Extended data:

The upgrading of residents' consumption structure has the greatest relationship with income growth. With the improvement of income level, consumption follows the path of "food, clothing, housing, entertainment".

The proportion of non-durable consumer goods such as food and clothing will gradually decrease, while the proportion of durable consumer goods related to housing and transportation such as automobiles and household appliances will gradually increase. When the per capita income level reaches the level of more developed countries, the growth of durable goods consumption is limited or even may decline, and the proportion of life service expenditure such as medical care and entertainment will usher in an explosion.

The new urbanization will change the traditional economic model driven by investment in the past. It is not the urbanization of land, and the peak period of transportation infrastructure such as railways and highways has passed, but the demand for productive services such as environmental protection and information related to beautiful homeland and smart cities is more.
