Saskia Sassen’s Global Cities and Transnational Networks

Saskia Sassen, a well-known sociologist, introduced the concept of “global cities” to explain how certain cities around the world have become the key centers of power, economy, and communication in the modern globalized world. Her work focuses on how globalization has changed the traditional idea of national borders and how large cities like New York, London, and Tokyo now function as global command centers that shape the flow of money, information, and people across countries. To understand Sassen’s ideas, we need to look at how cities have evolved from being local centers of trade to becoming global hubs that influence the entire world.

In earlier times, cities were mostly connected to their surrounding regions and served as centers of local governance and commerce. However, with the rise of globalization, technology, and international business, some cities have become deeply linked with one another through networks of finance, communication, and migration. Saskia Sassen calls these powerful and connected cities “global cities.” These cities are not only important for their own countries but also for the functioning of the entire world economy. They host the headquarters of multinational corporations, global banks, and international media networks. For example, financial decisions made in New York or London can affect markets in Asia, Africa, or Latin America within minutes.

According to Sassen, globalization is not just about nations interacting with each other; it is about cities becoming the main actors in global processes. She explains that global cities serve as command points for organizing the global economy. They are where important financial transactions take place, where advanced technology and information are produced, and where decisions about global investment are made. The people who work in these cities—such as bankers, software developers, lawyers, and consultants—form a new kind of global workforce that connects different parts of the world.

However, Sassen also highlights that these global cities are not just about wealth and power. They also show deep social inequalities. While they attract rich corporations and professionals, they also depend on large numbers of low-wage workers who support the system. Migrants who work as cleaners, drivers, security guards, and food vendors are essential to keeping the city running, yet they often live in poor conditions. This creates a visible contrast between luxury and poverty within the same city. For Sassen, this inequality is a central part of the global city model—it reflects how global capitalism creates both opportunity and exclusion.

Sassen’s theory also emphasizes the importance of transnational networks. These networks are not physical structures but systems of connection that link different cities and people across borders. They include financial systems, digital communication networks, transportation routes, and cultural exchanges. Through these networks, information, money, and even people move quickly from one city to another. For example, a business deal might involve offices in New York, legal teams in London, and manufacturing units in Shanghai, all coordinated through digital communication. This interconnectedness is what makes the modern world function smoothly, but it also means that events in one part of the world can immediately affect others.

She also explains that global cities are spaces where global and local meet. While they are connected to international systems, they also maintain local cultures, languages, and traditions. Immigrants bring their own customs and mix them with existing urban lifestyles, creating multicultural environments. This diversity gives global cities their unique character but also brings challenges such as cultural tension, identity issues, and competition for resources.

Technology plays a huge role in maintaining these global networks. The spread of the internet, mobile communication, and high-speed transport has made it possible for businesses and people to stay connected globally. Sassen points out that these technologies have changed the way work is organized. Many services that used to be tied to one location can now be outsourced or managed online. Yet, despite this digital revolution, the physical city remains essential. Important decisions still happen face-to-face in these major centers because human interaction and trust are still key elements of business and politics.

One of Sassen’s most important contributions is her idea that global cities represent a new kind of geography. Instead of thinking of the world as divided only by national borders, she asks us to think about the connections between urban centers. For example, New York might be more connected to London and Tokyo than it is to other American cities. This changes how we understand global power, as authority and influence are now concentrated in networks of cities rather than within nation-states alone.

Another aspect of her work focuses on migration. Global cities attract millions of migrants who seek better opportunities. These migrants create communities that maintain ties with their home countries while integrating into the host society. This creates what Sassen calls “transnational social fields,” where people, culture, and money move back and forth across borders. For instance, a family living in London might send money to relatives in Pakistan, invest in property there, and maintain daily communication through the internet. This shows how global cities act as nodes in human as well as economic networks.

Sassen also discusses the political importance of global cities. Because they are centers of power, they often become spaces of protest and social movement. People gather in these cities to demand justice, equality, and human rights. From environmental protests to movements for labor rights, global cities serve as stages for global activism. Their visibility and media presence make them powerful platforms for spreading ideas and influencing global debates.

In conclusion, Saskia Sassen’s concept of global cities and transnational networks helps us understand how globalization operates in the real world. She shows that cities are not just places where people live—they are engines that drive global economic, cultural, and political processes. They connect the local with the global, the rich with the poor, and the powerful with the powerless. But they also reflect the inequalities and tensions that come with globalization. Her work encourages us to see the city as a living system of global interaction, constantly shaped by flows of information, money, and people. Understanding her theory allows us to better grasp the complexity of modern life and the forces that shape our world today.
