Abstract:With the rapid development of E-commerce,some fundamental issues such as payment and logistics distribution are solved gradually and E-commerce credit risk between buyers and sellers becomes a bottleneck problem restricting the development of E-commerce.For this purpose,an E-commerce credit risk early-warning indicator system is first constructed in terms of the previous studies.Then a least squares proximal support vector regression model is proposed for E-commerce credit risk early-warning. Using a public available dataset on E-commerce credit risk,empirical experiments are finally conducted. Based on some experimental results,some different early-warning management strategies are presented for E-commerce credit risk management.
Keywords:E-commerce credit risk  credit risk early-warning  least squares proximal support vector regression
