In China, the most popular city ranking is to divide cities into first-line, second-line, third-line and fourth-line. "Beishangguangshen" is recognized as a first-tier city, and "Beishangguangshen" refers to Beijing, Shanghai, Guangzhou and Shenzhen. Other cities, which belong to the second line and which belong to the third line, are basically inconclusive.
A first-tier city refers to a metropolis that plays an important role in national political, economic and other social activities and has the ability to lead and radiate. Mainly reflected in the level of urban development, comprehensive economic strength, radiation-driven ability, attraction to talents, information exchange ability, international competitiveness, scientific and technological innovation ability, traffic accessibility and so on.
The popular division of "first line and second line" has a great influence. In recent years, some research institutions have put forward the concept of "new first-tier cities", and on the basis of the four old first-tier cities of "North, Guangzhou and Shenzhen", Chengdu, Hangzhou, Chongqing, Wuhan, Suzhou, Xi, Tianjin, Nanjing, Zhengzhou, Changsha, Shenyang, Qingdao, Ningbo, Dongguan and Wuxi have been listed as "new first-tier cities".
