- We explore the link between invention and innovation on the one hand and the level of economic activity and economic growth in Sweden by using patents granted and the quality of patens as our indicators of invention and innovation respectively. Our results indicate that both types of measures are able to explain the level and the changing levelof economic activity equally well. However, an important difference is that the economic activity is affected differently by the two measures. We find that inventions have the strongest marginal effect in regions where economic activity is the highest. Instead, innovations have similar marginal effects across regions with different economic activity. Our interpretation is that quality-adjusted patents sort out "bad" from "good" patents in a manner which reflect economic importance.

Konferensbidrag (refereegranskat)abstract
- This paper examines the effects of regional R&D on patenting for Sweden within an accessibility framework. We use two measures of patenting: number of patents granted per capita and a composite of quality-adjusted patents which we regard as an innovation indicator, respectively. Three conclusions emerge. First, we find that the specification where innovations per capita is used as a dependent variable performs much better than with granted patents per capita for capturing relationships with regional R&D. In fact, quantile regressions over the distribution of different patenting and innovation levels per capita show that R&D efforts within regions affect innovations per capita positively, except for the regions with the lowest levels of R&D. The effetcs on granted patents per capita are less robust and depend inconsistently on the level of R&D. Secondly, accessibility to inter-regional R&D do not affect innovation significantly in our results, which suggests that effects are locally bounded. This implies that studies of the R&D-innovation relationship are plagued by misspecification, since studies tend to show that R&D-effects diffuse to other regions. This is also the case in our study: the inter-regional effects are an important factor for granted patents. Third, the share of university R&D of all regional R&D has no effect on patenting, which suggests that the two types of R&D are substitutes. In view of these results the redommendation must be to use quality-adjusted patents for regional innovation studies rather than patent grants.

Tidskriftsartikel (refereegranskat)abstract
- We study the structure of the interregional inventor networks in Sweden by examining the residence of inventors and coinventors involved in Swedish patent applications to the European Patent Office. Several factors are found to influence the spatial affinity of regions. We find that spatial affinity extends beyond the region if it has less own R&D-related resources (business R&D, university R&D and patenting); if it is close to the other region and if it is relatively small. The resources of that other region plays a positive role if, in analogue fashion, that region has more R&D-related resources.
