【Abstract】 Through the cointegration analysis,this paper examines equilibrium relationship between China’s import and export according to the relevant data from January 1998 to July 2005 and sets up the error correction model(ECM).The Granger causes of the export and the import are found as each other in the ECM.The empirical result shows that the flexibility between import and export was increased and the trade mechanism was changed after China has joined WTO.更多还原
