ABSTRACT:
With the rapid development of P2P (peer-to-peer) online lending industry,
how to effectively evaluate the borrowers’ credit risk in the platform has
drawn more and more attention. In this paper, we propose a borrower credit
risk assessment index system that includes basic information, work information,
credit information, asset information, loan information and audit certification
information, and come up with a credit risk assessment model that
combines Gradient Boosting Decision Trees (GBDT) and support vector machine
(SVM). Then, we select the data of P2P lending platform to carry out
the empirical analysis of the credit risk assessment, and compare with the
common four kinds of single prediction models such as logic regression (LR),
artificial neural network (ANN), SVM and clustering algorithm. The results
show that the increase of audit certification information helps to improve the
forecasting effect of the model, and the credit risk assessment model of P2P
lending platform based on GBDT and SVM has higher prediction accuracy
and stability.
