Abstract: Some cities in China has began to promote the system of urban appearance and environmental health responsibility area, and explored the establishment of self-regulation organization of urban appearance and environmental health responsibility area. In this paper, the self-regulatory organization and its members are taken as the two sides of the game to establish the evolutionary game model, and the incentive mechanism is introduced;then the willingness of the two sides of the game under different income is calculated, and a stability analysis is carried out. Finally, MATLAB simulation is used to analyze the influence of parameter change on the evolution result and path. The results show that the rational incentive mechanism greatly improves the enthusiasm of the organization members, and the incentive mechanism is set as positive incentive and negative incentive, among which positive incentive includes honor incentive and financial incentive. At the same time, the higher government departments should strengthen the supervision of self-regulatory organizations, vigorously publicize the self-discipline and self-governance of sanitation, improve the self-discipline and self-governance consciousness of the organization members, and make the management of self-regulatory organizations run more smoothly.
