Abstract: 【Purpose/significance】In the context of the Internet, social hot spot emerges in an endless stream, which can easily trigger
public opinion and rumor crisis due to high online attention. Public opinion and rumor have a close relationship when they evolve. By
analyzing the coupling mechanism of public opinion and rumor, it provides guidance for the network governance of social hotspot.
Through the analysis of the coupling mechanism of public opinion and rumors, we can give the network governance enlightenment of
social hot spot.【Method/process】This paper selects 28 social hot spots in the past four years, selects the prominent coupling samples from public opinion and rumors data, analyzes three types of coupling models visually, and reveals the coupling mechanism of network public opinion and rumors by using the internal and external circulation mechanism of actors, capital and habits in the field theory.【Result/conclusion】The paper reveals the mutual vibration and common change mechanism of the two fields coupling the evolution of public opinion and rumors, the rumor field inhibition and public opinion field counterattack mechanism of leading divergence cou? pling, the public opinion field leading and rumor field breaking mechanism of lagging divergence coupling. This study is of great signif? icance for the scientific judgment and accurate policy of online public opinions and rumors of social hot spot.【Innovation/limitation】Combined with multiple research methods to reveal the two-way interaction between public opinions and rumors, the theoretical re? search on the influencing factors of the coupling evolution of public opinions and rumors still needs to be strengthened.
