Based on the study of scholars at home and abroad and from the point of theoretical and empirical study, this paper analyses the impact of foreign trade and FDI over China's business cycle using many econometric methods such as Unit Root Test, Co-integration Tests, Granger Test, Pulse-response Function and variance decomposition based on VAR model and draws the conclusion as follows:Firstly,there is a close relationship among foreign trade, FDI and business cycle. Foreign trade and FDI are the important transmission channel of the economic cycle. Secondly, the impact to economic fluctuation from foreign trade is greater than that of FDI. Thirdly, In the long time, there is fine interactive circulation among foreign trade, FDI and economic growth. When the short-term deviation from equilibrium happens, there is a self-balanced mechanism in the system.Fourthly,the active effect outweighs the negative effect which the foreign trade and FDI brings.
