Abstract “Zero‐Waste industrial park” is critical components supporting the construction of “Zero‐Waste city”. However, there remains a deficiency in methodology regarding how to scientifically assess the “zero‐waste” level of industrial parks. Methodologically, material flow analysis (MFA) reveals the input, output and flow of materials within a system, and quantifies the environmental load imposed by material flows on the system. Energy flow, based on the law of conservation of energy as its fundamental principle, tracks the pathways and processes of energy flow within the system, and uncovers the flow characteristics and conversion efficiency of energy inside the system. In this study, the comprehensive evaluation indicators system for “zero‐waste park” is established based on the circular economy theory, the structural characteristics of material and energy metabolism of the park and the entropy method. The results show the park is currently dominated by traditional manufacturing enterprises, such as organic chemical raw materials, which results in the high intensity of solid waste emission. The energy output rate is 7.41 × 10 4 yuan·t −1 , and the resource output rate is 3.135 × 10 5 yuan·t −1 . The utilization rate of solid waste only reached 37.49%, which results from the content of useful components, separation technologies, and economic benefits. The research results have fully leveraged the guiding roles of the “zero‐waste industrial park” indicator system and environmental performance evaluation system. They enable scientific assessment of the construction level of “zero‐waste park” and help identify the strengths and weaknesses affecting the effectiveness of “zero‐waste park” construction, thus optimizing the construction tasks of “zero‐waste park”.
