国际货币的起源和演化:基于多种群不对称博弈的演化分析

An Analysis of the Origin and Evolution of International Currencies Based on Duo-Population Asymmetric Evolutionary Game Analysis

文章建立了一个基于多种群不对称博弈的演化模型,从微观企业对国际货币的选择角度解释国际货币的形成与演化机制。在合理的初始参数假定下,我们求解了两类企业采用某种国际货币交易的临界条件。根据该模型,文章认为一种货币国际化成败的关键因素是企业使用它进行交易的意愿。文章模型可以模拟当前国际货币体系的基本特征,并可能在多个方向进一步拓展。

This article develops a duo-population asymmetric evolutionary game model to explain the formation mechanism of international currency from the decision procession of firms. By this model,the key of a currency's internationalization depends on the will of firms to use it in their international transactions. This model can simulate the main characters of current international currency system,and can be extended in many directions.
