Abstract: The demographic dividend is disappearing, the marginal return of capital is declining and the technical catchup space brought about by the opening to the outside world is narrowing, which lead to a continued decline in Chinas potential output growth rate China needs to shift from imitation to independent innovation stage to upgrade the potential growth rate The important force to promote the conversion of new and old economic momentum is a new round of structural reforms, especially the supply side structural reforms This reform needs to adjust the relationship between the market and the government again, and transforms the technical imitationdriven model to the innovationbased economic governance model.

Key words: new economic momentum , potential economic growth rate , technological progress
