Abstract
A global city is a city having a strategic position in diverse domains, mainly economic, political and cultural at the world level and establishing a dynamic node of communications. Global cities as London, the second world city after New York, and Shangai, the fifth, are the leaders in the world as well as on the international market. To sum up, according to the definition of the Saskia Sassen, a global city is "one that tangibly influences global affairs in terms of politics, culture, and various socio-economic means." This year we studied spaces and exchanges, that is why it is interesting to ask us how global cities, as geographical spaces, can have an impact on the people and exchanges.
First of all, I will look at the impact of global cities on people everyday lives, before to mention the diversity and exchanges, and then, the future of global cities.
The global cities have real impacts positive as well as negative on the population in everyday lives.
At first, the positive aspects of a global city are obvious. The inhabitants have access to numerous services. Indeed, the strong economic development that knows the global cities, which are leaders in the economic world, allow these cities to invest in diverse infrastructures. Equally, the access to culture is another major positive aspect of the global cities, which propose a quality education on account of their world-class universities.
