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 number of relations and of access to a larger knowledge base. However, when looking at innovators that are characterised by multiple internal and external contacts, our results suggest that these gatekeepers are not able to reap all the benefits associated with their brokering position. This implies that gatekeepers provide some sort of public good to the innovation system.
