It quantifies the effect of the regions´ own technological inputs, and the externalities associated with them, on regional patenting. The analysis is based on the estimation of a knowledge production function. A region’s own R&D activities and human capital are observed to have a positive significant effect on innovation output, measured by the number of patents. R&D spillovers weighted by the distance and the volume of trade flows between regions cause positive effects on a region’s patents. However, distance matters more than the intensity of trade flows and the R&D spillover effects between regions are bounded: spillovers from closer regions perform better than spillovers from distant regions. On the opposite side, human capital spillovers do not cause any effect outside the region itself.}, }
