The city ranking of "North, South, South and North" has always had a deeper meaning. First of all, from the comprehensive resources, business value, the city's people activity and lifestyle to consider the words. The status of Beijing and Shanghai should not be questioned. Why is Beijing ranked ahead of Shanghai? Perhaps Beijing has an advantage over Shanghai in that it is a political and cultural center. There are relatively more universities.
Shenzhen's development in the original is far less than Guangzhou. After all, Guangzhou is the old first-tier city.
And this new ranking, said to be slotted, I think it's more about the rise of the city's commercial appeal. Let's take the change in position between Beijing and Shanghai for a moment. Shanghai's overall ranking? Index is higher than Beijing, although the score is not very high, but the comprehensive Shanghai's degree of development. Catching up with Beijing is not impossible. In terms of the concentration of commercial resources, urban hubs, the activity of urbanites, the diversity of lifestyles, and future plasticity.
Beijing may not have the same development potential as Shanghai. This also has to do with Beijing's recent policies and the level of haze. Beijing is actually less accommodating to talent than Shanghai. But the difference between the two isn't really that great. Each has its own flavor. It's more likely that Beijing's talent policies and the city's people are less active than Shanghai's. That's why the 0.93 gap is so large. That's why it's a 0.93 difference.
There's also the comparison between Shenzhen and Guangzhou. With Shenzhen's net inflow of talent is increasing. The care for young people is also increasing. This also creates Shenzhen's business resources gathering degree and the city people active degree and future plasticity will be stronger than Guangzhou. But the gap is actually only 0.3 of the difference. It is not very obvious. Compared with Beijing and Shanghai, it is still weaker.
Simply put, the change from "north to south" to "north to south" may be a contribution to the new first-tier cities. But if you look at the data more closely, the change isn't really that big. If you study the data, you will find that there are some problems.
