Spatial Knowledge Spillovers in Europe: A Meta-Analysis
(), Peter Warda
() and Urban Gråsjö
Abstract: In this paper we quantitatively review the empirical
literature on spatial knowl¬edge spillovers in Europe by means of
meta-analysis to determine the extent to which such spillovers have been
empirically documented as well as the spatial reach of these spillovers. In
addition, we will apply meta-regression analysis to analyze the
determinants of observed heterogeneity across and between publications. To
our knowledge this is the first study of its kind. Our results show that if
total local R&D expenditure in a European region increases by 1%, then the
number of patents in that region, on average, increases by about 0.5%.
Spatial knowledge spillovers induce a positive effect on local knowledge
production, however, this effect proves to be small around 0.07%. Spatial
weighting regime seems to matter. If R&D expenditures in other regions are
weighted by distance in kilometers or minutes (instead of a binary
contiguity matrix) then the spillover effect on average will be larger.
Also, public R&D expenditure is found to have a lower impact on local
patent production compared to the private R&D expenditure.
