With the further expansion of business model, the traditional e-commerce platform can not meet the requirements of the development. Comparing with its own non-flexibility, non-mobility, non-compatibility and non-intelligence, this paper distributed intelligent agent based on the framework for e-commerce platform. According to the functional requirements of e-commerce system, we can identify the agent role in the system, such as customer agents, business agents, business centre agents and payment agents. The roles of these agents are intelligent, active, distributive and collaborative; they are also through the framework of multi-agent communication mechanism and intelligent decision-making mechanism for better coordination. Therefore, they are providing better information dissemination and transactions for the business; and also providing the real-time and flexible service for the costumers.
