Here is a brief introduction for everyone. I also study this aspect: the meaning of GDP is the sum of the final market value of goods and services produced by a country or region throughout the year. This is the theory of western economics. In fact, the value here is not exactly the same as the axiology of Marxist political economy. It should be regarded as a price and more reasonable. Generally speaking, the more things we produce (including goods and services), the more things we can enjoy, the more profits we generate, the more taxes the country gets, the more power the country has to build better infrastructure for us, invest more resources to promote economic and technological development, and the higher our international status, the more convenient it is for us to travel, live and study abroad.
I also suggest that you don't simply study China's GDP per capita and the upward trend. In fact, we have written more than 30 pages, 18000 words. You should also know about the composition of China's per capita GDP, including the years of rapid growth and the years of slow growth, as well as the changes in the ratio coefficient of our per capita GDP to GDP, so as to comprehensively consider, predict and even compare with the world's per capita GDP over the years to see when we can catch up with the world.
I hope it helps you!
