Abstract: Taking 12 domestic public health emergencies as samples, based on the three-dimensional linkage analysis framework of “government media public”, this paper empirically analyzes the influencing factors of government information disclosure in public health emergencies and their complex causal logic relationships by using the qualitative comparative analysis method (QCA). The research shows that six single conditional variables, such as technical level, official cognition, communication channel, media responsibility, public sentiment, and public demand, are not enough to constitute the necessary conditions for government information disclosure in public health emergencies, which is the result of the combination of multiple conditions; Further configuration analysis found that efficient and transparent government information disclosure includes three key condition configuration paths: technology enabled, media driven and multi effect. Based on this, suggestions are put forward to optimize the government information disclosure in public health emergencies in the future from the aspects of changing the governance concept, activating the science and technology engine, and improving public opinion recognition.

Key words: public health emergencies, publicity of government information, influencing factors, conditional configuration
