Title : Small Worlds in Networks of Inventors and the Role of Science: An Analysis of France
Author(s) : Francesco Lissoni, Patrick Llerena, Bulat Sanditov
Abstract : Using data on patent applications at European Patent Office, we examine the structural properties of networks of inventors in France in different technologies, and how they depend from the inventive activity of scientists from universities and public research organizations (PROs). We revisit earlier findings on small world properties of social networks of inventors, and propose more rigorous tests of such hypothesis. We find that academic and PRO inventors contribute significantly to patenting in science‐based fields. Such contribution is decisive for the emergence of small world properties.
Key-words : networks, inventors, academic patenting, small world.
