With the consideration of Dalton's ＂good citizens＂ theory, this study compares people's normative beliefs about citizenship cross-nationally, and investigates individuals' acquisition of citizenship norms by the case of Taiwan. By analyzing two waves of survey data of ISSP, we confirm that beliefs about citizenship norms can be divided into three aspects: civic responsibility, autonomous participation, and community duty. Also, respondents' citizenship norms in old democracies are different from those in new democracies, but patterns in the two country groups change in the same direction. Taking individuals' age into account, both our cross-national comparison and empirical analysis on Taiwanese respondents support the explanation of individuals' political learning. This study not only extends Dalton's research to a comparative context, but also implies that there is still much room for improvement in democratic civic education and the deepening of citizenship norms of Taiwan.
