将人类行为的社会属性作为独立机制融入负面情绪传播动力学分析框架中, 能够更好地揭示社交网络中负面情绪的扩散过程, 为制定有效的舆情管理和危机应对策略提供科学依据。该文从外驱和内生两个维度, 探讨了社交网络中负面情绪传播不同于传统传染病传播的特点, 特别是社会强化与个体调节机制的作用。通过构建融合“社会强化-个体调节”双重影响的负面情绪异质传播阈值模型, 并结合仿真实验与实证分析, 系统阐明了双重机制对负面情绪传播动力学的关键影响。结果表明:提高个体的情绪调节能力以及降低社会强化强度, 有助于显著抑制负面情绪的大规模扩散。该文建议通过加强社会宣传和教育破除负面情绪传播链条, 强化媒体责任减少对负面情绪的过度渲染, 推广情绪教育、心理健康宣传、支持性社交网络建设以及在线情绪调节工具全面提升网民的情绪管理能力, 为社交网络负面情绪传播的治理提供切实可行的策略支撑。

Objective: This study integrates social attributes of human behavior as an independent mechanism within the analytical framework of negative emotion propagation dynamics. It aims to provide a comprehensive understanding of how negative emotions spread across social networks and establish a scientific basis for effective public opinion management and crisis response. Methods: This study examines the distinct mechanisms of social reinforcement and individual regulation that differentiate the spread of negative emotions in social networks from that of traditional infectious diseases. A heterogeneous propagation threshold model, named the SI-SEIR (social reinforcement and individual regulation susceptible-exposed- infected-recovered) model, incorporates a dual influence mechanism of "social reinforcement-individual regulation". First, we develop a non-Markovian negative emotion propagation model, considering social reinforcement and variations in individual emotion regulation abilities. We then extend the edge-based compartmental theory to determine the theoretical outbreak threshold and final propagation scale, including both continuous and discontinuous phase transitions. Extensive numerical simulations are conducted based on data from the Weibo network, using the Hubei Province Red Cross Society incident at the early stage of the COVID-19 pandemic to validate the effectiveness of the SI-SEIR model. Results: The findings show that individual emotion regulation abilities and social reinforcement significantly impact the spread of negative emotions. Improving individuals' emotion regulation ability and decreasing social reinforcement intensity can help effectively reduce large-scale outbreaks of negative emotions during public crises. Moreover, the network's topology feature significantly influences propagation outcomes. When individuals have relatively uniform emotion regulation abilities, a higher average degree of the network substantially raises the outbreak threshold, thereby reducing the likelihood of widespread diffusion. Increasing network heterogeneity can help increase the outbreak threshold and reduce the spread of negative emotions. Conclusions: Considering both social reinforcement and individual emotion regulation mechanisms is critical for accurately modeling and predicting the dynamics of negative emotion propagation in social networks.
