The analysis of economic environment is the basis of well managerial decisions for enterprises. However, the relationship among economic variables in the real world is a kind of dynamic complexity problem. Economics usually take advantage of mathematics to solve this kind of problem. Therefore, it will be very difficult for business administrators to analyze the long-term dynamics competitive. This study integrated system dynamics thinking and dynamics of strategic maneuvering to build a systems feedback model of dynamic competitive environment, which can be used to analyze the long-term dynamics of competitive variables under different scenarios, including the dynamic thinking of growth and core competitive strategy. Linked with balanced scorecard interface, the model will become a decision support system of dynamic competitive analysis, which can provide business administrators with the analytic tool of dynamics competitive environment to improve their decision qualities concerning finance, production, and marketing.
