本文以廈門大學嘉庚建築符號的百年流變為研究對象，探討建築如何在動態的符號實踐中參與並塑造「廈大人」這一想像共同體的身份政治。研究突破既往將嘉庚建築視為靜態「民族主義象徵」的論述，引入「身份政治」的動態視角與「符號制度化生命週期」的分析框架，追溯其從陳嘉庚基於「南洋華僑現代性」的在地創造，到被學術總結並編碼為可複製的風格範式，在校區擴張中引發內部爭議，最終在全球化進程中跨境調適的完整歷程。論文指出，嘉庚建築的流變並非單純的形式演進，而是一場持續圍繞文化解釋權、認同邊界與話語權力展開的身份政治過程。建築既是凝聚共同體的關鍵媒介，也是內部差異、代際協商與價值衝突的可見場域。研究揭示，建築符號的神話化具有整體不可逆性，但其具體呈現仍可在實踐中被擾動與再編碼。而符號在跨境移植中呈現的「策略性排序邏輯」，則揭示了全球化背景下文化符號如何被重構為一種服務政治與認同目標的「戰略現代性」，以及建築符號與集體認同之間深刻而動態的互構關係。

This study explores the century-long evolution of Tan Kah Kee architectural symbols at Xiamen University, focusing on their role in shaping the identity politics of the "Xiamen University community" as an imagined community through dynamic symbolic practices. Moving beyond static "nationalist symbol" narratives, it adopts an "identity politics" perspective and "institutionalized symbolic life cycle" framework, tracing the symbols’ trajectory: from Tan’s local creation rooted in "Nanyang overseas Chinese modernity" to academic codification as a replicable style, internal controversies in campus expansion, and cross-border adaptation amid globalization.

The research argues this evolution constitutes ongoing identity politics over cultural interpretation rights, identity boundaries, and discursive power. Architecture serves as both a community cohesion medium and a visible arena for internal differences, intergenerational negotiations, and value conflicts. It reveals irreversible symbolic mythologization—yet mutable manifestations—and that the "strategic ordering logic" of cross-border transplantation reconstructs cultural symbols as "strategic modernity" for political and identity goals under globalization.

Ultimately, the symbols’ evolution reflects the "Xiamen University community’s" ongoing self-definition, negotiation, and reconstruction via architectural discourse, highlighting the dynamic mutually constitutive relationship between architectural symbols and collective identity.
