The Patterns of Party Polarization in East Asia

Abstract

The alignment of parties within a party system shapes the nature of electoral competition, the process of representation, and potentially the legitimacy of the system. This article describes the distribution of parties and the levels of party polarization in the party systems of East Asian democracies. We examine the public's perceptions of party positions on a left-right scale to map the pattern of party competition. The evidence is based on two waves of surveys from the Comparative Study of Electoral Systems. We describe considerable variation in the polarization of Asian party systems, which has direct implications for the clarity of party choice and the behavior of voters. We conclude with a discussion of the implications of our findings.
