. The paper provides new insights into the mechanisms of 'information and communication technology (ICT) clusters'...

This paper investigates the driving forces behind the life cycles and resilience of technological clusters. It concentrates in particular on the combination of critical parameters that allows clusters to succeed in disconnecting their cycle from the cycle of the technologies they produce, in...

French Abstract: A la suite d'une abondante littérature sur le rôle important du développement des clusters pour l'innovation et la croissance dans les économies fondées sur la connaissance, les politiques de cluster ont été récemment et de façon croissante remises en cause par les...

This paper contributes to the empirical identification of geographical and structural properties of innovative networks, focusing on the particular case of Global Navigation Satellite Systems (GNSS) at the European level. We show that knowledge bases of organizations and knowledge phases of the...

This paper contributes to the empirical identification of clusters based on network analysis. We start with the detection of a composite knowledge process rather than a territorial one stricto sensu. Networks and clusters correspond to the complex aggregation process of bi or n-lateral relations...
