Polarized States: Political Polarization in the United States in the 21st Century/极化国家:21世纪以来的美国政治极化

This book takes contemporary American political polarization as its starting point, systematically analyzing the interaction mechanism between political polarization and the operation of American democratic politics from two dimensions: historical evolution and institutional structure. Based on historical analysis, the book constructs a theoretical explanatory framework centered on party politics, striving to comprehensively reveal the deep structure of the operation of American parties and the logic of political operation in the 21st century. Unlike existing research that often focuses on the perspective of social attitude differentiation or public opinion fragmentation, this book emphasizes the inherent tension between the party system, political games, and the constitutional system, attempting to explain the structural dilemmas faced by American democracy from an institutional perspective.

本书以当代美国政治极化现象为切入点, 从历史演变与制度结构两个维度出发, 系统分析政治极化与美国民主政治运行之间的互动机制。在历史分析的基础上, 本书构建了以政党政治为核心的理论解释框架, 力图全面揭示21世纪美国政党运作及政治运行逻辑的深层结构。不同于现有研究多聚焦于社会态度分化或舆论撕裂的视角, 本书强调政党制度、政治博弈与宪政体制之间的内在张力, 尝试从制度层面解释美国民主所面临的结构性困境。
