This article, through examining the actual effect of political culture (as a variable) in the two nations' democratic movement and the relationship between the political culture and the political developing path of these two nations, is aimed at demonstrating that it is important to fully consider the complexity of political culture background and the positive and negative impact therefrom in order for the model of transition more fit for the requirement of a nation's society and the demand of contemporary development, especially when designing the model of transition to democracy.
