However, the complex internal and external environment has led to numerous risks for these companies in their operations. In order to achieve the goal of healthy and sustainable development for our country’s technology listed companies, it is necessary to conduct research on financial crisis warning. This article utilizes SPSS software to screen 21 financial indicator variables of 400 technology listed companies, determine model variables and discriminatory factors, and establish a modified Z-Score warning model for technology listed companies. The applicability of the model is tested using modeling and testing samples, and it is found that the model has a good warning effect on the occurrence of financial crises in China’s technology listed companies.展开更多
