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...

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...

We investigate the impact of actors' positions within regional innovator networks on their innovative performance. The networks of four selected regions are based on information on patent applicants and inventors. Count data regressions show positive effects on innovation of both the total...

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,...
