“…The information spreading model evolved from the COVID-19 spreading model (SI, SIR, SIRS, SIS) ( van den and Watmough, 2000 , DALEY and KENDALL, 1965 , Ren and Wang, 2014 , Boguñá and Castellano, 2013 , Song et al, 2002 , Wen-Jie and Xing-Yuan, 2013 ). Through extensive research on the spreading dynamics of complex networks, it is found that the structural characteristics and propagation mechanism of networks have great influence on the threshold of information burst ( Tunc and Shaw, 2014 , Zhang et al, 2015 , Pastor-Satorras and Vespignani, 2001 , Shi et al, 2020 , Nian and Diao, 2019 , Chao et al, 2014 , Xu et al, 2015 , Guo, 2012 ). On the one hand, there is evidence that the heterogeneity of level distribution reduces the prevalence threshold ( Boguñá and Castellano, 2013 ), but the Heterogeneity of the edge weight suppresses the outbreak of popularity ( Wang et al, 2014 ).…”
