In the process of urban transformation dominated by stock development, the traditional project cost management model based on new projects is difficult to adapt to the characteristics of urban renewal, such as fuzzy boundaries, diverse subjects and complex cost structure. The purpose of this article is to build an innovative model of cost management that integrates the whole life cycle perspective and dynamic control ability, and respond to the governance needs in the renewal practice through the dual path of institutional coordination and technical empowerment. The research adopts the method of theoretical construction, systematically analyzes the new requirements of urban renewal for cost management, and then designs a management framework covering the whole process of planning, design, implementation and operation and maintenance, and deeply discusses the institutional interface and technical carrier supporting the implementation of this framework. Only by changing the cost management from a static accounting tool to a value coordination mechanism and embedding an elastic contract arrangement and a multi-source data fusion platform can we effectively balance public interests, market efficiency and financial sustainability. This model reconstructs the logic of the generation and circulation of cost information, and also provides structural support for the risk sharing and consensus reaching of urban renewal projects.
