传统的企业信用水平分析方法多从企业规模、经营地、行业类别、注册与实缴资本等特征属性出发,缺少基于海量关联数据的深入分析。为了解决这个问题,采集、清洗了大量数据,建立了包含400多万家企业的有向投资网络,其中存在各类失信行为的企业有近26万家。研究结果显示,企业失信行为存在明显的“网络效应”,目标企业的股东或者投资企业若存在失信行为,则目标企业发生失信的风险远远大于平均值。基于此,提出了简单的预测企业失信行为的算法,其精确性远远超过了不考虑网络效应的回归方法。
Previous enterprise credit level analysis mainly focused on the features including enterprise size
place of operation
industry category
registration and paid-in capital
and lacked in-depth analysis based on massive data.A directed investment network consisted of more than 4 million enterprises was built up
among which nearly 260 000 enterprises have various discredited behaviors.The results show that there is an obvious "network effect" in the discredited behaviors of enterprises.If the target enterprise's shareholders or its invested enterprises have discredited behaviors
the risk of having discredited behaviors of the target enterprise is far greater than the average.Based on this
a simple generalized linear regression algorithm was proposed to predict the discredited behaviors of enterprises
which is far more accurate than the regression method without considering the network effect.
