麦当劳遍布全球五大洲119个国家，拥有约32,000间分店，其在各个国家中均推出符合当地特色的美食，但是巨无霸汉堡总是出现在每一家麦当劳的菜单中。从1986年开始，《经济学人》杂志每一年都会推出一个巨无霸指数，其目的是以一个巨无霸汉堡的价格来观察国家和国家之间的货币汇率是否合理。在一带一路的大背景下，中国与参与一带一路的国家贸易联系愈发紧密，人民币在相关国家的地位也逐步上升，在巨无霸指数下应能体现。本文引入2000-2020年的原始巨无霸指数与经GDP调整过的巨无霸指数，比较在美元和人民币作为基础货币下，一带一路国与非一带一路国实质汇率的差异。

McDonald's owns 32,000 restaurants in 119 countries on five continents, serving local fare in each, but the Big Mac burger is always on the menu at every McDonald's. The Economist has been running a Big Mac Index (BMI) every year since 1986. Its aim is to observe if the currency exchange rate between countries is reasonable at the price of a Big Mac burger. Under the background of The Belt and Road, China's trade relationship with countries participating in The Belt and Road is getting closer, and the status of RMB in relevant countries is also gradually rising. Can it be reflected in the BMI? This study introduces the original BMI and the GDP adjusted BMI from 2000 to 2020 to compare the real exchange rate differences between The Belt and Road countries and non-The Belt and Road countries when Dollar-based and RMB-based currencies are used.
