A
global city (also called
world city or sometimes
alpha city or
world center) is a city deemed to be an important node point in the
global economic system. The concept comes from
geography and
urban studies and rests on the idea that
globalization can be understood as largely created, facilitated and enacted in strategic geographic locales according to a hierarchy of importance to the operation of the global system of finance and trade.
The most complex of these entities is the "global city", whereby the linkages binding a city have a direct and tangible effect on global affairs through
socio-economic means.
[1] The terminology of "global city", as opposed to
megacity, was
popularized (not coined or invented) by the
sociologist Saskia Sassen in reference to her 1991 work, "
The Global City: New York, London, Tokyo"
[2] though the term "world city" to describe cities which control a disproportionate amount of global business dates to at least May 1886, to a description of
Liverpool by the
Illustrated London News.
[3] Patrick Geddes also used the term "world city" later in 1915.
[4] Cities can fall from such categorization, as in the case of cities that have become less cosmopolitan and less internationally renowned in the current era, e.g.,
Kaliningrad,
Russia;
Thessaloniki,
Greece; and
Alexandria,
Egypt.
Criteria
Global City or world city status is seen as beneficial, and because of this many groups have tried to classify and rank which cities are seen as 'world cities' or 'non-world cities'.
[4] Although there is a consensus upon leading world cities,
[5] the criteria upon which a classification is made can affect which other cities are included.
[4] The criteria for identification tend either to be based on a "yardstick value" ("e.g., if the producer-service sector is the largest sector, then city X is a world city")
[4] or on an "imminent determination" ("if the producer-service sector of city X is greater than the producer-service sector of N other cities, then city X is a world city").

- An advanced communications infrastructure on which modern trans-national corporations rely, such as fiberoptics, Wi-Fi networks, cellular phone services, and other high-speed lines of communications. For example, Seoul and Tokyo are known as the digital and technology capitals of the world.
- Health facilities; e.g., hospitals, medical laboratories
- Prominent skylines/skyscrapers (for example Shanghai or Hong Kong)[28]
- Cities' telephone and mail services, airport flights-range, traffic congestion, availability of water, train facilities, nearby parks, hospitals, libraries, police stations, etc.
Studies
GaWC studies
The first attempt to define, categorize, and rank global cities using 'relational data' was made in 1998 by Jon Beaverstock,
Richard G Smith and Peter Taylor, who all worked at that time at
Loughborough University in the United Kingdom. Together they established the
Globalization and World Cities Research Network. A roster of world cities was outlined in the
GaWC Research Bulletin 5 and ranked cities based on their connectivity through four "advanced producer services": accountancy, advertising, banking/finance, and law.
[5] The GaWC inventory identifies three levels of global cities and several sub-ranks. This roster generally denotes cities in which there are offices of certain multinational corporations providing financial and consulting services rather than denoting other cultural, political, and economic centres.
The 2004 rankings acknowledged several new indicators while continuing to rank city economics more heavily than political or cultural factors. The 2008 roster, similar to the 1998 version, is sorted into categories of "Alpha" world cities (with four sub-categories), "Beta" world cities (three sub-categories), "Gamma" world cities (three sub-categories), and additional cities with "High sufficiency" or "Sufficiency" world city presence.
The 2008 roster of leading Alpha, Beta and Gamma world cities is reproduced below; see the source for the complete roster:

Global Cities Index
In 2008, the
American journal
Foreign Policy, in conjunction with consulting firm
A.T. Kearney and the
Chicago Council on Global Affairs, published a ranking of global cities, based on consultation with
Saskia Sassen,
Witold Rybczynski, and others.
Foreign Policy noted that "the world’s biggest, most interconnected cities help set global agendas, weather transnational dangers, and serve as the hubs of global integration. They are the engines of growth for their countries and the gateways to the resources of their regions."
[31]
In 2010 the index was updated, and the top thirty ranked were:
[32]
Global Power City Index
The Institute for Urban Strategies at The Mori Memorial Foundation in
Tokyo,
Japan issued a comprehensive study of global cities in 2009. The ranking is based on six overall categories, "Economy", "Research & Development", "Cultural Interaction", "Livability", "Ecology & Natural Environment", and "Accessibility", with 69 individual indicators among them.
[33] This Japanese ranking also breaks down top ten world cities ranked in subjective categories such as "manager, researcher, artist, visitor and resident."

| 3 | Paris | 317.8 | Livability (1.) Accessibility (1.) |
| 4 | Tokyo | 305.6 | Economy (2.) Research & Development (2.) |
| 5 | Singapore | 274.4 | Economy (5.) Cultural Interaction (5.) |

World City Survey
In 2010 the London based consultant firm
Knight Frank LLP together with the
Citibank published a survey of world cities.
[34][35] The Wealth Report 2010, which includes the World City Survey, assesses four parameters — economic activity, political power, knowledge and influence and quality of life. The list aimed to rank the world´s most influential cities.
