The evaluation of European structural funds on economic convergence with the application of spatial filtering technique

This paper aims to identify empirical regularities relating innovation persistence across regions and different types of innovation. The analysis is based upon three waves of the Community Innovation Survey data that cover the period 1998-2009. The main findings are: (i) across all regions Portuguese firms are more likely to introduce in the market process innovations than product innovations; (ii) the degree of correlation between geographical location and innovative output varies with the innovation type; (iii) both innovative activities and persistence are asymmetrically distributed across regions.
