Abstract: [Purpose/Significance] When emergencies occur, the information environment becomes complex, users' emotions are strongly affected, and the social mentality fluctuates. This situation also poses new requirements for the management of network public opinion. It is urgent to actively and correctly manage the current social mentality. The research on the current social mentality mainly focuses on the macro level, while the micro-user emotion and the macro-network social mentality need to be further explored. Therefore, it is necessary to explore the fine-grained influencing factors of the network social mentality in public emergencies, so as to promote the effective response to public emergencies in China and manage social mentality. [Method/Process] The meta-synthesis method is used to formulate a reasonable retrieval strategy. Based on the mainstream databases at home and abroad, the literature is screened by topic, and the quality of related topic literature is evaluated to obtain effective literature and use it as the original data. Through the form of three-level coding, the included literature was interpreted, translated and aggregated to test the reliability and validity of the research results and confirm the validity of the results. This paper summarizes the key variables and implicit relations of the existing research results, and constructs a comprehensive and micro-theoretical framework of the influencing factors of network social mentality in public emergencies. The relationship between the dimensions and the main categories in the model was analyzed. [Results/Conclusions] The study finally obtained 90 initial concepts, 31 categories and 13 main categories, which were summarized into a model of influencing factors composed of four dimensions: user, event, government and social environment. As the main body and direct cause of the change of network social mentality, users and events are the core objects of network social mentality management. As the external environment for the change of network social mentality, society and government play an important role in the management and standardization of network social mentality. The theoretical model framework can provide some guidance and reference for promoting public emergency response and social mentality management. It is also of great significance for the study of network social mentality and user emotion. There are still some shortcomings in the article. The research object of this paper has not yet been more official and unified. The definition is a self-summary based on literature reading. In addition, due to the specificity of the research object, there may be a problem of incomplete literature search. In the future research, the management model will be further explored in combination with the development of practice, and the model framework will be revised and expanded.
