Abstract: The influence of horizontal fairness concerns among respondents on the knowledge sharing incentive in crowdsourcing the contest innovation project was studied. A model with and without knowledge sharing incentive (called KS and NKS respectively) was established and solved based on the construction of the utility function of the respondents under fairness concern. Then, the impact of fairness concerns sensitivity on optimal knowledge sharing incentive degree, optimal private solution effort, knowledge sharing effort, crowdsourcing project performance and expect economic benefits of both sides was studied by means of theoretical analysis and numerical simulation, and a comparison was made with the non-knowledge sharing incentive. The result shows that fairness concerns can reduce the threshold of knowledge sharing incentive mechanism, and enhance the optimal knowledge sharing incentive degree of the crowdsourcer. The knowledge sharing effort is positively related to fairness concerns, but the private solution effort is negatively related to it. The relationship among crowdsourcing project performances, the absolute economic benefits of the crowdsourcer and fairness concerns depends on the ratio between the private effort performance transformation rate and the knowledge sharing effort performance transformation rate. It also finds that the incentive mechanism of knowledge sharing can achieve a win-win result of economic benefits of both parties, while its economic value increases with the sensitivity of fairness concerns, and is regulated by the number of participants.
