A fuzzy multi-criteria decision making method based on intuition trapezoidal fuzzy number and Choquet integral is proposed and the method is further used to the evaluation of venture investment projects. Intuition trapezoidal fuzzy number is introduced to present the expert preference information, Choquet integral is used to integrate the decision matrixes from different experts, and the fuzzy TOPSIS method is applied to construct the decision model; as a result, fuzzy criteria value and ideal solution value are obtained. And then, the distance formula of fuzzy number is used to evaluate the different values between these criteria solutions and ideal solutions, resulted in the pro and con rank of different programs. In the empirical study, taking five venture investment enterprises in the high-level technology development zone as the research subject, the expert evaluation results involving their technical level, market size, product innovation, industry environmental, and government support degree are integrated with intuition trapezoidal fuzzy number. Accordingly, the comprehensive rank based on these five aspects is obtained. With such empirical study, the practicality and feasibility of the built model is further confirmed.
