Despite the growing number of studies, still little is known about how network structures and proximity relations between linked actors evolve over time. Arguments are put forward for the existence of co-evolution dynamics between different types of proximity configurations within networks. An empirical investigation tests these arguments using information on the development of 280 networks. Amongst others, it is shown that institutional and cognitive proximity configurations coevolve in the short as well as in the long-run. While institutional and social proximity configurations are only related in the long run. Moreover, temporal auto-correlation dynamics characterizes the development of cognitive proximity configurations.

Economic geography has developed a stronghold analysing how geography impacts innovation. Yet, despite increased interest in networks, a critical assessment of the role of geography in the evolution of networks is still lacking. This paper juxtaposes geographical proximity with the network of prior ties as alternative mechanisms for tie formation. Analysing the evolution of inventor networks in German biotechnology, the paper theoretically argues and empirically demonstrates that – as the technological regime of an industry changes over time – inventors increasingly rely on network resources by forming links to partners of partners, whilst the direct impact of geographical proximity on tie formation decreases.
