In order to improve the accuracy of evaluation model of social security system, a new evaluation model of social security system based on fuzzy comprehensive evaluation method was established in this papers. In this model, after comparison among the various factors, comparison matrix was established determining the weight of each index by Analytic Hierarchy Process (AHP). Through specific fuzzy operator, the Four of Appraisal Indexes of the evaluation system including economic factors, social factors, ethical considerations, and political factors were quantitatively analyzed. The results showed that, in a better grade, the current social security system and economic factors are the most significant factors. In addition, the model for the establishment of the socialist market economy provided a theoretical guidance and research ideas for sustainable social security system.
