Based on the four factors involved in the spread of public opinion, the public health emergency, netizen, network media, and government, Brusselator model, and entropy method were applied to calculate the positive and negative entropy\u2014to verify whether the Internet public opinion system is a dissipative structure. This study verified four evolution mechanisms in Internet public opinion diffusion, among which the trigger point of entropy-control occurred in the germination mechanism, the entropy-controlled disposal point occurred in the outbreak and fluctuating mechanism, and then became latency in the elimination mechanism. It provides a theoretical reference for the government to judge the stage of such diffusion and improve the governance ability of the opinion mentioned above.<\/jats:p>","DOI":"10.3389\/fpubh.2021.731080","type":"journal-article","created":{"date-parts":[[2021,10,15]],"date-time":"2021-10-15T01:35:28Z","timestamp":1634261728000},"update-policy":"https:\/\/doi.org\/10.3389\/crossmark-policy","source":"Crossref","is-referenced-by-count":16,"title":["Internet Public Opinion Diffusion Mechanism in Public Health Emergencies: Based on Entropy Flow Analysis and Dissipative Structure Determination"],"prefix":"10.3389","volume":"9","author":[{"given":"Wanlian","family":"Li","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Feng","family":"Zeng","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Wei","family":"Zhou","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Zhishao","family":"Chen","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1965","published-online":{"date-parts":[[2021,10,15]]},"reference":[{"key":"B1","doi-asserted-by":"publisher","first-page":"9235","DOI":"10.3390\/ijerph17249235","article-title":"A New geo-propagation model of event evolution chain based on public opinion and epidemic coupling","volume":"17","author":"Zhang","year":"2020","journal-title":"Int J Environ Res Public Health"},{"key":"B2","doi-asserted-by":"publisher","first-page":"200","DOI":"10.3389\/fpubh.2015.00200","article-title":"Capturing public opinion on public health topics: a comparison of experiences from a systematic review, focus group study, and analysis of online, user-generated content","volume":"3","author":"Giles","year":"2015","journal-title":"Front Public Health"},{"key":"B3","doi-asserted-by":"publisher","first-page":"179620","DOI":"10.1155\/2014\/179620","article-title":"Information spread of emergency events: path searching on social networks","volume":"2014","author":"Dai","year":"2014","journal-title":"ScientificWorldJournal"},{"key":"B4","doi-asserted-by":"publisher","first-page":"2788","DOI":"10.3390\/ijerph17082788","article-title":"Using social media to mine and analyze public opinion related to COVID-19 in China","volume":"17","author":"Han","year":"2020","journal-title":"Int J Environ Res Public Health."},{"key":"B5","doi-asserted-by":"publisher","first-page":"e19455","DOI":"10.2196\/19455","article-title":"Online information exchange and anxiety spread in the early stage of the novel coronavirus (COVID-19) outbreak in South Korea: structural topic model and network analysis","volume":"22","author":"Jo","year":"2020","journal-title":"J Med Internet Res"},{"key":"B6","doi-asserted-by":"publisher","first-page":"5077","DOI":"10.3390\/ijerph17145077","article-title":"Digital surveillance for monitoring environmental health threats: a case study capturing public opinion from twitter about the 2019 Chennai water crisis","volume":"17","author":"Xiong","year":"2020","journal-title":"Int J Environ Res Public Health"},{"key":"B7","doi-asserted-by":"publisher","first-page":"275","DOI":"10.1108\/JKM-07-2015-0296","article-title":"Managing extracted knowledge from big social media data for business decision making","volume":"21","author":"He","year":"2017","journal-title":"J Knowl Manage."},{"key":"B8","unstructured":"The 44"},{"key":"B9","doi-asserted-by":"publisher","first-page":"374","DOI":"10.1159\/000272417","article-title":"Prigogine's model for self-organization in non-equilibrium systems","volume":"21","author":"Brent","year":"1978","journal-title":"Human Dev."},{"key":"B10","first-page":"248","article-title":"Self-organization and dissipative structures","volume":"16","author":"Allen","year":"1990","journal-title":"Techn Phys Lett."},{"key":"B11","doi-asserted-by":"publisher","first-page":"165","DOI":"10.1016\/S0921-8009(00)00225-1","article-title":"Entropy and economic processes - physics perspectives","volume":"36","author":"K\u00e5berger","year":"2001","journal-title":"Ecol Econ."},{"key":"B12","doi-asserted-by":"crossref","first-page":"1695","DOI":"10.1063\/1.1668896","article-title":"Symmetry breaking instabilities in dissipative systems II","volume":"48","author":"Prigogine","year":"1968","journal-title":"J Chem Phys."},{"key":"B13","first-page":"34","article-title":"The management entropy research of enterprise network based on brusselator model","volume":"1","author":"Yu","year":"2014","journal-title":"J.
