Abstract

A rich literature has emerged that analyzes the emergence of inter-organizational networks. However, little is still known about how and why the (global) structures of such networks differ between technologies. Based on a rich database covering subsidized R&D cooperation in Germany, we compare cooperation networks of 10 distinct technologies. A particular focus is hereby on the existence of systematic differences between networks that are dominated by firms and those that primarily connect public research organizations. Among others, we find that the first tend to be larger and less dense with big firms being the most central organizations. In comparison, networks dominated by public actors are stronger centralized and involve more isolates.
