Urbanization is China's biggest endogenous demand and a new driving force for China's economic growth. If we grasp urbanization, we will grasp the main contradiction of China at this stage. It is an objective trend of the inevitability of China's economic and social development. If we grasp the "Outline" of urbanization, we can achieve "Outline". Therefore, if China's potential economic growth rate wants to rise to a new level in the future, it must take the new urbanization as a breakthrough point, combine the current economic development situation and the main contradictions presented by the country, and start again in the process of continuous reform to lead the sustainable and healthy development of China's economy.
