Abstract:Ensuring the long-term and sustainable operation of the symbiosis network for "urban mining" utilization is an important starting point to optimize the resource recycling efficiency and help achieve the dual carbon goals. As the endogenous driving force for the stable operation of the symbiosis network, identifying the core influencing factors of value co-creation is a necessary prerequisite. An indicator system is established with 24 indicator factors that are extracted from the four subsystems of the symbiosis network, namely "symbiotic unit", "symbiotic mode", "symbiotic interface" and "symbiotic mechanism". Based on this indicator system, a questionnaire is designed to invite experts to judge the relationship between factors as initial data. In order to analyze the interaction between factors and the contribution to the system comprehensively, a Fuzzy-DEMATEL-ANP-FCM integration model is designed to identify the core influencing factors and quantify their mechanisms scientifically. The results show that the demonstration drive of the existing symbiotic relationship, the construction of information sharing platform, the persistence of symbiotic relationship, and the degree of stakeholder collaboration are the core factors to achieve value co-creation. Among them, the driving force of the existing symbiotic relationship has the largest contribution to the system, and the policy diffusion effect of the persistence of symbiotic relationship is the strongest; In addition, factors such as the degree of complementary advantages between symbiotic parties, the intensity of industry competition, and symbiotic additional benefits play an intermediary role in realizing value co-creation.
