  ABSTRACT: China’s bond market is an emerging market. The number of bond defaults has been increasing in recent years, but the data set is severely imbalanced. Based on financial data of total 6731 corporate bond issuers which 50 bond issuers had defaulted, this paper uses the XGboost algorithm and an Over-sampling method named SMOTE to predict the default of bond issuers. The results show that the XGboost algorithm has advantages over the traditional algorithm in processing imbalanced data, and SMOTE is one of the effective methods to deal with imbalanced samples. Then, this is an effective way to predict the default risk of bond issuers in an emerging market.
