Can GDP really express a country's economic strength? How is it calculated? Who will do the math?

GDP does not really express a country's economic strength. Calculation formula: GDP = consumption+investment+government expenditure+export-import (meaning the total consumption of ordinary people+money deposited in the bank+government expenditure+total value of exports abroad-total value of goods imported from abroad)-is this easy to understand? This is what accounting says, and the popular point is accounting. A few years ago, there was a popular joke: two people were walking in the street. A saw a pile of shit on the ground and said to B, "I'll pay 5 million." Do you dare to eat? " B thought it was a good deal, so he ate that pile of shit. As they walked on, B also found a pile of shit, so he did the same. A also thought it was a good deal and ate the shit happily. Before long, A had some questions and asked B, "Don't you think we both ate a pile of shit for nothing?" Who knows that B calmly replied: "No! The two of us have created an output value of 6.5438+million! "

This is a rude joke, but it is thought-provoking. Xiao Zhao, an economist, once mentioned three hazards of the "GDP-only theory" in an article. The first hazard is that he didn't realize that the growth of GDP will not only bring about the growth of social wealth, but also bring about the decrease of social wealth in some cases. The second harm lies in ignoring the law and often sacrificing long-term interests for short-term goals, which affects the sustainable development of the economy. The third harm is that in the process of pursuing total growth, people often ignore the balance of structure.
