Large and medium-sized companies will also play a key role in the recovery of growth after the outbreak. Therefore, it is particularly important to pay attention to the impact of the epidemic on large and medium-sized companies and on the investment and financing of companies. Firstly, the structure of the network model of data analysis is designed in this paper, including the design of the network level, the selection of the number of neurons in each level, the determination of the initial weight and other related parameters. According to the design of network structure, the evaluation model of investment and financing of listed companies is established. Python is used to preprocess the data and train the sample data. By comparing the data processed by two training methods, the optimal network classification model is selected. The experimental results show that the proposed method can improve the effectiveness of investment and financing decisions of listed companies.<\/jats:p>","DOI":"10.3233\/jifs-189285","type":"journal-article","created":{"date-parts":[[2020,9,15]],"date-time":"2020-09-15T09:17:50Z","timestamp":1600161470000},"page":"8877-8886","source":"Crossref","is-referenced-by-count":11,"title":["Big data analysis and empirical research on the financing and investment decision of companies after COVID-19 epidemic situation based on deep learning"],"prefix":"10.1177","volume":"39","author":[{"given":"Jing","family":"Jing","sequence":"first","affiliation":[{"name":"Department of Economic Management, Henan Polytechnic Institute, Nangyang, Henan, China"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"179","reference":[{"issue":"6","key":"10.3233\/JIFS-189285_ref1","doi-asserted-by":"crossref","first-page":"1","DOI":"10.3233\/JIFS-18810","article-title":"AWBING plus algorithm for generic object proposal generation","volume":"36","author":"Liu","year":"2019","journal-title":"Journal of Intelligent and Fuzzy Systems"},{"issue":"1","key":"10.3233\/JIFS-189285_ref2","first-page":"35","article-title":"Decision models for capital investment and financing decisions in hospitals","volume":"15","author":"Vraciu","year":"1980","journal-title":"Health Services Research"},{"issue":"1","key":"10.3233\/JIFS-189285_ref3","doi-asserted-by":"crossref","first-page":"134","DOI":"10.2307\/3180313","article-title":"A Method for Analyzing the Effect of Taxes and Financing on Investment Decisions: Comment","volume":"53","author":"Devino","year":"1971","journal-title":"American Journal of Agricultural Economics"},{"issue":"APR.1","key":"10.3233\/JIFS-189285_ref4","doi-asserted-by":"crossref","first-page":"1078","DOI":"10.1016\/j.jclepro.2019.01.119","article-title":"Investment decision-making optimization of energy efficiency retrofit measures in multiple buildings under financing budgetary restraint","volume":"215","author":"He","year":"2019","journal-title":"Journal of Cleaner Production"},{"issue":"1-2","key":"10.3233\/JIFS-189285_ref5","doi-asserted-by":"crossref","first-page":"88","DOI":"10.1504\/IJTM.2006.009449","article-title":"Strategic and Investment Behaviour in the German and Israeli Venture Capital Industries: A Comparison with the USA","volume":"34","author":"Grichnik","year":"2006","journal-title":"International Journal of Technology Management"},{"issue":"2","key":"10.3233\/JIFS-189285_ref6","doi-asserted-by":"crossref","first-page":"209","DOI":"10.1007\/BF02936328","article-title":"Applications of game theory in finance and managerial accounting","volume":"2","author":"Migdalas","year":"2002","journal-title":"Operational Research"},{"issue":"4","key":"10.3233\/JIFS-189285_ref9","first-page":"59","article-title":"Real Option Analysis on Interaction Effects and Harmonizing Decisions between Investment and Financing","volume":"25","author":"Xing","year":"2007","journal-title":"Systems Engineering"},{"issue":"7","key":"10.3233\/JIFS-189285_ref10","doi-asserted-by":"crossref","first-page":"3807","DOI":"10.1016\/j.enpol.2010.03.001","article-title":"Risk adjusted financial costs of photovoltaics","volume":"38","author":"Szabo","year":"2010","journal-title":"Energy Policy"},{"issue":"6","key":"10.3233\/JIFS-189285_ref11","doi-asserted-by":"crossref","first-page":"611","DOI":"10.1016\/S0959-6526(02)00103-8","article-title":"Special issue on cleaner production financing","volume":"11","author":"Huhtala","year":"2003","journal-title":"Journal of Cleaner Production"},{"issue":"1","key":"10.3233\/JIFS-189285_ref12","doi-asserted-by":"crossref","first-page":"18","DOI":"10.1061\/(ASCE)1076-0342(2001)7:1(18)","article-title":"BOT-Based Approaches to Infrastructure Development in China","volume":"7","author":"Zhang","year":"2001","journal-title":"Journal of Infrastructure Systems"},{"issue":"12","key":"10.3233\/JIFS-189285_ref14","doi-asserted-by":"crossref","first-page":"1","DOI":"10.1080\/14697688.2015.1069386","article-title":"Risk-Sensitive Investment Management","volume":"15","author":"Danilova","year":"2015","journal-title":"Quantitative Finance"},{"issue":"1","key":"10.3233\/JIFS-189285_ref15","first-page":"27","article-title":"Workshop 2: multi-modal infrastructure investment decision-making","volume":"96","author":"Kriger","year":"1997","journal-title":"Entomological News"}],"container-title":["Journal of Intelligent &amp;
