The article examines how different regions in the European Union are either coming closer together economically (convergence) or moving further apart (divergence). By looking at local data, the researchers found that some regions are getting more similar in terms of wealth, while others are becoming more different. This uneven process of integration suggests that current policies may need to be adjusted to better address these disparities. The study highlights the importance of considering the specific characteristics of each region and its neighbors when designing policies to promote economic growth and reduce inequalities.
