摘　　要：我国现行的信用评价体系不能准确地评估科技型小微企业的信用状况。为解决信用评价中的不确定性和模糊性,利用直觉模糊数的多属性评价方法,构建综合信用评价指标体系;建立直觉模糊判断矩阵,利用定性与定量相结合的层次分析法确定评价指标权重,并利用改进的TOPSIS法对方案进行排序。应用实例表明,基于直觉模糊的科技型小微企业信用评价方法计算简便,评价结果精准科学,具有较好的实用价值。China＇s current credit evaluation system cannot accurately assess the credit status of SMEs.In order to solve the uncertainty and ambiguity in credit evaluation,the paper employs multi-attribute evaluation method based on intuitionistic fuzzy number to build a comprehensive credit evaluation index system,establishes valued intuitionistic fuzzy judgement matrix with a combination of both qualitative and quantitative methods to obtain subjective weight of attribute,and adopts improved TOPSIS solution for order preference.The application result shows that the calculation of multi-attribute evaluation method based on intuitionistic fuzzy number is simple,its assessment result is more accurate and scientific,and its application value is much better.
