[Purpose/significance]By constructing the value flow GERT network model of the business network information ecological chain,the paper describes the value flow process among various information subject in the business network information ecological chain,and reveals its internal mechanism of value flow and value-added process,in order to provide the theory and method for the study of the value flow of the business network information ecological chain.[Method/process]Firstly,the GERT network model of value flow in business network information ecological chain is constructed and the transfer parameters of multi-value flow are determined.Then,the main parameters,functional relationships of GERT network model of value flow are analyzed.Finally,the cooperative organization and management mechanism of GERT network of value flow is analyzed.[Result/conclusion] In the value flow GERT network of the business network information ecological chain,each information subject realizes the value of each information subject through the flow of information,capital,material and other value carriers in order to realize their respective value and the common goal of maximizing the value of the system as a whole,and achieves value increment by using cooperative organization mechanism.
