摘　　要：针对废弃混凝土处置再生行业参与主体信用评估问题,提出了一种基于行为特征的信用评估模型。基于所提出的动态信息上报框架获得非财务类数据;通过对上报数据进行挖掘分析获取行为特征信息,进而提取评估指标;建立信用模型,将信用评估过程中关键信息存储到区块链。实验结果表明,该信用评估模型具有良好的评估效果,可以有效识别行业领域内的风险主体。Aiming at the problem of credit evaluation of the participants in waste concrete disposal and recycling industry,a credit evaluation model based on behavior characteristics was proposed.Firstly,non-financial data is obtained based on the proposed dynamic information reporting framework.Secondly,behavioral characteristic information is obtained by mining and analyzing the reported data,and then evaluation indicators are extracted.Finally,a credit model is established,and key information in the credit assessment process is stored in the blockchain.The experimental results show that the proposed credit evaluation model has good evaluation effect and can effectively identify risk subjects in the industry field.
