For urban renewal, there are a lot of benefit-related subjects and their needs are cumbersome. As a result, the functions and mode of the platform are relatively complicated. In order to build a platform to solve the problem of public service missing in urban renewal, a study about the needs of the subjects and the function requirements of the platform has first been done. According to this study, we proposed the architecture and mode of urban renewal public service platform, and carried out a detailed analysis of its internal structure, service mode and guarantee system. The platform is finally designed as an open and service-oriented distributed system. Through this way, the design is consistent with the actual operation of urban renewal and can be used to build the platform.
