英文摘要：

In the past few years, a growing number of eco-industrial parks （EIPs） which are constituted by symbiotic industrial clusters are planned and developed in the industries agglomerated areas in China. It is one of the most important local actions for exploring the practice of circular economy. Based on the theories of circular economy and industrial ecology, the paper provides a framework of EIP development integrating the existing planning of EIPs. There are five key dimensions summarized in this conceptual model： symbiotic industrial network construction, creation. Chemical spatial planning, environmental management, integrated infrastructure design, and cultural identity Furthermore, the development framework was devised and applied in the case study analysis of Ningbo Industry Zone. Some strategies and suggests for the EIP development are provided.
