Saskia Sassen: what makes a global city global

In her influential book The Global City: New York, London, Tokyo, Saskia Sassen analyzes the role of global cities as key hubs in the contemporary world economy. Published by Princeton University Press, the work explores how these three cities have evolved into crucial nodes for the flow of capital, information, culture, and political power. Sassen argues that, in the context of globalization, cities are not simply local environments, but are deeply interconnected and exert global influence across various economic and social spheres. One of Sassen’s main contributions is her concept of the “global city,” which refers to urban centers that perform crucial functions in the international economy, particularly in the management and distribution of financial capital.

According to the author, New York, London, and Tokyo stand out for concentrating the headquarters of major corporations, financial institutions, and international organizations, making them centers of global decision-making. These cities not only control monetary flows, but also information and services, placing them in a privileged position within the global economic system. Sassen also emphasizes that globalization has transformed the internal functioning of these cities. The increased mobility of capital and technology has generated growth in financial sectors and specialized services, while many manufacturing industries have moved to countries with lower labor costs.

Internal economic reconfiguration

This economic reconfiguration has produced a greater concentration of wealth in certain urban sectors, while other areas have experienced increasing labor precarity and social inequality. In this way, globalization has not only strengthened the global relevance of these cities, but has also intensified their internal tensions. The author also highlights the importance of global networks that connect New York, London, and Tokyo with other cities and regions around the world. These networks enable the circulation of capital, goods, people, and information at an unprecedented speed, increasing the interdependence between global cities and the rest of the world.

However, Sassen warns that this flow is not always equitable. While certain areas within these cities benefit from their integration into the global economy, others experience processes of exclusion and marginalization due to the concentration of power and resources in the hands of a global elite. Another key aspect that Sassen addresses is the role of global cities in culture and political power. These cities are not only economic centers, but also spaces where cultural trends emerge and major political decisions are made.

Culture and global political power

The presence of international media, non-governmental organizations, and diplomatic forums in these cities reinforces their influence beyond national borders, consolidating their status as axes of global power. Moreover, their cultural diversity and their ability to attract talent from around the world give them a particular dynamism, which in turn strengthens their appeal as cultural and social epicenters. In conclusion, The Global City: New York, London, Tokyo by Saskia Sassen provides a comprehensive view of how global cities have acquired a prominent role in the world economy and politics. Through her analysis of New York, London, and Tokyo, Sassen illustrates how these urban centers have been shaped by globalization and, in turn, how they influence the globalized world.

Although their position as nodes of power and capital grants them enormous advantages, they also face significant internal challenges, such as social inequality and economic fragmentation, which reflect the complexities of living in a truly global city.
