This article assesses the relative importance of partisanship in explaining level of citizens' political engagement within a multivariate framework. In particular, we examine if the relative worth of partisan attachment in explaining civic engagement differs systematically between East Asian emerging democracies and established democracies. We find that partisanship in East Asia exerts just as much influence on citizens' engagement in politics as in established democracies. The global trend in which interest associations and social movements are becoming vigorous competitors to parties for the opportunity to represent and mobilize citizens in democratic process has also spread to East Asia.
