Prediction Analysis of USD-CNY Trend Based on BP Neural Network

摘要

Exchange rate plays a vital role in the healthy development of a country’s economy. The back propagation (BP) neural network is used to predict the trend of the exchange rate of US dollar to China Yuan (USD-CNY) in this paper. And the result indicates that USD-CNY shows a trend of decline in recent years. Through constructing the relational expressions and the analysis of the factor affecting USD-CNY we find that the balance of payments, commodity prices and USD-CNY has a negative correlation; the rate of inflation, gross domestic product (GDP), foreign exchange reserves and USD-CNY has a positive correlation.
