Innovator networks and regional knowledge base

This paper concerns the regional innovation system approach. It deals with the characteristics of three regional systems, Northern Hesse, Alpes-Maritime and Jena, and focusses on each regional network of innovators. In this context the importance of the size and homogeneity of a regional pool of knowledge spillovers for those networks is analyzed. We ï¬nd evidence that an increasing regional knowledge base in combination with an increas- ing homogeneity of this knowledge base enhances the knowledge flows and the incentives for actors to interact with each other.
