The paper targets the relationship between growth of cooperation and later growth of innovation at the regional level. Patent data for German regions and eleven subsequent years is used to identify collaborative activity as well as the innovative output in each region. The results confirm to...

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...

We investigate the lead-lag relationship between growth of patent applications, growth of R&D, and growth of total sectoral employment for 270 German labour market regions over the period 1999-2005. Our unique panel dataset includes information on four two-digit industries, namely Chemistry,...

Collaboration is an important factor for regional economic growth. Still, the literature lacks explanations why some regions collaborate more or less than expected. The present paper proposes regional culture as influencing factor, being region-specific and connected to interactive activities....

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...

Popular theories claim that innovation activities should be located in large cities because of more favorable environmental conditions that are absent in smaller cities or remote and rural areas. Germany provides a clear counterexample to such theories. We argue that a main force behind the...

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...
