Study on the impact of RMB exchange rate fluctuation on China coal import trade

This paper uses monthly data from January 2010 to March 2015 as the research object, on the basis of the ADF unit root test, the autocorrelation test and the cointegration test, uses the generalized difference method to establish the long-term stable equilibrium relationship of the variables1. The error correction model of the short-term equilibrium relationship between the variables is established. Analyses whether the change of nominal exchange rate of RMB will affect China's coal importsand how toinfluence. Example analysis shows that the appreciation of the RMB will lead to increased imports of China's coal. The rise ofChina's coal price index will enable China to import more coal. On behalf of China's economic development level of China's Manufacturing Purchasing Managers Index will also affect China's coal imports, but the impact is not significant.
