 Corporate governance, fraud learning cycles, and financial fraud detection: Evidence from Chinese listed firmsJing Li Research in International Business and Finance, 2025, vol. 76, issue C Abstract: Corporate governance indicators play an important role in detecting financial fraud. Compared to the multilayer perceptron neural network (MLP NN) model, the extreme gradient boosting (XGBoost) model detects financial fraud more reliably, but suffers from a parameter search problem. An ant colony optimization algorithm can effectively optimize the model and increase its accuracy. Using data from 1660 Chinese listed firms between 2015 and 2021, adding corporate governance indicators considerably increased the XGBoost model's accuracy. Model optimization and empirical evidence show that fraud detection accuracy is higher in the early fraud learning cycle than in the most recent cycle. Moreover, the accuracy of detecting fraud is higher in the short fraud learning cycle than in the long cycle, while two years is the optimal fraud learning cycle. This study also analyzes the mechanisms through which corporate governance indicators affect financial fraud detection.
