The dissemination of information and the adoption of immunization behaviors are vital for preventing infection during epidemics. Positive and negative information have different influences on the decision to accept immunization behaviors, and individuals make decisions about whether to accept immunization based on both subjective cognizance and objective environmental factors. A three-layer propagation model is proposed to explore the co-evolutionary dynamics of competitive information, immunization behavior, and epidemics in multiplex networks. We consider the competitive transmission of positive and negative information under the effect of individual cognitive preference and the effect of the subjective cognizance and objective environmental factors. For the objective environmental factors, the Prospect Theory is introduced to describe the risk-related costs. Furthermore, we investigate the local group immunity phenomenon. Utilizing the MMCA (microscopic Markov chain approach) for theoretical analysis, our findings indicate that the dynamics of epidemic transmission can indeed undergo multi-stage phase transitions when there exists a competing propagation of positive and negative information. Improving individual cognitive preference for positive information is essential for making the right judgments when engaging in the immunization game process and reducing the epidemic transmission scale. In addition, individuals are encouraged to reduce the free-rider strategy and adopt immunization behavior timely during epidemic transmission, as this contributes to overall emergency management.

多重网络中信息、行为和流行病的协同进化模型：结合主观和客观因素


信息的传播和免疫接种行为的采用对于在流行病期间预防感染至关重要。正面和负面信息对接受免疫接种行为的决定有不同的影响，个体根据主观认知和客观环境因素做出是否接受免疫的决定。提出了一个三层传播模型来探索多重网络中竞争信息、免疫行为和流行病的协同进化动力学。我们考虑了在个体认知偏好以及主观认知和客观环境因素的影响下，正面和负面信息的竞争传递。对于客观环境因素，引入了前景理论来描述与风险相关的成本。此外，我们研究了局部群体免疫现象。利用 MMCA（微观马尔可夫链方法）进行理论分析，我们的研究结果表明，当存在正负信息的竞争传播时，流行病传播的动力学确实可以经历多阶段的相变。提高个体对积极信息的认知偏好对于在参与免疫游戏过程中做出正确判断和降低疫情传播规模至关重要。此外，鼓励个人减少搭便车策略，并在疫情传播期间及时采取免疫接种行为，因为这有助于整体应急管理。
