Abstract
The question of whether there is increasing social integration among EU citizens in Europe as a spill‑over effect of the ongoing process of system integration, as expected by utilitarian perspectives on integration, has been discussed in many contributions so far. In particular, the question of how the economic strength and development of macro‑units affects European social integration has gained new momentum after the 2004 enlargement, when economically weaker ECE countries became part of the EU. In this contribution, I focus on the impact of regional economic strength and development on European social integration. I analyse the relationship between the economic situation and development of NUTS-1 regions and individual European identity using Eurobarometer data for the years 2004, 2010 and 2015. Using descriptive and multivariate quantitative approaches, I show that regional economic strength is weakly correlated with European identity, although not significant in multivariate models. However, citizens who believe that the EU is an economic advantage are more likely to identify as Europeans and are more prevalent in regions with higher economic growth. I conclude that convincing citizens of the economic benefits of EU membership could result in increased European social integration in the long run.
