Rebate, as a significant method to enhance cooperation between retailers and suppliers, has been widely applied among different commercial agencies. In this paper, we studied the effect of rebate on the evolution of cooperation in spatial social dilemmas. With a rebate mechanism, cooperators will share a part of payoff to cooperative neighbors. Simulation results shows that the rebate mechanism can promote cooperation significantly. When rebate mechanism works, the low-payoff boundary cooperators could receive extra rebates from the high-payoff cooperators in cooperator cluster. This helps cooperators defend the invasion of defectors. As a result, cooperators could survive and even dominate the system. The research can provide a new insight to explore the widespread cooperative behavior in the natural world.
