英文摘要：

In this article Webster- Wind model is modified based on Chinese management context, and the decision - making model of Chinese enterprises has been built. This modification model has been tested by the questionnaire survey, which shows that expert power, information power and legitimate power have significantly positive effects on buying decision orientation, and to be specific, the first is stronger than the second, and the second is stronger than the third. Moreover, both information power and internal familiarity have significant effects on expert power, but neither on legitimate power. However, expert power has a significant effect on legitimate power, and at the same time, information power is positively affected by internal familiarity.
