"Core-Periphery" in the European Union – An Economic Perspective
The heterogeneity of economic performances in the EU member states is one of the main reasons for the existence of a “core-periphery” relationship. The goal of this research is to examine various economic indicators to reveal possible divisions between the EU members. This issue emphasized the contribution of rich “core” countries to the imbalances in poorer “peripheral” EU members. By applying cluster methodology and considering the most recent data, two groups of countries were identified, the first comprising 11 countries that form the “centre” or the “core”, and the rest of the EU forming the “periphery”. Considering differences between these countries is necessary and justified for discussions about the future development of the EU that will involve differences between member states.
