Abstract: 【Purpose/significance】In recent years, the frequent occurrence of reversal news has had a significant impact on the genera?
tion and development of social public opinion. This paper explores the generation mechanism of reversal news public opinion enthusi?
asm, in order to provide suggestions and strategies for weakening the focus of reversal news public opinion.【Method/process】Based
on the social combustion theory, combined with the existing literature and the analysis of recent news reversal cases, this paper puts
forward interest demands from three aspects: "combustion substances", "combustion accelerants" and "ignition temperature" , media
participation, news anomie, issue type, reversal intensity and reversal times as the six antecedent conditions for the generation of rever? sal news public opinion heat, and use the clear set qualitative comparative analysis method to generate the path of high public opinion heat of reversal news. Explore.【Result/conclusion】The study found that news anomie as "accelerator" is a necessary condition for re? versal news to generate high public opinion enthusiasm, and media participation as the core condition has a certain moderating effect on the public opinion enthusiasm of reversal news; and the number of reversals cannot be used alone as the "ignition temperature" to lead to the generation of high-profile public opinion, but require a synergistic effect of the two; the inversion intensity as the "ignition temperature" has no significant impact on the popularity of public opinion.【Innovation/limitation】This paper needs more cases to verify the generaliza-bility of the findings in the future.
