Abstract In this study, a system of stakeholders of public health emergencies is constructed based on stakeholder theory, which consists of thirteen types. The life cycle of emergencies is divided into five phases, based on life cycle theory. The Latent Dirichlet Allocation (LDA) model is used to analyze and compare the similarities and differences of topics about the Middle East Respiratory Syndrome (MERS) outbreak on Sina Weibo and WeChat platforms. The concerns and evolutionary patterns of stakeholders in the different life cycle phases are characterized and summarized. The findings can help public health emergency administrators take corresponding measures for specific populations and alleviate the negative impact of public emergencies.
