Abstract: The exchange of material, energy and information occurs in any system (ecosystem, natural system, process system, social system, market system) of the world, generating material flow, energy flow and information flow both in time and space.According to the field synergy principle, this paper describes how material flow, energy flow and information flow affect and depend on each other,and indicates that the study on the synergy among material flow,material flow and information flow could achieve harmonious interaction,so as to form an optimum ordered structure both in time and space.
