Heterogeneity of Research and Development Expenditure: A Convergence Analysis for the Spanish Regions

In the present study, we investigate the convergence of research and development (R&D) expenditure, a relevant factor in competitiveness, across Spanish regions through a club convergence analysis for the period 2000 to 2017. The results show large regional disparities in R&D expenditure in Spain. We have identified four clusters, plus a divergent region: the Basque Country. The results are similar for the two perspectives considered: percentage of GDP and per capita. We discuss these results taking into account the effects of the Great Recession and compare the outcomes with those for a club convergence of regional GDP per capita. Finally, we carry out an ordered logit model to analyse the factors behind the clusters, with human capital and economic openness being significant.
