Abstract

This paper investigates the determinants of co-inventor tie formation using micro-data on genomic patents from 1990 to 2006 in France. In a single analysis, we consider the relational and proximity perspectives that are usually treated separately. In order to do so, we analyse various forms of proximity as alternative driving forces behind network ties that occur within existing components (i.e. closure ties) as well as those between two distinct components (i.e. bridging ties). In doing so, we contrast network and proximity determinants of network formation and we investigate to what extent social networks allow economic actors to cross over geographical, technological and organizational boundaries.
