How to achieve diversified and cooperative management of construction and demolition waste (C&DW) has always been a difficult problem for the government and the public. To achieve collaborative governance, it is necessary to coordinate the conflicting interests among multiple subjects and reasonably determine the collaborative goals. This study aims to illustrate the necessity and feasibility of collaborative governance, determine the phased resource utilization rate target from the perspective of balance of interests, and design a dynamic adjustment mechanism for local government’s collaborative governance target, regional C&DW resource utilization rate and rewards and punishments from a quantitative perspective. From the perspective of maximizing social benefits and balancing the interests shared by three stakeholders: construction and demolition enterprises, waste resource treatment enterprises and the government, the system dynamics (SD) and multi-objective planning (MOP) coupling model (SD-MOP) are constructed. The MOP model is used to solve the optimal solution that satisfactory to all parties, and the SD model simulates the internal and external environmental changes of the C&DW management system under the optimal solution to provide dynamic parameters for the MOP model. This paper takes Jiangbei New Area in Nanjing, China as an example to verify the validity of the proposed SD-MOP model. The calculation results show that the three stakeholders with relevant interests can achieve a win-win situation by integrating resources and optimizing resource allocation, while promoting the goal of collaborative governance, that is, improving the utilization rate of C&DW resource utilization. In addition, the model also gives the specific time for the establishment and realization of the phased target of resource utilization in Nanjing Jiangbei New Area, with resource utilization rate targets of 75%, 79% and 84% in 2024, 2029 and 2036, respectively.
