当下，全球范围内的文化离散现象产生了不得忽视的文化身份问题，处于双重甚至多重文化空间之中的现代离散群体正在遭遇文化身份的“认同危机”。作为文化类节目的标杆，登陆全球社交媒体平台的文博类节目《国家宝藏》引起了海内外观众的追捧，为我国跨文化传播研究提供了代表性的媒介样本。本研究融合符号学、叙事学、修辞学等相关理论范式，引入文化身份认同理论、修辞理论及话语理论对YouTube平台上的《国家宝藏》及评论展开分析，为揭示情感如何建构文化身份认同，提供理论建设与媒介实践上的参考价值。

本研究分为五章，分别为跨文化传播中文化身份认同建构的情感逻辑，综艺节目《国家宝藏》的情感符码：符号、修辞与意义，YouTube平台《国家宝藏》的受众互动与情感效果，跨文化传播中综艺节目受众文化身份认同建构的情感话语，以及跨文化传播中综艺节目受众文化身份认同建构的情感问题与策略。

第一章梳理跨文化传播中文化身份认同建构的情感逻辑，系统阐释跨文化传播中文化身份认同的理论脉络和现实语境，从符号表征和认同建构两个维度溯源跨文化传播中文化身份认同的情感基础，并从媒介仪式、媒介平台、媒介语言三个方面分析媒介驱动下文化身份认同的情感交往。

第二章基于《国家宝藏》共三季合计30期节目，从情感符码的核心符号、文本修辞、意义阐释三个层面展开文本分析。其中，核心符号包含场景、人物、道具以及听觉符号四种类型。以伯克的“认同”修辞观为理论架构，探究节目通过同情同一修辞在故事语境中实现情感共鸣，通过对立同一修辞在战争隐喻下达成情感联盟，通过无意识同一修辞在关系重塑中完成情感映射。在情感符码的编码下，节目得以实现在意境创构中传承文化记忆，在原型唤醒中激活共同情感，在象征积累中重塑文化身份的意义阐释。

第三章探究YouTube平台《国家宝藏》的受众互动与情感效果，首先统计受众与节目互动的量化数据以分析节目互动概况，并抓取5010条有效评论文本，其次利用Jieba分词工具统计受众评论高频词，再通过SnowNLP情感分析工具分析受众评论情感倾向分布以及主要积极/消极情感词，最后借助Gephi绘制高频词及特定情感词的共现网络图，以进一步明确受众的情感体验。研究发现，以文物为载体的文化叙事，能够吸引受众对中华文化的正向关注，鼓励集体积极情感的公开表达，在个体情感述说的过程中，文化身份认同完成了从节目文本语境到社会文化语境的再造。

第四章以费尔克劳话语分析的三维模式，对YouTube平台《国家宝藏》的评论文本展开话语分析。研究发现，节目受众在文化身份认同的语词表达上集中书写了族群身份、离散身份和传承身份三种类型，在话语实践上完成了中华文化意象的互文性想象和文化认同正当性的连贯隐喻，在社会实践上传达了建设共有精神家园、构筑共享文化系统、凝聚共融文化认同的情感共性。

第五章深度剖析了跨文化传播中综艺节目受众文化身份认同建构的情感问题，主要体现在情境断裂、情感极化和话语危机三个方面，并提出跨文化传播中以综艺节目为媒介，建构受众文化身份认同的情感策略：拓宽文化认同的符号维度以实现情境共享，强化虚拟共同体的技术联结以实现情感共振，传达人类命运共同体的理念价值以实现话语共生。

At present, the phenomenon of cultural dispersion around the world has produced an unignorable issue of cultural identity, and the modern dispersed groups in dual or multi-cultural spaces are experiencing an identity crisis of cultural identity. The cultural program National Treasure on global social media platform, which serves as a benchmark for cultural programs, has attracted the pursuit of domestic and overseas audiences, providing a representative media sample for China's cross-cultural communication research. This study integrates relevant theoretical paradigms such as semiotics, narratology, and rhetoric, introduces cultural identity recognition theory, rhetoric theory, and discourse theory to analyze National Treasure on YouTube platform and its comments, providing theoretical and media practice value for revealing how emotions construct cultural identity recognition.

This study is divided into five chapters, namely the emotional logic of cultural identity recognition construction in cross-cultural communication, the emotional codes of the National Treasure: symbols, rhetoric, and meaning, the audience interaction and emotional effects of National Treasure on YouTube platform, the emotional discourse of cultural identity recognition construction in cross-cultural communication among audiences, and the emotional issues and strategies of cultural identity recognition construction in cross-cultural communication among audiences.

Chapter 1 traces the emotional logic of cultural identity construction in cross-cultural communication, systematically expounds the theoretical trajectory and realistic context of cultural identity construction in cross-cultural communication, tracing the emotional basis of cultural identity construction in cross-cultural communication from the perspectives of symbolic representation and identity reconstruction, and analyzing the emotional intercourse of cultural identity construction driven by media from the perspectives of media rituals, media platforms, and media languages.

Chapter 2 analyzes the text of the three seasons of National Treasure (a total of 30 episodes) from the perspectives of core symbolic codes, textual rhetoric, and meaning interpretation. Among them, the core symbolic codes include four types of scenes, characters, props, and auditory symbols. Based on Burke's identity rhetorical view, this chapter explores how the program achieves emotional resonance through the rhetoric of sympathetic identification in story contexts, how it forms an emotional alliance through the rhetoric of oppositional identity in war metaphors, and how it completes emotional mapping through unconscious identity rhetoric in relationship reconstruction. Under the emotional code encoding, the program is able to realize the meaning of cultural identity reconstruction through the creation of poetic atmosphere, the activation of common emotions through the awakening of archetypes, and the re-creation of cultural identity through the accumulation of symbols.

 Chapter 3 explores the audience interaction and emotional effects of the National Treasure on the YouTube platform. First, it statistically analyzes the quantitative data of audience interaction with the program to understand the general situation of interaction, and then captures 5010 effective comment text. Second, it uses the Jieba segmentation tool to statistically analyze the high-frequency words in audience comments, and then uses the SnowNLP sentiment analysis tool to analyze the distribution of audience comment emotional tendencies and positive/negative emotional words. Finally, it uses Gephi to draw a co-occurrence network diagram of high-frequency words and specific emotional words to further clarify the audience's emotional experience. The study found that the cultural narrative based on cultural relics can attract the audience's positive attention to Chinese culture, encourage the open expression of collective positive emotions, and complete the reconstruction of cultural identity from the program text context to the social cultural context in the process of individual emotional expression.

Chapter 4 conducts a discourse analysis of the comments on the National Treasure on the YouTube platform using the three-dimensional model of Falkowitz's discourse analysis. The study found that the audience of the program focused on expressing their cultural identity in terms of ethnic identity, dispersed identity, and heritage identity in their linguistic expression of cultural identity. They completed the intertextual imagination of Chinese cultural images and the consistent metaphor of cultural identity legitimacy in their discourse practice, and conveyed the emotional commonality of building a shared spiritual home, constructing a shared cultural system, and consolidating a shared cultural identity in their social practice.

Chapter 5 delves deeply into the emotional issues of constructing cultural identity among audiences in cross-cultural communication in variety shows, mainly manifested in three aspects of context disconnection, emotional polarization, and discourse crisis. It proposes emotional strategies for constructing audiences' cultural identity through variety shows as a medium: broadening the symbolic dimension of cultural identity to achieve context sharing, strengthening the technological connection of virtual communities to achieve emotional resonance, and conveying the concept of a community of human destiny to achieve discourse symbiosis.
