Club convergence in innovation activity across European regions

The goal of this paper is to analyse the innovation activity convergence process across European regions from 2002 to 2012. A novel methodology that allows either detection of overall convergence or endogenous identification of groups of regions was applied. The results support the club convergence hypothesis for explaining the convergence process of Europe's regions during the period analysed and seven innovation convergence clubs were identified. In addition, the research results indicate that initial regional R&D expenditure is the most relevant factor driving the formation of the convergence clubs after controlling for the effects of regional structural characteristics.
