The Establishment of a Financial Crisis Early Warning System for Domestic Listed Companies Based on Two Neural Network Models in the Context of COVID-19

In the context of COVID-19, many companies have been affected by the financial crisis In order to carry out a comparative study on the accuracy of the company's financial crisis early warning method, this study used RPROP artificial neural network and support vector machine, with 162 listed companies' two-year panel financial indicator data as a model sample, and the test sample established a financial crisis early warning model The theory of comprehensive evaluation combining two kinds of neural network methods is put forward innovatively The predicted results can strengthen the supervision of the listed companies with risks by themselves and others and have important economic and social significance to ensure the stable operation of the listed companies, the securities market, and the national economy
