Przewagi konkurencyjne krajów UE - analiza sieci wymian społecznych
The aim of the paper is to introduce social network analysis framework in order to explore relationships among EU countries as a set of exchange relations. Relational data based on 3 dimensions (cultural, social, economic) was an input to stochastic bayesian blockstructures modeling. Three latent classes of symmetrical and asymmetrical relations among countries were found with respected a posteriori probabilities of class membership. The analysis was done with the help of StOCNET software.
