Abstract: By exploring the links between balanced scorecard principle and knowledge alliance， a validity evaluation index system of incentive synergy was established on the basis of the balanced scorecard principle. According to the relevant index system， a fuzzy comprehensive evaluation model was built to evaluate the validity of incentive synergy. The data from a knowledge alliance that composed of a college and a software development enterprise in Liaoning Province were obtained by questionnaire survey， and the weight of each index was determined by analytic hierarchy process. Finally， the effectiveness of incentive synergy was evaluated with the established fuzzy comprehensive evaluation model.

Key words: knowledge alliance, effectiveness of incentive synergy, balanced scorecard, AHP(analytic hierarchy process), fuzzy comprehensive evaluation
