| Abstract: | Purpose/significance] This paper analyses the changes of evolution process of network information ecological chain with the complex network theory, to promote it transform from disorder, low efficiency and unstable state to orderly, efficient and stable state, and to provide the reference for the simulation and empirical analysis of network information ecological chain.Method/process] Based on the complex network theory, it analyses the dissemination characteristics and structural changes of information node, proposes the dynamic evolution model of network information ecological chain, and calculates the velocity equation and velocity curve. Then using the logistic equation theory of the life cycle curve, it describes the evolution curve of network information ecological chain.Result/conclusion] According to the evolution velocity and changing acceleration of curve, it finds that the evolution process of network information ecological chain can be divided into four stages, namely the embryonic, growth, stable and involution period, which culminate the effective mode of "clustering-collaborative-cycle", to help establish a scientific and effective development mechanism of network information ecological chain. |
