The local construction of social credibility system is an important mission in the “13th five plan”, in which the performance evaluation and its improvement measures are highly concerted by the society. In this proposal, the provinces and important area in the Yangtze River delta region are selected to appraise their constructive performances of social credibility system with multi-stage decision-making method.

Specifically, a survey to the current constructive situation of Yangtze River delta region is conducted following the cluster results according to area similarity. Additionally, the multi-source survey information is classified and refined according to the evaluation indexes. Moreover, the transferring rule and merge mechanism is developed to aggregate the annual constructive performances of the above areas. Furthermore, according to the decision-making situation with diffident expert groups in diffident stages, the case-based reasoning technology and psychological measurement are utilized to confirm and revise the personal appraisal information, which is a useful development to the multi-stage decision-making theory. Besides, the improvement measures of social credibility system in the Yangtze River delta region are studied, referring to the appraisal results and international analogical analysis.
