In the study of comparative politics, we need a theory that is applicable in analyzing of a ‘political change’ or ‘institutional change’. This article attempts to gain a view of such comparative politics theory, focusing on ‘ideational approaches’. Through the review of existing various ideational approaches in political science, this article argues the potential of ideational approaches for analysis of political change.
First, for ideational approaches, it is necessary to highlight not only the existence of ideas per se but also the function of ideas in the political processes. Specifically, we need to focus on the process in which an idea gains wide support from various political actors and thereby coalitions for a political change are built. Second, in case of such coalition building, we need to specify the influences of an idea from the point of view of ‘preference formation’. Third, for more persuasiveness, it is important to take into account the interrelation between ideas and institutions. Finally, this article discusses the possibility of ideational approaches that mediate rationalists, culturalists, and structuralists in comparative politics.
