中国转型期中心城市城乡关系演变

2000年以来中国开始进入城乡互动与统筹发展的转型期.以中国中心城市为样本,城乡经济增长与城市化为研究视角,中心与外围区域为空间范围,利用时间序列数据,采用多元变量分析模型方法,对中国区域中心城市城乡关系要素变化进行了动态分析,建立了中心城市城乡关系模型,划分了中国中心城市城乡关系地域类型.研究结果表明:中心城市外围县区的固定资产投资、经济总量、工业生产的增长速度开始超过中心市区,经济要素过度集聚中心市区的格局发生转变.但中心城市外围县区的公共设施与基础设施供给能力与中心市区仍有较大差距,公共设施与服务的非均等化是中国城乡统筹发展的关键性障碍因素.依据城乡要素中心市区与外围县区空间变化,中国中心城市城乡关系可以划分为中心市区集聚型、外围县区快速成长型、中心外围相对均衡型、中心外围整体发展型等4种类型,反映出中国各中心城市城乡关系演变阶段、城乡结构特征与空间形态的地域差异变化.

The Evolution of Urban-Rural Relationship in Central Cities of China during Transformation Period

China has been in the stage of overall planning and interactive development of urban and rural areas since 2000. The present paper,taking the central cities as samples,mainly focuses on economic growth and urbanization. It takes the central and periphery areas of the city as the spatial scale,uses panel data to build a series of analytical models by multivariate regression analysis,and reveals the tracks and characteristics of urban-rural relation evolution of China’s central cities. The paper draws some conclusions as follows. First,the speed growth of fixed investment,economic aggregation and manufacturing production in periphery counties area shows that the pattern of economic elements gathered in the city center excessively is changing. Second,there is still a distinct gap of the public goods providing and infrastructure construction between urban and rural areas,which is the barrier of urban-rural integrative development. Last,19 city samples are divided into four groups: center gathering,rural area rapid growth,relative balance development and towards integrative development,indicating that central cities are going through different phases of urban-rural relation development featured by different structures and spatial morphology.
