Setting the Scene: Transnationalism and Spatial Diversification in Global Cities

This chapter sets the overall scene of the monograph by drawing out the different literature strands and scientific debates about and around urban diversification and transnational migration. It provides a critical overview of transnationalism and its intersection with urban studies. It navigates through various academic debates to highlight the relationship between transnationalism “from above” and “from below,” and how these perspectives shape global cities. The chapter emphasizes the particular importance of transnational professionals as part of the transnational migration in understanding the spatial diversification in global cities. It includes a specific focus on Tokyo as a global city, discussing its unique characteristics and relevance in the context of global urban networks and migration patterns. The chapter aims to bridge gaps in the research by integrating diverse literature strands, ultimately contributing to the broader debate on transnational spaces and socio-spatial diversification in urban settings.
