ABSTRACT: This paper analyzes the monthly average USD/CNY exchange rate data from June 2006 to June 2025 using time series methods, with a total of 229 samples. The EViews software is employed to construct an ARIMA model for this time series. The model accuracy is tested using data from July 2023 to June 2025, and the USD/CNY exchange rate is forecasted for the next two years.
