采纳CBDC的博弈论分析

A Game Theory Analysis of the Adoption of CBDC

作为一种重要的区块链应用,央行数字货币(Central Bank Digital Currency,CBDC)因其能够重构金融市场、影响国家货币政策、引入新的监管政策和机制而受到世界各国的广泛关注。运用博弈论方法研究不同国家间CBDC或合成CBDC之间的竞争,可以提出两个博弈模型,通过纳什均衡分析是否采用CBDC方案。这两个博弈模型得出的结论是,无论其他国家的选择如何,每个国家都应采用CBDC项目。

As an important blockchain application,Central Bank Digital Currency(CBDC)has received widespread attention around the globe for its ability to restructure financial markets,influence national monetary policies,and introduce new regulatory policies and mechanisms.Through a game theory approach to study the competition between CBDCs of various countries or between simulated CBDCs,this paper proposed two game models to analyze whether it is appropriate to adopt the CBDC option through Nash equilibrium.The result of the two game models shows that any country should adopt its CBDC program regardless of the choice of any other countries.
