Elettori e partiti nell'Europa contemporanea: Est ed Ovest a confronto

The research is focused on the origin and the structure of the European party systems in long-standing democracies and in post-communist countries. Considering the differences between the western frozen party systems and the eastern unfrozen party systems, we propose a framework of analysis based on the theoretical and conceptual linkage between genetic approach and spatial theories of competition, identified in the normative component of a cleavage. At first, we propose some operational criteria to distinguish the dimensions of competition from the dimensions of identification through the use of the manifesto project surveys. Then, through the data of an expert survey and of some recent electoral mass surveys, we empirically test a set of propositions concerning, on the one hand, the congruence between party policy positions and party-voters policy positions and, on the other hand, the level of correlation between parties positions on different issue dimensions and their placement on the left-right axis.
