This paper delves into the core entities in the diffusion process of internet financial public opinions, including financial institutions, governments, media, and investors, and models the behavioral characteristics of these entities in the diffusion process. On this basis, we comprehensively use the multi-agent model and the SIR model to construct a dynamic evolution model of internet financial public opinion. We conduct a simulation analysis of the impact effects and interaction mechanisms of multi-agent behaviors in the financial market on the evolution of internet financial public opinion. The research results are as follows. Firstly, the financial institutions\u2019 digitalization levels, government guidance, and the media authority positively promote the diffusion of internet financial public opinion. Secondly, the improvement of investors\u2019 financial literacy can inhibit the diffusion of internet financial public opinion. Thirdly, under the interaction of multi-agent behaviors in the financial market, the effects of financial institutions\u2019 digitalization level and investors\u2019 financial literacy are more significant, while the effects of government guidance and media authority tend to converge.<\/jats:p>","DOI":"10.3390\/info15080433","type":"journal-article","created":{"date-parts":[[2024,7,25]],"date-time":"2024-07-25T13:10:28Z","timestamp":1721913028000},"page":"433","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":2,"title":["Dynamic Evolution Model of Internet Financial Public Opinion"],"prefix":"10.3390","volume":"15","author":[{"given":"Chao","family":"Yu","sequence":"first","affiliation":[{"name":"School of Cyber Science and Engineering, Southeast University, Nanjing 211189, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Jianmin","family":"He","sequence":"additional","affiliation":[{"name":"School of Economics and Management, Southeast University, Nanjing 211189, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-4728-7040","authenticated-orcid":false,"given":"Qianting","family":"Ma","sequence":"additional","affiliation":[{"name":"School of Economics and Management, Southeast University, Nanjing 211189, China"},{"name":"College of Finance, Nanjing Agricultural University, Nanjing 210095, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Xinyu","family":"Liu","sequence":"additional","affiliation":[{"name":"College of Finance, Nanjing Agricultural University, Nanjing 210095, China"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2024,7,25]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"608","DOI":"10.1016\/j.micinf.2020.11.001","article-title":"Digging the rabbit hole, COVID-19 edition: Anti-vaccine themes and the discourse around COVID-19","volume":"22","author":"Smith","year":"2020","journal-title":"Microbes Infect."},{"key":"ref_2","doi-asserted-by":"crossref","first-page":"123","DOI":"10.1007\/s43076-022-00192-5","article-title":"The negative impact of social media during COVID-19 pandemic","volume":"31","author":"Lelisho","year":"2023","journal-title":"Trends Psychol."},{"key":"ref_3","doi-asserted-by":"crossref","first-page":"102796","DOI":"10.1016\/j.ipm.2021.102796","article-title":"Multi-stage Internet public opinion risk grading analysis of public health emergencies: An empirical study on Microblog in COVID-19","volume":"59","author":"Liu","year":"2022","journal-title":"Inf.
