ABSTRACT

This article evaluates and explains the performance of a bankruptcy prediction model for non life insurance companies using the LightGBM algorithm combined with the SHAP method. With the impact of unexpected events such as the epidemic, the market share of the non life insurance industry continues to decline, and companies are facing enormous transformation pressure and even bankruptcy risks. Non life insurance companies not only ensure the property safety of policyholders, but are also closely related to the stability of the economy. Due to the limitations of traditional bankruptcy prediction methods with many assumptions, this paper uses feature engineering to clean, construct, screen, and extract high-dimensional non life insurance enterprise data, and constructs a global bankruptcy prediction model. Research has shown that models processed through feature engineering have better prediction accuracy than untreated models, especially in the F1 value, AUC value, recall rate, and other indicators of the feature construction group and feature selection group, which have significantly improved. The feature extraction group has the largest improvement in accuracy and recall rate. In addition, the interpretation results using the SHAP method show that the feature of "total liabilities and earnings" contributes the most to the prediction of the feature selection model, further verifying the interpretability and accuracy of the model.
