How many cities are there in the world, large and small?

Haha, there is no such statistics, and neither the United Nations nor other agencies have investigated it. Here is information about China: According to the "Constitution of the People's Republic of China", the administrative regions of the People's Republic of China are divided as follows: (1) The country is divided into provinces, autonomous regions, and municipalities directly under the Central Government; (2) Provinces, autonomous regions Divided into autonomous prefectures, counties, autonomous counties and cities; (3) Counties and autonomous counties are divided into townships, ethnic townships and towns. Municipalities and larger cities are divided into districts and counties. Autonomous prefectures are divided into counties, autonomous counties and cities. Autonomous regions, autonomous prefectures, and autonomous counties are all ethnic autonomous areas. It also stipulates that "the state may establish a special administrative region when necessary": On July 1, 1997, the Chinese government resumed the exercise of sovereignty over Hong Kong and established the Hong Kong Special Administrative Region; on December 20, 1999, the Chinese government resumed the exercise of sovereignty over Macao and established Macao. Special Administrative Region. At present, China has 34 provincial-level administrative regions, namely 4 municipalities, 23 provinces, 5 autonomous regions, and 2 special administrative regions. As of December 31, 2004, there were: 23 provinces, 5 autonomous regions, 4 municipalities, and 2 special administrative regions; 50 regions (states, leagues); and 661 cities, including : 4 municipalities; 283 prefecture-level cities; 374 county-level cities; 1,636 counties (autonomous counties, banners, autonomous banners, special zones and forest areas); 852 municipal districts. Total: 34 at the provincial level, 333 at the prefecture level, and 2,862 at the county level.

In recent years, based on the expansion of globalization (ie global finance, telecommunications and transportation), "global cities" have become increasingly familiar. The term "global city" was first coined by Saskia Sassen in her 1991 work, as opposed to megacity (also known as megacity). [edit] General characteristics The definition of a global city is subjective, but global cities generally have the following characteristics: International and well-known (people generally say "Paris" rather than "Paris, France"). Be active and influential in international affairs (for example, New York City is home to the United Nations headquarters). A sizeable population (at least 1 million people in the center of a metropolitan area, typically several million). Important international airports (for example: London Heathrow Airport), serve as centers for international routes. Advanced transportation systems, such as highways and/or large bus transport networks, providing diversified transportation modes (underground rail, light rail transit, regional rail, ferries or buses). Asian cities need to attract foreign investment and establish relevant immigrant communities, such as Singapore, Shanghai, Hong Kong, Tokyo and Moscow. Western cities should have international cultures and communities (such as Chinatown, Little Italy, or other immigrant communities). International financial institutions, law firms, corporate headquarters (especially conglomerates) and stock exchanges, and play a key role in the world economy. Advanced communications equipment, such as fiber optics, wireless networks, mobile phone services, and other high-speed telecommunications lines, facilitate cross-border cooperation. For example, Taipei is the world's first wireless city. Internationally renowned cultural institutions such as museums and universities. A strong cultural atmosphere, such as film festivals, premieres, lively music or theater venues; symphony orchestras, opera companies, art galleries and street performers. Powerful and influential media with a global perspective, such as the BBC, The New York Times, Le Monde, AFP and Reuters. A strong sports community, such as sports facilities, local league teams, and the ability and experience to host international sports events, such as the Olympic Games, the Football World Cup or the Tennis Grand Slam. In Western eyes, London, New York, Paris and Tokyo are traditionally considered the "four world-class cities". At the same time, they are also seen as symbols of global capitalism. In recent years, some views have also included large cities in Asia, such as Hong Kong, Singapore, Shanghai and Beijing. Of course, different people will have different standards, which depend on everyone's cultural background, values ??and experience. In some developed countries, the rise of their suburbs, coupled with the continued migration of manufacturing to developing countries, has led to a marked decline in cities. Therefore, in order to promote urban revitalization, tourism and tax revenue, the governments of small cities and their voters have in recent years come up with the idea of ??building "world-class" cities. Extraordinary world-class urban architecture can bring a bit of success to a city, as Buenos Aires, Frankfurt, Sydney, Mexico City and Toronto are testament to. These cities have shown their size and influence. [edit] GaWC's List of World-Class Cities In 1999, the Globalization and World Cities Study Group and Network (GaWC), based at Loughborough University in Loughborough, Leicestershire, UK, attempted to Defining and classifying world-class cities. The list of world-class cities, outlined in the GaWC Survey Journal No. 5 [1], ranks cities based on the supply of "high-end producer services" by international companies, such as accounting, advertising, finance and law. GaWC's roster confirms three levels of world-class cities and several sub-rankings.

Note: This list is generally ranked based on the number of business offices of multinational companies providing financial and consulting services in the city, rather than the center of culture, politics, and economy.

Lawrence Phillips officiating. The meeting aimed to determine the definition of "global city" and the evaluation criteria included: city image, narrative, economy, planning and citizens' experience. The meeting will also explore whether only the known "four world-class cities" - London, Paris, New York and Tokyo - can enjoy the status of global cities; or whether fast-growing Asian cities or third world cities can be included in the world level city. [edit] Other criteria The GaWC roster is based on specific criteria, so other cities of global significance may not be included.

Here are some examples: Large population, both overall and in metropolitan areas Diverse electorate (page 99) Based on different indicators: Population, settlement (selective profile), mobility and urbanization Significant financial reserves/ Expenditure: GDP of city/region (data in ZIP archive) Stock market: index/market capitalization Headquarters of multinational companies Financial services supply, such as banks, accountants Employment status based on quality of life or city development Based on living index Based on personal wealth, such as billions Number of millionaires Remarkable transportation infrastructure: Airports with impressive passenger capacity (analysis) or cargo capacity Large and popular public transportation system Excellent railway use Road car use Important seaports Important technological performance/infrastructure: Remarkable skyline/skyscrapers Important facilities: Educational facilities such as universities (registration required), international student study research facilities Health facilities such as hospitals, medical laboratories Holy places of worship for world religions Headquarters of international organizations The city has UNESCO Organization of historical and cultural heritage High-quality cultural facilities: Famous museums and museums Famous opera companies Famous symphony orchestras Famous film centers and film festivals Famous theater centers International sports event venues, such as Olympic Games venues (Olympic Games/Tourism Analysis) Tourism Productivity: Visitor economy competition[edit] List of world-class cities ranked according to individual criteria City population (overall) Metropolitan area population Foreign-born population[4] Living index[5] Metro system annual ridership Airport annual ridership Number of billionaires[6][7] 1 Shanghai Tokyo Miami Tokyo Tokyo Atlanta New York City 2 Mumbai Mexico City Toronto Osaka Moscow Chicago Moscow 3 Karachi New York City Los Angeles London Seoul London London 4 Buenos Aires Mumbai Vancouver Moscow Mexico City Tokyo Geneva 5 Delhi Sao Paulo New York City Seoul New York City Los Angeles Los Angeles 6 Manila Delhi Singapore Geneva Paris Dallas Hong Kong 7 Moscow Kolkata Sydney Zurich London Paris San Francisco 8 Seoul Buenos Aires Abidjan Copenhagen Osaka Frankfurt Paris 9 Sao Paulo Jakarta London Hong Kong Hong Kong Philadelphia Tokyo 10 Istanbul Shanghai Paris Oslo St. Petersburg Las Vegas Chicago
