Abstract: This paper analyzes the effect of platform service quality on platform competition result from three aspects: platform' s basic service, platform's value-added service and complementors' service. By constructing the utility models of bilateral user and the profit function of the platform, the influence of the change of the plat-form service quality on the scales of bilateral user and the platform profit is studied, and then the numerical simu-lation is carried out by using MATLAB. The results show that: First, the improvement of platform basic services, platform value-added services and complementors's ervices will all lead to the increase of bilateral user scale and platform profit, but the improvement of complementors' service quality will do the best; Second, the industry characteristics of a platform will influence its investment in the service quality; Third, the platform which provides a small amount of basic services should focus on improving the quality of complementors service.
