Abstract: Enterprise participation is very important for the success of public goods technological innovation. In the contract design, traditional factors cannot be ignored, and internal characteristics of agents and external environment also need to be considered. A dual agent model based on fairness was constructed to study the influence of subcontractors’ fairness on optimal contract and expected revenue of the public sector. The results show that the greater the difference in the strength of fairness preference between the two subcontractors, the more favorable it is to improve the expected utility of the public sector. However, two prerequisites must be met. First, the subcontractor with a higher level of ability has a stronger strength of fairness. Second, the public sector must redesign the size and combination of incentive coefficients based on fairness and random dependence so that subcontractor with stronger fairness and higher levels of ability has incentive advantages.
