Global Cities: Role in World Economy

The book Cities in a World Economy (1991), by Saskia Sassen, is a foundational work for understanding globalization and the strategic role that major cities play in the world economy. In her analysis, Sassen argues that global cities have moved beyond being merely centers of production or local exchange to become critical nodes in global networks of economic, financial, and technological power. These cities have evolved into key hubs for the management and coordination of global flows of capital, information, and talent. Sassen introduces the concept of “global cities,” such as New York, London, and Tokyo, which function as “command and control platforms” for the world economy.

Understanding Global Cities' Economic Role

These urban centers host the headquarters of multinational corporations, financial markets, and specialized service firms, allowing them to centralize decision-making and the management of global operations. Through these roles, global cities not only drive economic growth at the local level but also connect and facilitate economic integration internationally, consolidating their position as intermediaries in the circulation of goods, services, and capital. A key aspect of Sassen’s analysis is how globalization has intensified internal inequalities within these cities. While a segment of the population benefits from access to highly paid jobs in sectors such as finance, technology, and advanced business services, a large share of workers remains confined to low-wage employment, often in service sectors such as cleaning, hospitality, and transportation.

Socioeconomic Polarization in Global Cities

This division has produced significant socioeconomic polarization within global cities, creating spaces of extreme prosperity alongside areas marked by precarity and exclusion. Sassen also pays particular attention to the transformation of urban space that accompanies the rise of global cities. In many of these metropolitan areas, urban space is reconfigured to meet the demands of global capital, with the construction of skyscrapers, financial districts, and new transportation infrastructures designed to serve corporate elites. However, these processes frequently lead to the displacement of local communities, particularly in areas experiencing gentrification and sharp increases in real estate prices.

In addition to the concentration of economic power, Sassen highlights how global cities become laboratories of technological and financial innovation, where new forms of work, commerce, and services emerge. As these cities evolve, labor and social dynamics also change, creating an environment in constant transformation that shapes not only the global economy but also the everyday lives of millions of people. In summary, Cities in a World Economy provides a deep understanding of the relationship between urbanization and globalization. Sassen demonstrates how major cities have become essential actors in shaping the global economic system, while also examining the social tensions that arise from their transformation.

The book remains an essential reference for those interested in urban studies, globalization, and the economic impact of cities in an increasingly interconnected world.
