研究成果概要
This research project addresses the effects of European integration on the actual and perceived ideological positions of parties and links the extent of mainstream parties' ideological convergence to the success and failure of challenger parties. Using manifesto data from CMP and survey data from CSES, I conducted a series of empirical analyses to test these relationships. I obtained important empirical findings which have implications for the literature on European integration and party competition. My results suggest that more European integration reduces the ideological distance among mainstream parties and is associated with more widespread perceptions of mainstream party convergence among voters. Analyses of the electoral performance of challenger parties point to the effects of both actual and perceived ideological convergence: challenger parties receive more votes when the moderate mainstream parties converge. Likewise, voters who see the mainstream parties as ideologically similar are more likely to have voted for a challenger party.
