摘要 以降低信用风险为出发点,依据相关法规建立信用评价指标体系,基于TOPSIS-GRA构建信用评价模型,并针对文献研究中发现的数据处理及评价结果与实际不相符所导致的信用偏离问题,引入时间权重、横纵向比较均值差异调整基础信用值,使其符合发展变化,引入重置信用、诚信增益标度动态信用,使其符合实践逻辑。最后,通过对调研获取的样本数据进行改进前后评价结果的对比分析,结果显示改进后的评价消除了争议,使承制单位的优选排序更为准确。 In order to reduce the credit risk as a starting point,on the basis of relevant laws and regulations to establish credit evaluation index system,based on TOPSIS-GRA build credit evaluation model,and the actual credit problem caused by the data processing and evaluation result found in the literature research that do not match the actual situation,this paper introduces time weight,horizontal and vertical comparison of mean difference to adjust the basic credit value,and introduces dynamic credit reset credit,integrity gain scale to make it conform to practical logic.Finally,through the comparative analysis of the evaluation results before and after the improvement of the sample data obtained from the survey,the results show that the improved evaluation eliminates the dispute,and the optimization ranking of the contractor is more accurate.
