Chapter 2 Integration, Growth and Core-Periphery Pattern in EU’s Economy: Theoretical Framework and Empirical Evidences

The unequal distribution of economic activities, transposed in economic, social and territorial disparities is the general characteristic of the European economy. Gaps increased in the context of European Union (EU) enlargement towards Eastern and Central Europe and of the economic crisis, thus bringing new differentiations among member states’ economies. The main aim of the chapter is to emphasise the centre-periphery differentiations in the European economy, by using a composite index of peripherality, in order to better understand the determinants of growth and convergence in Central and Eastern European countries and to reach normative conclusions for increasing Cohesion Policy (CP) effectiveness. The first part of the chapter provides a short overview of the main theories and models of the peripherality analysis and the relationships between the centre and the periphery, in order to find out how this analysis relates to the research in the field. The second part provides a comparative analysis of the evolution of European economies during 2003–2014, in order to find out whether the EU enlargement process stabilised the EU core-periphery pattern or, on the contrary, the process of core-periphery structural convergence occurred. The third part includes the suggested model of analysis (methodology, data, and main results) from a multidisciplinary perspective, underlining the centre-periphery differentiations on the two axes, North–South and West–East. The results have been interpreted in conclusions, with a focus on their relevance for the European CP challenges.
