转型期中国城市内部空间重构: 特征、模式与机制

转型期中国城市内部经历了人口、经济和社会等方面的空间重构， 空间结构变得更加复 杂。中国城市人口郊区化速度在加快， 城市常住户籍人口和外来人口的空间重构存在明显差别， 城市人口空间重构过程的相似性特征减弱而差异性特征增强。对中国城市工业和商业空间重构 的分析表明， 郊区化和离心化力量发挥了重要作用。中国城市社会空间因子与社会形势密切相 关， 社会区类型越来越多样化， 社会区构成则经历了由单一到混杂的变化。20 世纪80 年代初中 国城市内部空间结构模式具有典型的同质性特点， 带有计划经济色彩， 而90 年代末的模式则是 市场经济发展的产物， 异质性特征突出， 而且带有多中心结构特点。

Restructur ing of Urban Internal Space in China in the Tr ansition Per iod: Char acter istics,Models and Mechanisms

Urban internal spatial structure in China is becoming more and more complex during the transition period when population, economic activities and social elements experienced a fast process of restructuring. Suburbanization of population accelerated in China in the 1990s compared with that in the 1980s. Great difference exists between the spatial restructuring of permanently registered population and that of external population. Generally speaking, the similarities of the spatial restructuring of population increased while the differences of it decrease. Analysis of the restructuring of urban industry and commerce shows that suburbanization and the centrifugal forces exert great influence on the evolution of urban internal spatial structure in the transition period. The factors of urban social space are closely related to the development of society. The types of social areas tend to vary and the components of each social area change from singleness to multiplicity. As a product of the planned economy, the model of urban internal spatial structure in the early 1980s exhibited more similarities than differences, with the feature of homogeneity, while that in the late 1990s was a product of market economy, exhibiting more differences than similarities, showing an obvious feature of heterogeneity and polycentric structure.
