China has entered a crucial period of further growth and restructuring that will last until 2025. Based on a review of the major factors affecting China＇s potential economic growth, this paper has created an integrated economic system model consisting of system dynamics, econometrics, and input-output for the forecast of China＇s economic size and structure by 2025. Analysis shows that prior to 2025, China will be able to maintain a potential annual economic growth rate of 5.7%-7.2%. Faced with an international environment of a possible slowdown of advanced economies and diminishing demographic dividends, China needs to further expedite its urbanization process, enhance R＆D and education spending, increase total factor productivity （TFP）, vigorously develop the tertiary sector, and expand consumption in order to achieve the optimistically estimated growth of 6.6%-7.4% during the period of 2015-2025. Economic growth should be accompanied by the upgrade of industry structure and improvement of investment and consumption structures.
