In order to explore the factors influencing managers' decision-making ability and the relationship among them, this study puts forward the hypothesis on the basis of analysing the factors influencing the decision-making ability, constructs a neurocognitive model of the factors influencing the decision-making ability, analyses and verifies the hypothesis with the neurocognitive model in combination with the questionnaires, and calculates the path coefficient through the model. The empirical results show that decision-making information, leadership authority and corporate culture have significant influence on the decision-making ability, in which leadership authority is the main factor, and governance structure and decision-making system indirectly influence the decision-making ability through other intermediaries.
