The concept of “global city” was coined by the sociologist Saskia Sassen in her book The Global City (1991). In short, they are relevant cities for the world order , that is to say, model cities of contemporary global capitalism .

These types of cities are contemporary equivalents to the city-states of antiquity . In fact, many of them have political and administrative autonomy, or even their own Constitution that determines their laws .


Global cities are generally cities of international importance and renown . They occupy an extensive urban platform (and therefore with a huge population ) and play an active role in the economic, social and technological flow in their region, or even on the planet .
