In this paper, from the perspective of capital flow, the insurance company\u2019s capital flow is regarded as a dynamic system, the stochastic differential equations model is established to describe its flow characteristics, and the existence of positive equilibrium point of the system is proved, as well as the conditions of stability at equilibrium point, that is, the requirements of the insurance company\u2019s solvency. Furthermore, by using the numerical simulation method, we get the strategy of insurance companies to deal with the solvency shortage when facing the change of external environment, and the strategy of insurance company to deal with solvency shortage is obtained.<\/jats:p>","DOI":"10.1155\/2021\/5594619","type":"journal-article","created":{"date-parts":[[2021,4,16]],"date-time":"2021-04-16T22:06:24Z","timestamp":1618610784000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":1,"title":["Solvency Evaluation Model of Insurance Company Based on Stochastic Differential Equation"],"prefix":"10.1155","volume":"2021","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-9687-783X","authenticated-orcid":false,"given":"Kai","family":"Wang","sequence":"first","affiliation":[]},{"ORCID":"https:\/\/orcid.org\/0000-0001-8155-5515","authenticated-orcid":false,"given":"Ling","family":"Zhu","sequence":"additional","affiliation":[]}],"member":"311","published-online":{"date-parts":[[2021,4,16]]},"reference":[{"key":"e_1_2_12_1_2","doi-asserted-by":"publisher","DOI":"10.1111\/j.1540-6296.2007.00106.x"},{"key":"e_1_2_12_2_2","doi-asserted-by":"publisher","DOI":"10.1080\/1351847x.2020.1850499"},{"key":"e_1_2_12_3_2","doi-asserted-by":"publisher","DOI":"10.1017\/S135732172000001X"},{"key":"e_1_2_12_4_2","doi-asserted-by":"publisher","DOI":"10.1017\/S1357321718000302"},{"key":"e_1_2_12_5_2","doi-asserted-by":"publisher","DOI":"10.1017\/s1357321717000241"},{"key":"e_1_2_12_6_2","doi-asserted-by":"publisher","DOI":"10.3846\/tede.2019.6213"},{"key":"e_1_2_12_7_2","first-page":"13","article-title":"The standard formula of solvency II: a critical discussion","volume":"11","author":"Scherer M.","year":"2020","journal-title":"European Actuarial Journal"},{"key":"e_1_2_12_8_2","doi-asserted-by":"publisher","DOI":"10.1057\/gpp.2014.10"},{"key":"e_1_2_12_9_2","doi-asserted-by":"publisher","DOI":"10.1017\/s1748499518000027"},{"key":"e_1_2_12_10_2","first-page":"123","article-title":"Portfolio optimization under solvency II: a multi-objective approach incorporating market views and real-world constraints","volume":"1","author":"Di Francesco M.","year":"2021","journal-title":"Decisions in Economics and Finance"},{"key":"e_1_2_12_11_2","doi-asserted-by":"crossref","unstructured":"Fernandez-ArjonaL.
