Abstract: According to the characteristics of the Special Fund for Financial Support to Agriculture, a performance evaluation system is proposed for the fund, with some factors taken as evaluating indices, including social efficiency, ecological benefits, economic efficiency, project initiating, implementation, approval and management, funds collection, financial regulations and financial supervision level. A primary model is developed for the evaluation using fuzzy theory and analytic hierarchy process. The model objectively reflects the performance rating of the special fund. The performance of each special fund for agriculture can be ranked according to the monodromies, calculated by the model, of the fuzzy comprehensive evaluation results. Furthermore, the model can be used to calculate the membership contrast coefficients of the fuzzy comprehensive evaluation results so as to obtain the internal structure information of the membership of various ratings.
