The paper aims to examine the relationship between changes and volatility of China's Renminbi (RMB) exchange rates and its agricultural export.
A GARCH(1, 1) model is specified to measure the exchange rate volatility and autoregressive distributed lag regression with structural break dummy variables is estimated based on the results of unit root test with structural break.
The export supply model reveals that the net trade effect of RMB exchange rate movements relies on the comparison of exchange rate level change (appreciation or depreciation) effect and exchange rate risk effect. The empirical examination results, taking China's agricultural exports to Japan as a case, show RMB depreciation against yen will promote export growth while appreciation hinder export, and exchange rate volatility positively stimulates agricultural exports to Japan. However, the effect of exchange rate volatility on the export is much smaller than that of exchange rate level, which leads to a negative net effect to the export.
The constructed model and applied methodology contribute to a better understanding of the relationship between changes and volatility of China's RMB exchange rates and its agricultural export.
