Various forms of interaction during the process of research and innovation constitute a global network of knowledge generation and diffusion. Countries and their research organizations and individual scientists need to be embedded in this network to participate in global knowledge ows and to...

The transfer of knowledge and technology from academia to industry is usually understood as a process. While previous research focuses on phenomena along the process and its outcomes, the starting point of the process - the initiation of a transfer activity - remains unstudied. We provide first...

We analyze the development of the German knowledge base measured by co-classifications of patents by German inventors and relate this technological development to changes in the structure of the underlying inventor networks. Our central hypothesis states that technologies which become more...

Cluster policies are often intended and designed to promote interaction in R&D among colocated organisations, as local knowledge interactions are perceived to be underdeveloped. In contrast to the popularity of the policy measure little is known about its impact on knowledge networks, because...

Cluster policies aim at improving collaboration between co-located actors to address systemic failures. As yet, cluster policy evaluations are mainly concerned with effects on firm performance. Some recent studies move to the system level by assessing how the structure of actor-based knowledge...

The concept of Bridging Technologies (BTs) refers to technologies which are important for the regional knowledge base by connecting different fields and thereby enabling technological development. We provide analytical tools to identify BTs and study their evolution over time. We apply these...

Does exporting intermediate goods induce learning from importers? In this paper, we examine to what extent learning from German industries can be explained by knowledge spillovers, channeled through the export of intermediate goods. Our study is based on a sample of 27 German trade partners in...

We analyze the role of universities or, more generally higher education institutions (HEIs), in terms of their regional and international embeddedness for regional knowledge base renewal. We assume that the introduction of radical patents in the sense of novel technological combinations...
