Eco‐industrial parks (EIPs) is a complex system, composed of a variety of companies with embedded ties. Members in EIPs shape the “Eco‐Industrial Chain Network,” the industrial coupling symbiosis network (ICSN) system, in which businesses cooperate with each other and share the mutual benefits at the same time. In order to study the development levels of the ICSN system in EIPs, this paper uses the grey relational analysis (GRA) method to evaluate the eco‐efficiency of coupling and symbiosis network in EIPs in oil and gas resource‐based cities. The results show that the overall level of eco‐efficiency and the stability of ICSN could be reflected through the application of the economic, environmental, and the dematerialized cycle and network structure relational analysis. Furthermore, it confirms the feasibility and applicability of the evaluation model and the evaluation indicator system.
