The Nineteenth congress explicitly put forward the notion that “economic growth mainly relies on the coordination between consumption, investment and exports” and sets the goal that consumption, investment and exports will be coordinated to boost economic development. In the start of the 13th FiveYear Plan, we based on a system coordination model,extensively establish a demand coordination rate model and measure the that 2000—2017 average demand coordination rate is 0.647 9, as well as using empirical data and the Almon polynomial distribution lag model to investigate the relationship between the demand coordination rate and economic growth. The empirical results show that the demand coordination rate has a positive effect on economic growth, but the immediate impact is not significant, while the lag effect is obvious, the time limit is three years and the strength is decreasing.In addition, in the long run, the demand coordination rate also has a significant positive effect on economic growth. Therefore, during the period of the new normal, our country should still adhere to the “consumption, investment and exports coordinately developed to heave economy growth” policies and regulations, appropriately finetuning the income distribution, social security and other related policies, promote the economic growth mode transformation and ultimately achieve sustained, stable and highspeed growth.
