It has described the evolution and drawback of the system structure of the modern traditional accounting information system sequentially, construction principle and the design based on the Event Approach's accounting information system and foundation of realizing of the new-type accounting information system; It has proved social economy and market competition are the most primitive demand. It has promoted the change of the management theory. Management theory and accounting theory have offered the mode of constructing for accounting information system; The influence of the information technology of the network is the most basic.
