The market can be regarded as a complex network whose nodes are stocks connected by edges that signify their correlation strength. Since the market is a strongly nonlinear system, it is difficult to measure the macroscopic stability and depict market fluctuations in time. In this article, we use a geometric measure derived from discrete Ricci curvature to capture the higher-order nonlinear architecture of financial networks. In order to confirm the effectiveness of our method, we use it to analyze the CSI 300 constituents of China\u2019s stock market from 2005 to 2020 and the systemic stability of the market is quantified through the network\u2019s Ricci-type curvatures. Furthermore, we use a hybrid model to analyze the curvature time series and predict the future trends of the market accurately. As far as we know, this is the first article to apply Ricci curvature to forecast the systemic stability of China\u2019s stock market, and our results show that Ricci curvature has good explanatory power for the market stability and can be a good indicator to judge the future risk and volatility of China\u2019s stock market.<\/jats:p>","DOI":"10.1155\/2023\/2361405","type":"journal-article","created":{"date-parts":[[2023,1,17]],"date-time":"2023-01-17T19:50:09Z","timestamp":1673985009000},"page":"1-12","source":"Crossref","is-referenced-by-count":5,"title":["Stability of China\u2019s Stock Market: Measure and Forecast by Ricci Curvature on Network"],"prefix":"10.1155","volume":"2023","author":[{"given":"Xinyu","family":"Wang","sequence":"first","affiliation":[{"name":"School of Science, China Agricultural University, Beijing 100091, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-4763-4863","authenticated-orcid":true,"given":"Liang","family":"Zhao","sequence":"additional","affiliation":[{"name":"School of Mathematical Sciences, Key Laboratory of Mathematics and Complex Systems of MOE, Beijing Normal University, Beijing 100875, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Ning","family":"Zhang","sequence":"additional","affiliation":[{"name":"School of Finance, Chinese Fintech Research Center, Central University of Finance and Economics, Beijing 102206, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Liu","family":"Feng","sequence":"additional","affiliation":[{"name":"School of Finance, Chinese Fintech Research Center, Central University of Finance and Economics, Beijing 102206, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Haibo","family":"Lin","sequence":"additional","affiliation":[{"name":"School of Science, China Agricultural University, Beijing 100091, China"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","reference":[{"key":"1","doi-asserted-by":"publisher","DOI":"10.2307\/3440882"},{"key":"2","doi-asserted-by":"publisher","DOI":"10.5089\/9781451857283.001"},{"key":"3","doi-asserted-by":"publisher","DOI":"10.1111\/0022-1082.00409"},{"key":"4","doi-asserted-by":"crossref","DOI":"10.1017\/CBO9780511753893","volume-title":"Theory of Financial Risk and Derivative Pricing From Statistical Physics to Risk Management","author":"J.
