The last decades saw a pronounced shift in innovation policy in Germany and many other countries towards increased funding of cooperative R&D. Over the last years, competitions between regional initiatives pushed this trend even further by adding a regional perspective, by increasing the scope...

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...

We attempt to extend the static analysis of innovator networks by providing case study based insights into the dynamic, developmental or evolutionary pattern of such networks. In the theoretical part, we develop some building blocs that are considered central to a theory of network evolution....

The flow of knowledge through interaction between innovative actors is central to the systemic view of innovation. We review the literature on interaction and innovator networks with a focus on regional aspects. To illustrate the relevance of these relations, we apply social network analysis...

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...

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...

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...

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...

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...
