Abstract: | The recent resurgence of growth studies has clearly established that technological progress and knowledge accumulation are
among the most important factors in determining the performance of regional and national economic systems. In this paper we
propose new evidence on knowledge flows across European regions based on patenting at the European Patent Office. We examine
in- and out-flows of patent citations as a proxy of knowledge connections, while looking also at their dynamics through time.
The econometric analysis is based on a model where the exchange of knowledge across regions is mainly affected by geographical
distance together with a set of spatial variables. The main result is that knowledge flows decrease as the geographical distance
between the origin and the destination region increase. Furthermore, knowledge flows tend to be higher among contiguous regions
and areas within the same country. These results prove to be robust with respect to the inclusion of other characteristics
of the origin and destination regions (production structure, economic conditions and technological efforts) as well as different
estimation methods. |
