气候变化是一个兼具全球性与地方性、长期性与突发性、系统性与随机性的风险类型，涉及生态环境和社会经济发展诸多方面。当前气候风险呈现出愈演愈烈的趋势，提升全社会气候风险适应能力迫在眉睫。过往全国性调查显示，公众在气候风险上呈现“高关心、浅认知”的特点，在气候行动上呈现“高焦虑、低效能”的特征，如何增强公众气候风险感知、提升气候行动效能，是当前面向公众进行气候风险传播的主要目标，更是提升全社会气候风险韧性的重要一环。有关气候传播效果的影响因素，现有研究普遍证实了媒体框架、情绪唤起，以及受众文化观念的显著影响。本研究从传播效果的角度切入，探究以上三个因素对公众风险感知和行动效能的影响。通过2 ? 2组间实验设计（高/ 低情境卷入框架 ? 情感/ 信息诉求框架），以线上问卷形式随机分发上述4组报道材料，并收集参与者在操纵检验问题，以及风险感知和行动效能相关问题上的回答，探究不同框架组合是否在影响参与者风险和效能感知上有显著差异（实验一）；研究在操纵检验问题后，设置负面和正面情绪唤起的相关问题，以探究在报道框架影响参与者感知的过程中，情绪是否起到中介或调节的作用（实验二）；研究还在问卷初始部分设置量表矩阵问题收集参与者的集体主义、自我超越和不确定性容忍度三个文化观念倾向，探究文化观念、风险感知和行动效能间的关系（实验三），以洞察个体的内在观念和受外部刺激影响产生波动的风险感知是否以及如何共同影响行动效能。结果显示，相较于信息诉求框架，情感诉求框架在增强公众对气候风险的感知程度上，具有更为显著的正向效应；相比低情境卷入框架，高情境卷入框架对公众气候行动效能水平具有更强的正向预测作用。愤怒在“诉求类型框架影响风险感知”的关系中起到遮掩效应，希望在“情境卷入框架影响行动效能”的关系中起到正向调节作用。集体主义、自我超越、不确定性容忍度正向影响风险感知，风险感知正向影响行动效能，即气候风险感知在文化观念影响行动效能的关系中起到正向中介作用。研究明确了媒介框架的情感或信息密度以及个人相关性对传播效果的影响，细化了不同情绪类型的影响机制，支持了“风险文化理论”在我国文化社会语境下的适用性。

Climate change poses global and local, long-term and immediate, systemic and idiosyncratic risks, affecting multiple aspects of ecology, environment, and socio-economic development. Current trends show escalating climate risks, urging the need to enhance societal resilience in the face of climate change. National surveys on public attitude towards climate change show that most people exhibit high concern but limited understanding of the immediate hazards, coupled with high anxiety and low efficacy in climate action. Therefore, two of the critical objectives in climate communication are forming climate risk perception and building confidence in participation, which potentially enhance climate resilience of the society.There’s ample research indicating that media frames, emotions and cultural values significantly influence risk perception and mitigation efficacy. Using an empirical approach, this study employed a 2 × 2 factorial research design to examine the effect of different frameworks (high/low situational involvement × emotional/informational appeal) on participants‘ risk perception and mitigation efficacy (Experiment 1), and to examine whether emotions take moderating and/ or mediating roles (Experiment 2). The way individuals’ cultural values might influence risk perceptions and efficacy was examined in Experiment 3.Results show that emotional appeal positively predicts climate risk perception, where angry exerts suppression effect, and that high situational involvement frame positively predicts mitigation efficacy, where hope plays a significant moderating role. Furthermore, cultural beliefs, including collectivism, self-transcendence, and uncertainty tolerance, positively influence risk perception, which in turn positively influence efficacy. This research illuminates how media frames and emotions impact communication outcomes, affirming the significance of the Cultural Theory of Risk within the cultural and social landscape of China.
