Abstract

This paper has two main objectives. First, it estimates the impact of related and unrelated variety of European regions’ knowledge structure on their patenting activity. Second, it looks at the role of technological relatedness and extra-local knowledge acquisitions for local innovative activity. Specifically, it assesses how external technological relatedness affects regional innovation performance. Results confirm the strong relevance of related variety for regional innovation; whereas the impact of unrelated variety seems relevant only for the generation of breakthrough innovations. The study also shows that external knowledge flows have a higher impact, the higher the similarity between these flows and the extant local knowledge base.
