摘　　要：通过构建一个空间经济学分析框架,对集聚效应、拥挤成本影响城市结构演化的相关机制进行了系统探讨。结果显示:城市内部空间结构决定于集聚效应和拥挤成本的竞争均衡,城市中心的拥挤成本越高,城市空间半径越趋向于扩大;产业城镇化是支撑人口城镇化的持续动力,产业用地和居住用地混合分布是城市内部空间结构的必然;集聚产业的层次决定城市等级,产业可替代性越大、交易成本越高,城市等级越低。By constructing a theoretical framework of spatial economic analysis,the authors focused on correlation mechanism affecting urban spatial structure, including agglomeration effect, and congestion cost. The results showed that city internal structure depends on the competitive equilibrium of agglomeration effect and congestion cost, the higher congestion cost of urban centers, the larger the urban space size. Industrial urbanization is the sustained power of urbanization, the mixed distribution model of industrial land and residential land will be the normal situation of inner city space structure. The level of concentration industry determines city grade, the stronger the substitutability of the industry, the higher the transaction cost,the lower the grade of city.
