The new town concept originated from the ideal city model of Ebenezer Howard and expanded from Europe to America in the 1900s. It has reemerged as a site for accommodating population from highly dense urban centers of China and India since the early twenty-first century. The massive infusion of public and private investments has enabled the emergence of new towns in China and India as planned centers of world-class residential, commercial, and work spaces. The rational goal of de-densifying the crowded central cities can lead to a more balanced distribution and use of resources across the metropolitan regions with more spacious housing for the growing middle class in China and India. Yet it is a relatively small number of the wealthy and mobile people who have turned out to be beneficiaries of the mostly high-end housing and well-developed transport infrastructure that evokes social and economic polarizations and political contestations. In this chapter, we will examine: (1) how these top-down planned and developed new towns have reshaped the urbanization process of the megacities in India and China, (2) the socio-spatial influence of these settlements on the central city as well as the surrounding rural areas, and (3) the expected and actual spatial users (both old and new residents) of the new towns? We address these questions by organizing two pairs of cases in a systematic framework: Anting New Town and Thames Town in Shanghai, China and Rajarhat New Town and the Kolkata West International City (KWIC) near Kolkata, India.
