The appreciation of RMB had influenced China’s export significantly in a number of dimension, the previous literatures focused on the influence of total amount of exports and the export structure of different commodities but ignored analyzing the influence of RMB appreciation on private sector export proportion and processing trade export proportion from the view point of trade structure. Using monthly data between 2005 and 2008, our VAR model analysis found that RMB appreciation would reduce the private sector export proportion in the short term, but would be able to improve the private sector export proportion in the long term; and in the same time, RMB appreciation would increase the processing trade export proportion in the short term but in the long term would reduce the processing trade export proportion.
