Abstract: The analysis shows that previous discussions on reputation collaborative incentives often lead to the failure of incentives, with the following manifestations: A reputation incentive model that only considers one factor will lead to incentive imbalance, The cooperative incentive model without reputation is easy to make the incentive surplus. Therefore, the substitutability between construction period and quality factors are fully considered. From the perspective of the owner, a two-stage dynamic incentive model considering both explicit reputation and implicit reputation is constructed to solve the above problems. Furthermore, the method to determine the effective interval of the multi-factor collaborative incentive model with dual reputation is studied. Finally, the rationality of the model is verified by an example and data simulation.
