What is a gdp bubble?

The so-called economic bubble, seemingly prosperous, is actually an illusion.

Although I have no financial talent at all, since I saw the news about GDP on TV very early, I have been thinking, how can China's GDP keep growing at 8- 1 1% every year? Is there a frightening bubble hidden behind this seemingly glamorous data, or is it deliberately pursued by the government every year?

I just read something, and I seem to have a superficial understanding in my extremely underdeveloped brain ~

A large part of China's GDP is made of steel. The government spent a lot of money that should have been invested in private enterprises to invest in the steel industry. In order to ensure a bumper harvest, the seemingly attractive appearance of prosperity was vulnerable in this financial tsunami.

China's GDP also has such a way of generating income: the house is built, which is very good. When it is built, everyone is laid off; What shall we do? Rebuild the second building. It's over. No more people can be laid off. If the first building is found useless, it should be demolished. (The income from demolition is also included in GDP. So in the process of demolition and construction again and again, we go back and forth, wasting money and harvesting GDP.

Seeing a joke made by a netizen, I think it's really ironic, so I'll show it to you by CTRL C V ~

Two economists (brothers and sisters) were walking in the park, talking while walking ... when they suddenly found a piece of shit on the road. The elder brother said to the younger brother, I'll give you 50 million if you eat shit. The younger brother calculated that it is quite cost-effective to eat 50 million yuan for a lump of shit. So the deal was reached, and the senior gave his brother a check for 50 million. Keep walking and find another lump. The younger brother smacked his lips, thinking that the smell of shit was really unpleasant, he said to his younger brother, I'll give you 50 million if you dare to eat it. The big brother is distressed by his 50 million. Seeing his brother say this, he ate clean for a while. So the weight of 50 million returned to my brother's wallet. Go on, brothers and sisters hugged each other and cried: I didn't earn a penny, but I ate a lump by myself ... When I returned to the master, the old professor was so excited that he trembled all over: 100 million.
