This paper is based on "Trilemma" which is induced from MF model. In order to overcome MF models inherent defects, this paper constructs a static model headed by government on choice of optimum exchange rate regime. Through the analysis of the model we can see that the choice of exchange rate regime is a dynamic process should be decided in real situation. No single exchange rate regime is right for all countries or at all time. Under certain condition intermediate regime may be the optimum one, but the possibility will decrease with the increase of international capital flow.

本文从蒙代尔——弗莱明模型精炼出的"三元悖论"出发，为了克服其内在的缺陷，构建了一个政府主导的静态最优汇率制度选择模型，模型分析表明：汇率制度选择是一个动态的相机决策过程，没有哪一种汇率制度对所有国家或某一国的所有时期都适合；在一定条件下，中间汇率制度可能是最优汇率制度，但是其可选择的区间随着资本流动程度的加大而缩小，最终最优汇率制度将内生的向两极分化。
