The role of geographical proximity in fostering connections and knowledge flows between innovative actors ranks among the most controversial themes in the research of innovation systems, regional networks and new economic geography. While there is ample empirical evidence on the constituent...

Economists pay more and more attention to knowledge networks and drivers of their development. Consequently, a rich literature emerged analyzing factors explaining the emergence of intra-organizational links. Despite substantial work focusing on the dyad level, only little is known about how and...

We analyze the evolution of the international collaboration network in photovoltaic research. Using data on scientific publications for the period 1980-2015, we apply social network analysis to trace the evolution of the global network of countries and national research networks of...

The positive effect of public research on industrial innovations is beyond controversy: public research institutions produce knowledge that is subsequently transferred into product and process innovations by private businesses. Besides this rather passive role in commercializing inventions,...

Cluster studies have shown that innovation can be understood as the result of an inter- organizational process, where a division of labor with regard to exploration and exploitation exists among the actors inside the cluster. A cluster is ambidextrous if it manages to balance innovative...

The article serves as an introduction to the empirical analysis of innovation or knowledge networks based on patent data with a particular focus on regional networks. I provide a review of the literature of innovation networks and how it connects to systemic approaches within the field of...

We study the effects of a German national cluster policy on the structure of collaboration networks. The empirical analysis is based on original data that was collected in fall 2011 and late summer 2013 with cluster actors (firms and public research organizations) who received government...

Technological change and gains in efficiency of renewable power generation technologies are to a large extent driven by governmental support. Various policies that can broadly be categorized as technology push, demand pull or systemic constitute a policy mix for renewable energies. Our goal is...
