Based on the value flow process, this paper constructs a value flow GERT network model, proposes confirming methods of relative parameters, and studies the analytical solution of the value flow GERT network model. Then the paper applies value flow GERT network model on the field of macroeconomics through an example of value flow processes between sectors of the economy system, gets outputs, transfers probability, value increment quantities and values of variance by inputting on different sectors of the economy system, which fully reflects the processes of dynamic input-output and the value increment through value flows. It will provide effective quantitative supports for the country's macro-control.
