Abstract: In order to better forecast the impact of the various elements of demand on economic growth in China,we have used bounds testing to carry out empirical studies based on the unrestricted error-correction model,the results verify that there is a long-run equilibrium relationship between the demand for economic growth and its determinants,and the different components of economic demand have different impacts on the economic growth in China.In the long run,only gross capital formation has a positive effect on the economic growth,in the short run,each element of demand is found to be significant.
