Innovation, spillovers and university-industry collaboration: an extended knowledge production function approach

This article analyses the effect of knowledge spillovers from academic research on regional innovation. Spillovers are localized to the extent that the underlying mechanisms are geographically bounded. However, university-industry collaboration-as one of the carriers of knowledge spillovers-is not limited to the regional scale. Consequently, we expect spillovers to take place over longer distances. The effect of university-industry collaboration networks on knowledge spillovers are modelled using an extended knowledge production function framework applied to regions in the Netherlands. We find that the impact of academic research on regional innovation is not only mediated by geographical proximity but also by networks stemming from university-industry collaboration.
