| Abstract:The management discussion and analysis(MD&A) in the annual report is an important part of corporate information disclosure. This paper constructs two textual feature indexes, superficial tone (STONE) and implicit propensity for default (IPD) to quantify MD&A text in the annual report, and proposes a financial default prediction method for listed companies based on XGBoost model. This method has achieved a good prediction effect on the financial default of listed companies. According to feature importance ranking, the relationship between features and financial defaults is mined, and the sensitivity analysis is used to verify the effectiveness of STONE and IPD. |
