Multiview Graph Learning for Small- and Medium-Sized Enterprises' Credit Risk Assessment in Supply Chain Finance

Cong Wang, Fangyue Yu, Zaixu Zhang, Jian Zhang, Baogui Xin
2021 Complexity  
Compared with traditional credit risk assessment models, the supply chain relationship, credit condition of SME, and core enterprises should all be considered to rate SME credit risk in SCF.  ...  SME credit risk assessment is a critical part in the SCF system. The diffusion of SME credit risk may cause serious consequences, leading the whole supply chain finance system unstable and insecure.  ...  However, it cannot reflect the credit risk when a company suffered losses in the first year. e Z-score model [34] is adopted to define the credit risk, which is widely used in enterprise financial health  ...

Benjamin P.-C Yen, Bingcong Zeng
2011 2011 44th Hawaii International Conference on System Sciences
