The invention belongs to the field of wireless cooperative communication system technology, and particularly relates to a multi-user cooperative communication incentive method in a dual information asymmetric network environment. The method comprises the following steps: mapping a cooperative communication network into a labor market, and establishing a source node model and a relay node model in combination with the characteristics of a market-driven contract theory; and in consideration of the selfish nature of the relay nodes and the constraints of individual rationality, establishing a multi-user cooperative communication incentive optimization model in the dual information asymmetric network environment for the adverse selection problem caused by the private information of the relay nodes before contract signing and the moral hazard problem caused by private behaviors of the relay nodes after contract signing. Thereby, the dual objectives of achieving cooperative information screening and cooperative eff
