This paper provides a detailed examination of the construction of Hong Kong International Airport (HKIA). The paper begins by reviewing recent work which has reconceptualised how airports are understood in spatial terms. It then describes the development of Hong Kong’s new airport, discussing the spatial format of the new airport design at HKIA, and the relationship between aviation and non-aviation uses. Next, it examines the impact of the airport on the rapidly shifting territorial politics of Hong Kong and the Pearl River Delta within the wider Chinese state. The paper argues that this case study must be assessed as part of a wider project of state territorial restructuring.
