Is Regional Innovative Activity Path-dependent? An Empirical Analysis for Germany
Eckhardt Bode
Abstract: Based on a standard idea-based model of endogenous growth
we test the hypothesis that regional innovative activity is path-dependent,
and investigate the geographical scope of knowledge spillovers. Using data
for West-German regions, two alternative indicators of the stock of
knowledge are specified. One is based on patent applications, the other on
numbers of researchers. With patents as indicator the path-dependence
hypothesis is rejected, and knowledge spillovers from neighboring regions
appear to be irrelevant. With numbers of researchers as indicator, by
contrast, there is evidence for both path-dependence, and the relevance of
interregional knowledge spillovers. Several extensions and refinements are
discussed which may help resolving these apparent contradictions.
