Looking ahead to 2021，China’s global economic growth is projected to be 9%，averaging 5.5% for two years，and the economy will return to its potential growth rate. However，due to the impact of the epidemic，the global economy has contracted，the supply chain has been adjusted，and the global economy has been rebalanced.

Only based on the new development stage and the goal of “Double Cycle” under the macro resource allocation system reconstruction and reform of the original system，that will promote the success of China’s strategic transformation from the mechanism level.
