Study on the formation mechanism of ecological relationship in an Eco-production network based on the node correlation

Basing on the theory of complex network and the properties of Eco-industrial system(EIS), this article supply the heterogeneous growth model for EIS, and make a theoretical study on essential attribute of complex network, such as degree distribution, convergence factor and average path length. Different factors are discussed under the influence of EIS, a complex network in-degree and out-degree distribution of basic rules, in order to explore the growth mechanism of EIS, and provide a theoretical basis.
