To investigate the incentive mechanisms of cooperation, we propose an other-regarding preference based reciprocal rewarding mechanism by incorporating the dynamic adjustment of link weight into the spatial prisoner's dilemma game. Under the influence of other-regarding preference, players are willing to sacrifice personal payoff to reward the cooperative neighbor who has the greatest link weight. The reciprocal reward is dynamically adjusted according to the adaptive adjustment of link weight and the intensity of other-regarding preference. Extensive simulations reveal that the proposed rewarding mechanism significantly promotes the evolution of cooperation. Both the dynamic adjustment of link weight and the other-regarding preference impact factor play an essential role in the emergence of cooperative behavior. To further validate the above outcome, the evolution of cooperators' density and the alteration of average payoff and fitness are explored in a microscopic perspective.

为了研究合作的激励机制，我们通过将链接权重的动态调整纳入空间囚徒困境博弈中，提出了一种基于偏好的互惠机制。在其他偏好的影响下，玩家愿意牺牲个人收益来奖励链接权重最大的合作伙伴。根据链接权重和其他优先级的强度的自适应调整来动态调整互惠奖励。大量的模拟表明，提出的奖励机制极大地促进了合作的发展。链接权重的动态调整和其他相关的偏好影响因素在合作行为的出现中都起着至关重要的作用。
