As a regional industrial ecosystem characteristics and build ways, Regional Industrial Symbiosis Network becomes a hot research topic recent years. However, the regional industrial symbiosis network is still in the theoretical study and practical exploration stage, and roughly formed research directions, such as the formative causation of regional industrial symbiosis network, the complexity metrics of regional industrial symbiosis, the flexibility and stability of eco-industrial network, the evolution of regional industrial symbiosis system, the study based on social network system, the eco-industrial park construction. These studies can provide important theoretical support and implementation basis for the development of China's circular economy, as well as the eco-industrial park construction.
