}Exchange rate refers to the ratio or price comparison between one country's currency and another country's currency, or the price of another country's currency expressed in one country's currency. Exchange rate changes have a direct regulatory effect on a country's import and export trade. Under certain conditions, external devaluation of the domestic currency, that is, an increase in the exchange rate, will play the role of promoting exports and restricting imports; conversely, external appreciation of the domestic currency, that is, a decrease in the exchange rate, will play the role of restricting exports and increasing imports.
