Proximity, Networks and Knowledge Production in Europe. (Forthcoming in Technological Forecasting and Social Change)

This paper aims at assessing the role of various dimension of proximity on the innovative capacity of a region within the context of a knowledge production function where we consider as main internal inputs R&D expenditures and human capital. We want to assess if, and how much, the creation of new ideas in a certain region is the result of flows of information and knowledge coming from proximate regions. In particular, we examine in details the concept of proximity combining the usual geographical dimension with the institutional, the technological, the social and the organizational proximity. The analysis is implemented for an ample dataset referring to 287 regions in 29 countries (EU27 plus Norway, Switzerland) for the last decade. Results show that human capital and R&D are clearly essential for innovative activity but with an impact which is much higher for the former factor. As for the proximity and network effects, we find that geography is important but less than technological and cognitive proximity. Social and organizational networks are also relevant but their role is more modest. Finally, most of these proximities prove to have a complementary role in shaping innovative activity across regions in Europe. Jel classification: C31, O31, O18, O52, R12
