Research findings show that the four kinds of heterogeneous positive shocks can promote the rise of China's output and inflation, and that the output effect is greater than the price effect. World output and trade shocks only exert short-term effects, world technology shocks exert long-term effects, and exchange rate shocks produce positive effects in a short term but negative effects in the long term. By adopting Taylor’s rule including the exchange rate factors, counter-cyclical regulating effect of monetary policy can be fulfilled. In this regard, we should attach importance to and treat rationally the impact of the world economic shocks on China's economy, hence enhancing the pertinence and foresight of regulating policy
