Abstract: The paper develops a theory of urbanization which examines the concept of urbanization in two layers，general and special，establishes three forms of urbanization and their relationships in different stages of development in the context of general urbanization，and explains two sorts of misdirection in the
practice of Chinese urbanization． The paper argues that urbanization is a centralizing result of many factors，and urbanization needs to be preceded with non-agriculturalization． Chinese urbanization is now getting accelerated，but will present multiple and diversified patterns across China due to regional development disparities and institutional barriers in China． A sustainable urbanization in China needs to be framed in local contexts and practices．
