We usually use two indicators to describe the operating system of the whole society, one is called industry classification, and the other is called occupational classification.
The division of labor between occupations and industries is an important indicator of the level of social development. Generally speaking, the more detailed the division of labor, the higher the level of socio-economic development.
For example, it is often said that if young and old people do not have children, obstetricians and gynecologists will be unemployed. Here is one of the descriptions of the profession of an obstetrician and gynecologist.
Regarding the description of the profession, we have already covered it in the previous article. The data shows that doctors in obstetrics and gynecology are only a very small link in the huge occupational classification, and even if many people are unemployed, this profession will not have a significant impact on social and economic development.
Obstetrics and gynecology, on the other hand, belong to the industry classification system.
According to the definition of the national standard "Industrial Classification of the National Economy (GB T 4754-2017)", obstetrics and gynecology belongs to the fifth level of the national economic industrial classification, and its first four levels are: health society - health - hospitals - specialized hospitals - obstetrics and gynecology (department) hospital services, or belong to the fourth level, respectively: health society - health - professional public health services - maternal and child health care hospitals.
Based on this method, there are 1,382 sub-categories in the country in the same industry as the maternal and child health hospitals.
If we put all the industries into a chart, the maternal and child health hospital is one of the tiniest squares, as shown in the figure below.
1 in 1382, the influence of any industry on the national economy is not as great as everyone thinks. However, there are some industries that occupy a relatively important position in the national economy because of the large number of employees or the large proportion of the national economy.
For example, the real estate industry is actually composed of three different industries, including: construction, finance and real estate. The construction industry is engaged in building construction, the financial industry provides the funds needed for construction, and the real estate industry provides services such as development and operation, property services and leasing for buildings.
However, the real estate industry as understood by everyone is far beyond the above definition: people buy a house, and its main purpose is to live, which not only needs someone to build, raise funds and build a house with an intermediary with the buyer, but also needs raw materials, mechanical tools, furniture, household appliances, etc. to build a house.
Theoretically speaking, when you want to buy a house, it means that all the companies of the Fortune 500 are involved in the manufacturing and service process of the house in an indirect or direct way.
Therefore, the industry that most of us understand is actually far more than the officially defined industry. The degree of impact of real estate on the national economy is more appropriate to describe as "a whale falls and everything is born".
When people buy a house, it is equivalent to a whale landing on the seabed, and all walks of life in the national economy are involved in the decomposition process of this whale to a certain extent.
This is the deeper impact of real estate on the economy, and its influence far exceeds the influence of selling land to the local **.
