Large Firms and Knowledge Flows in the Dutch R&D System: A Case Study of Philips Electronics

This paper uses data on patent-to-patent citations and patent-to-science-literature citations to study the spillover network of companies and research institutes around Philips Electronics. The theoretical section of the paper surveys the literature on innovation regimes and regional systems of innovation, and uses this to derive a number of testable hypotheses on the Philips network. The main findings of the paper are that the importance of local firms in the technology network around Philips is small, but the impact of local (semi-)public institutes is larger. Also, it is found that large firms generate a large part of the scientific literature that is referred to in Philips patents.
