Abstract: 【Purpose/significance】To study the factors influencing the dissemination effect of rumor-refuting information in social net⁃works,enrich the theory of the effectiveness of rumor-defying information,and provide a basis for relevant departments to formulate strategies to improve the dissemination effect of rumor-refuting information.【Method/process】Based on the three-element theory of popularization,we summarize the influencing factors of the dissemination effect of rumor-refuting information,and verify the factors that affect the dissemination effect of rumor-refuting information through sentiment analysis,social network analysis and multiple re⁃gression analysis.【Result/conclusion】The number of fans,emotional tendencies,the way of dispelling rumors of "truth statement" and
"direct rebuttal + truth statement",originality,"text + pictures",leisure time,network size,network density and average path length have a significant impact The number of comments and reposts of the rumor-refuting information; the number of reposts in the rumorrefuting information containing the @ symbol positively affects the number of comments containing the link.【Innovation/limitation】Based on the popular three-element theory to refine the influencing factors of the dissemination effect of rumor-refuting information in social networks,and consider group factors,use social network data to conduct empirical research to provide reference for subsequent related research, but this article does not consider it in terms of platform factors and fans’personal attributes, further research is needed in the follow-up research.
