Abstract

Credit Scoring takes a prominent part in the finance of small and medium-sized enterprises (SMEs), and it is also an invaluable tool to predict credit default. However, due to the variety of market size, capital scale, and the limitations of Credit Scoring Model, it is difficult for SMEs to refer to large enterprises for Credit Scoring. And as an important reference, financial statements are insufficient and time window is inflexible, which would fail to make data reflect the enterprise's operating conditions correctly and timely, inaccurate credit prediction arising. Therefore, we offer an inspiring perspective to search elastic and time-independent evidence. Served as an indispensable basis of accounting in China, invoices take full notes on taxes of economic business, with more details about financial statements and more flexibility over periods, which can develop a sustainable approach to master the operation information of SMEs in time. To deal with invoice data of SMEs, we study influential variables under the first digit law inspired by Benford's law, apply machine learning techniques, and guide experiment by the construction of score card. It shows that our method formed by easy-to-accomplish steps is of applicability and effectiveness, to support powerfully the existing Credit Scoring system.
基于发票数据的中小企业信用评分新视角
信用评分在中小企业融资中占有重要地位,也是预测中小企业信用违约的重要工具。然而,由于市场规模、资金规模的差异以及信用评分模型的局限性,中小企业很难参照大企业进行信用评分。而且作为重要参考的财务报表不充分,时间窗口不灵活,不能使数据正确及时地反映企业的经营状况,导致信用预测不准确。因此,我们提供了一个鼓舞人心的视角来搜索弹性和时间无关的证据。发票是中国不可缺少的会计核算基础,它对经济业务的税收进行了充分的记录,财务报表的细节更详细,期间的灵活性更强,可以形成一种可持续的方法,及时掌握中小企业的经营信息。为了处理中小企业发票数据,我们在本福德定律的启发下研究第一位数定律下的影响变量,应用机器学习技术,并通过构建记分卡来指导实验。结果表明,该方法具有较强的适用性和有效性,能够有力地支持现有的信用评分系统。
