Financial Performance Evaluation of Listed Companies Based on Improved Catastrophe Progression Method——Take the express industry as an example

As China's express delivery industry plays an increasingly important role in the national economy, evaluating its financial performance has become an unavoidable issue for operators and investors. This paper constructs a financial performance evaluation index system for listed companies, and uses the entropy weight-Catastrophe progression method to evaluate the financial performance of listed companies in china's express delivery industry from 2017 to 2020, and makes a brief analysis of the evaluation results. Studies have shown that it is feasible to evaluate the financial performance of listed companies through the improved catastrophe progression method. The evaluation results can reflect the weakness in the development of companies and provide references for operation and investment decisions.
