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．

Keywords: City-based Urbanization, Town-based Urbanization, Non-agriculturalization

摘要： 基于城市化的演进规律与时空条件,在将城市化分解为广义与狭义两个层次的前提下,重构了广义城市化认识框架下不同发展阶段的三种城市化形态及其演进关联,据以阐析中国城市化实践过程中存在的两个偏误。同时,基于对城市化内涵的剖析,阐明城市化是多重要素集聚的产物,城市化的演进理应以非农化为先导。研究认为,尽管中国的城市化在整体上已进入中期加速阶段,但鉴于区域发展的不均衡性及制度变革的不彻底性,中国城市化的多元发展格局与多重实现路径亦将伴随其间。因此不应一概而论,需要在深刻认识城市化发生原理与演进规律的基础上,针对不同区域的自然条件与人文环境进行适宜的城市化实践,才有可能促进中国城市化的稳定呈现与持续深化。
