The following literature review traces North American research on China's Qing dynasty (1644-1911) frontiers, focusing on the manner that these border regions have been conceived and explained over the past half century. This aims to be an over view of commonly-encountered perspectives rather than a comprehensive discussion of the development of this subfield of Qing studies. The essay suggests that recent generations of research on Chinese frontiers have been influenced by a basic model of American frontier settlement, as well as by reactions to, and innovations upon, this model. This approach has been adapted to fit China's Qing Empire, particularly historical conditions such as physiographic boundaries, territorial expansion, population growth, and population movement. More specific interpretative models vary, of which four important approaches will be discussed here: regional systems analysis, colonialism (including colonial representation), New Western History, and comparative regional study.
