Abstract: 【Purpose/significance】Weibo forwarding behavior is an important channel for the public to participate in the supervision of emergencies,and scientific and reasonable supervision and guidance are of great significance for accurate early warning and rapid re⁃sponse to emergencies【. Methods/process】The Weibo forwarding behavior in response to emergencies did not fully consider the short⁃comings of individual reposters.With the help of UTAUT model,combined with motivation theory,the three variables of type preference,source preference and engine rotation were introduced to construct emergencies-oriented model of the influencing factors of the event's Weibo user's forwarding behavior.Taking Sina Weibo as an example,through designing questionnaires and analyzing question⁃
naire data to verify the effectiveness of the construction of the influencing factor model,the fitting test of the influencing factor model is carried out【. Result/conclusion】The empirical results show that the CR value of effort expectation,community influence,source prefer⁃ence,and perceived cost on the path of forwarding willingness are all greater than 1.96,that is,it has a positive effect on forwarding will⁃ingness; forwarding willingness has a positive effect on the path of forwarding behavior The CR value of is greater than 1.96,that is,it has a positive effect on the reposting behavior.Suggestions on strengthening the supervision of Weibo reposting from government de⁃partments,relevant media and the public are put forward【. Innovation/limitation】In-depth research has been conducted on the repost⁃
ing behavior of Weibo users facing emergencies,but the survey subjects are not wide enough,and data analysis still has certain limita⁃tions.
