Using existing research, this study emphasises on some issues that were ignored or not addressed enough the literature on institutional change which is integrating the new institutional theory and social movement theory. These issues are related to the roles of state as an actor and social movements, using noninstitutional channels in the process of institutional change, and the impacts of differences in the structure of political opportunity in a different context. It is claimed that structural conditions in different countries and these conditions‟ impact on the channels, the movements use, and their success should be addressed in the institutional change studies
