[Purpose/significance] Public Health Emergency of International Concern stimulates the willingness of in?
dividual information sharing. Due to the uncertainty of the event, individual panic rises, which is easy to lead to irratio?
nal individual information sharing behavior and is not conducive to the prevention, control, and governance of PHEIC.
[Method/process] Through the questionnaire survey method, the empirical analysis of342 valid samples uses a hybrid
method based on Structural Equation Modeling (SEM) and fuzzy set qualitative comparative analysis method (fsQCA) to
explore the formation mechanism and influence of social media users' information sharing behavior in this situation
model. [Result/conclusion] In the terms of the net effect of a single influencing factor, self-expression, privacy con ?
cerns, emotional support, social responsibility, and intergroup emotional infection have significant effects on users' in?
formation sharing behavior to varying degrees. In terms of the research on the configuration perspective, the combina ?
tions of influence factors show that there is an interaction between the internal and external dimensions of attention,
and the perceived cost and the perceived benefit-cost have an asymmetric causal relationship. Finally, according to the
individual information-sharing behavior under PHEIC, the corresponding countermeasures and suggestions are given
from the internal and external perspective, guiding the public to participate in PHEIC rationally,protecting personal pri ?
vacy while improving the effectiveness of information dissemination, and further promoting the orderly prevention and
control of PHEIC.
