About

Masahisa Fujita is a pioneering figure in spatial economics, whose foundational work has reshaped our understanding of how economic activity clusters in geographic space. His key research areas include agglomeration economies, urban systems, and the spatial distribution of industries, where he has made transformative contributions. Fujita is best known for co-developing the New Economic Geography (NEG) framework, which formalizes how increasing returns, transportation costs, and labor mobility drive the formation of cities and industrial belts. His seminal book, *The Spatial Economy: Cities, Regions, and International Trade* (co-authored with Paul Krugman and Anthony Venables), is a cornerstone of modern regional science, with over 5,000 citations. His work on the monopolistic competition model and the evolution of urban hierarchies has profoundly influenced both theoretical and applied economics. Among his notable achievements, Fujita served as President of the Regional Science Association International and received the prestigious Alonso Prize. His research continues to guide policymakers and scholars in understanding the dynamics of global economic geography, making him an indispensable reference for students and researchers alike.
