الأنظمة السياسية وأثرها في أداء المؤسسات الدستورية: نماذج مختارة (كولومبيا– تايوان– بولندا)

This research aims to analyze the impact of presidential and mixed systems on the performance of constitutional institutions, with a focus on the executive and legislative branches, through a study of selected models: Colombia, Taiwan, and Poland. The research starts from the question of the extent to which the nature of the political system affects institutional performance efficiency and the mechanisms of power distribution and interaction between constitutional authorities, especially in the context of political and social crises.

The study adopted a descriptive analytical approach and a case study approach, allowing for an in-depth understanding of each political experience in its constitutional, historical, and political context, away from strict comparisons. The research concluded that the performance of constitutional institutions is not only determined by the nature of the political system adopted, but is also influenced by the political context and level of stability, the nature of relations between authorities, and the ability of institutions to manage crises.
