A decision-making optimization method and an apparatus. The method comprises: determining a prediction result contribution of each decision feature variable in a prediction model given a user data feature (110), the prediction model being created based on a decision-making target, and the prediction model comprising a decision feature variable and a non-decision feature variable; on the basis of the determined prediction result contribution of each decision feature variable, constructing a decision feature variable combination to be optimized (120); performing optimization processing of variable values of each decision feature variable in the decision feature variable combination (130), so as to make a prediction result corresponding to the prediction model optimal; and, according to variable values of each decision feature variable after optimization processing, performing decision-making optimization processing (140). Using the present method, it is possible to realize optimization of personalized decision-making for a user.
