University as catalyst of public R&D expenditures? An empirical assessment on EU NUTS 3 regions

Abstract

This study examines whether universities shape the regional innovation effects of public R&D expenditure and whether this role varies across regional development trajectories. We analyse a panel of 1166 EU NUTS 3 regions over the period 2007-2020, combining data on European public R&D funding, patenting performance, university presence and regional development traps. Toa ddress the endogeneity of public R&D expenditure, we employ a control function aproach. The results show that public r&D expendirue positively affects patenting performance in both university and non-university, but the difference between them is not statistically significant. University presence therefore does not sistematically amplify the returns to public R&D. However, its moderating role becomes more pronounced in regions exposed to development trap risk and in regions experiencing persistent stagnation, while evidence is weaker for trap intensity. These fundings suggest that universities act as contingent rather than unviersal catalyst of public R&D. Their contribution appears particularly relevant in vulnerable and persistently stagnant regional trajectories, but less able to offset sever structural constraints. The study contributes to debates on the geography of public R&D and regional development traps by showing that the effectiveness of research funding depends not only on institutional presence, bu also on the development rajectory in which that institutional capacity is embedded.
