Learning from the best: how regional knowledge stimulates circular economy transition at company level

This paper investigates whether, and what kind of, regional knowledge has a stimulating effect on circular economy (CE) innovation by companies. We thus add to the literature on regional knowledge spillovers, which has rarely focussed explicitly on the CE. For the empirical study, we create econometric regressions based on a representative dataset with extensive information on the CE activities of about 1400 Swiss firms. The results confirm that regional knowledge is important for the implementation of CE innovations. However, geographical distance and the quality of the knowledge must be taken into account, that is, companies primarily learn from the best.
