Topic evolution in urban studies : tracking back and moving forward

This study is a bibliometric analysis of urban studies publications from 2001 to 2021 that unravels the evolution and growing complexity of the field. Although developed regions still dominate and lead this area of inquiry, urban studies led by Asian scholars have increased dramatically over the last decade. There is also topic diffusion from developed regions to less-developed regions despite some unique emphases within each region caused by their local socio-economic-ecological contexts. Climate change adaptation and sustainable development, inequality, and urban governance are receiving growing attention globally. The findings suggest the rising importance of cross-continent knowledge transfer and multi-disciplinary collaboration, particularly among urban studies, sustainability policies and management, public administration, and development studies. Also, urban researchers need to pay more attention to issues faced by many growing cities in developing economies in Asia and Africa as more of the world's population will reside in those urban settings in the coming decades.
