摘　　要：由于P2P网络节点的匿名性和贡献资源的自愿性,绝大多数节点缺乏提供服务的积极性,从而引发了P2P网络中的"Free riding"问题。在分析"Free riding"问题的基础上,依据拉弗曲线和美国个税方案,提出了一种基于个人所得税的激励机制(PIIM)。基于"富人多交税,穷人少交税"的思想来实现收入的二次分配,进而实现P2P系统的节点公平性。基于校园网运用的实验表明,该激励机制促进了社会公平,达到了激励节点参与资源共享的目的。Due to the anonymous participation and voluntary resource contributions in P2P system,the majority of peers lack eagerness to contribute resources or provide service to communities,which leads to the prevalence of＂free riding＂.Based on the analysis of＂free riding＂,according to Laffer Curve and U.S. Personal Income Tax,this paper gives a new incentive mechamsm＂PIIM＂from the personal income tax idea.Based on the idea that＂Tax the rich more than the poor＂,a second distribution of income is achieved, to be fair in P2P system.The use of campus network based on the experiments show that the incentive mechanism promotes social equality,and the goal that the node can participate in resources sharing is fulfilled.
