Within the context of broad literature on cross-border flows for higher education, this article examines the distinctive case of mainland Chinese students in Hong Kong and Macau. These territories are a sort of bridge between the fully domestic and the fully international. Hong Kong and Macau higher education plays a dual role, as a destination in itself for higher education and as a stepping-stone for students' further international development. Patterns in Hong Kong are slightly different from those in Macau, and the territories may thus be usefully compared with each other as well as taken as a pair for comparison with other parts of the world. The paper begins by noting the literature on the ways that push and pull factors influence student mobility, and then turns to motivations in pursuit of academic and professional growth, economic benefit, individual internationalisation, and enhanced social status. The paper shows that flows of mainland Chinese students are driven by both excess and differentiated demand. Analysis of the distinctive features of this pair of territories adds to wider conceptual understanding of the nature of cross-border flows for higher education.
