System Identification of Regional Circular Economy Based on Group Method of Data Handing

In this paper, based on the China´s Circular Economy development indicators, with Group Method of Data Handing, the cycle of the network structure of China´s regional Circular Economy is recognized in the following aspects: the economic development of Circular Economy, social development of Circular Economy and ¿3R¿ Principle of Circular Economy. On the basis of the cause-effect chart that regional Circular Economy system in China is produced by the system of linear equations fitted, the paper provides the general regional Circular Economy network structure and preliminarily defines the system attributes of regional Circular Economy development evaluation system. Two results are obtained in this paper, one is that there are a small amount of isolated indices in regional Circular Economy network and another is that the development law represented by the node-degree attributes of static network structure of Circular Economy is linear increasing. Finally, some China´s Circular Economy development strategies are given from the angle of China´s Circular Economy development internal structure.
