What cities are there on the 18 line?

Eighteen-tier cities generally refer to cities, counties, towns and villages with relatively low income levels outside the first and second tier. There is no uniform standard for the definition of several cities, but only a rough division.

The first basis of city division is political status, and the political status of a city determines which line city it is. For example, Beijing, as the national capital and the national political, cultural and educational center, will be a first-tier city.

The second basis of urban division is economic strength. Generally speaking, a city's economic strength will determine its economic status. In addition, cities are divided according to their size. The so-called city size means whether there are many people and resources in your city.

Urban scale division standard

Since the reform and opening up, with the acceleration of industrialization, China's urbanization has made great achievements, and the number and scale of cities have greatly increased. The original city scale division standard has been difficult to meet the requirements of the new situation such as urbanization development. At present, China's urbanization is in a critical period of in-depth development. In order to better implement the classified management of population and cities, and meet the needs of economic and social development, the standard of urban scale division is now adjusted to:

Based on the statistical caliber of urban resident population, the city is divided into five categories and seven grades. Cities with a permanent population of less than 500,000 are small cities, of which 200,000 to 500,000 are first-class small cities and 200,000 to second-class small cities; Cities with a permanent population of more than 500,000 and a population of less than 6,543.8+0,000 are medium-sized cities;

Cities with a permanent population of more than 6.5438 million and less than 5 million are big cities, of which more than 3 million and less than 5 million are type I cities, and more than 6.5438 million and less than 3 million are type II cities; Cities with a permanent population of more than 5 million and less than 6.5438+million are megacities; Cities with a permanent population of more than100000 are megacities.
