偏见于人与生俱来亦无处不在，是跨文化研究的经典议题。但传统的心理学、社会学等研究范式取径单一，缺乏统合性的理论视角和模型指标。整合威胁理论沿袭了社会认同论、现实群体冲突论与象征种族主义对偏见的系统性探索，将对威胁的关注提升至偏见研究的中心地位，搭建起从多元前因到偏见后果的流程链路。研究以此出发，挖掘整合威胁研究的学术脉络、廓清理论体系，尝试在文化差异、群际关系、多元文明与边缘群体等维度将该理论应用于跨文化传播中来，以解构、重构核心议题，从而为穿越地方性文化场景探索文化偏见之源、理解多文明政治与跨文化交往的现实逻辑提供可扩展的方向。

The existence of prejudice in human beings is innate and ubiquitous, making it a classic topic of cross-cultural research. However, the conventional research paradigms in fields like psychology and sociology have tended to take a narrow approach, lacking a unifying theoretical perspective and comprehensive indicator models. Integrated threat theory builds upon the systematic exploration of prejudice by social identity theory, realistic group conflict theory and symbolic racism, elevates the focus on threat to the central position of prejudice research, and sets up a process path from multiple antecedents to the consequences of prejudice. Starting from this, the research delves into the academic context of integrated threat theory and elucidates its theoretical framework, trying to apply this theory to intercultural communication in the dimensions of cultural differences, intergroup relations, diversified civilization and marginal groups, so as to deconstruct and reconstruct the core issues. Thus, it provides an expandable direction for exploring the origins of cultural prejudice in navigating local cultural scenes and comprehending the reality logic of multicultural politics and cross-cultural interactions.
