The United Nations usually defines cities with a population of more than 1 10,000 as megacities. In 2065438+2004, 165438+2004 10, China, the State Council City issued the Notice on Adjusting the Criteria of Urban Size Division, which stipulated that cities with a permanent population of more than 5 million and less than10000 are megacities.
Megacities and small and medium-sized cities have some restrictions on population policies and household registration, which need to be improved to facilitate the further development of megacities.
The State Council recently issued "Several Opinions of the State Council on Further Promoting New Urbanization Construction", proposing to speed up the reform of household registration system and enhance the comprehensive carrying capacity of the city. Except for megacities and megacities, other cities are not allowed to set restrictions on settlement by asking for house purchase, paying investment tax and points system. The document pointed out that it is necessary to speed up the implementation of the household registration system reform policy. Focusing on accelerating the urbanization rate of registered population, we will deepen the reform of the household registration system, and promote the agricultural transfer population who have the ability to work and live stably in cities and towns to settle down with their families, enjoying the same rights and fulfilling the same obligations as urban residents.
Expand the division of labor in knowledge cities;
(1) Megacities: the urban resident population100000 or more;
(2) Megacities: the permanent population in urban areas is 5 million-10/00000;
(3) Big cities: urban resident population 1 10,000 to 5 million.
Among them, cities with more than 3 million and less than 5 million are I-type big cities, and cities with more than 6.5438 million and less than 3 million are II-type big cities;
(4) Medium-sized cities: the urban resident population is 500,000-1 10,000;
(5) Small cities: the urban resident population is less than 500,000,
Among them, cities with more than 200,000 but less than 500,000 belong to the first class of small cities, and cities with less than 200,000 belong to the second class of small cities.
