Based on the information sharing issues in construction of large-scale hydropower projects, they are investigated from the point of suppliers and general contractor. An evolutionary game model for the information sharing between the suppliers and the contractor is established, and numerical simulations are carried out. The Matlab simulations show that when all the subjects in this game choose to share their information, the simulated results vary according to the shared quantity of information, information earning coefficient, hitchhiking earning coefficient and information sharing cost coefficient. Under this condition, the owner's company can make more game subjects turn to share their information through reward and punishment. In this way, the engineering construction efficiency can be raised, that is, time will be shortened, and the cost can be reduced.
