我国全域设区实践中的都市区化效应及模式——基于宁杭两市的比较

EFFECT AND MODEL OF METROPOLITANIZATION IN THE PRACTICE OF"DIVIDING THE WHOLE CITY INTO MUNICIPAL DISTRICTS"IN CHINA:BASED ON THE COMPARISON BETWEEN NANJING AND HANGZHOU

当前以全域设区行动为抓手,各大城市陆续开展行政区划调整,并超越通过撤县设区破除行政壁垒的传统认知,将“城区”过渡为“都市区”,逐步实现了自身行政、空间与功能的多元边界重构,使得都市区化成为我国大城市能级跃迁的重要选择。据此,本文基于南京和杭州两市实践,围绕各自行政、空间与功能边界的重构逻辑,梳理了两市通过区划调整实现拓空间、强实力、扩影响的基本路径,比较了两市在全域设区进程中所显现的都市区化效应,阐释了两市系统调整行政边界、科学延展空间边界、全面优化功能边界的都市区化过程,总结形成了“行政—空间—功能”和“行政—功能—空间”两类都市区化模式,以期为同类城市的都市区化实践提供参考框架与依据。

At present,with the action of"dividing the whole city into municipal districts"as the starting point,cities continue to carry out adjustments on administrative division,which transcends the traditional perception of breaking administrative barriers by turning county into district and transforms"urban areasinto"metropolis".Gradually,the reconstruction of the administrative,spatial,and functional boundaries is achieved,which makes metropolitanization an important option for the level transition of big cities in China.Therefore,based on the administrative,spatial,and functional boundary reconstruction logic of Nanjing and Hangzhou.this paper sorts out the basic path to expanding space,strengthening capacity,and expanding influence of the two cities through adjustments of administrative division,compares the effect of metropolitanization in the process of"dividing the whole city into municipal districts",and explains the metropolitanization process of the two cities formed by adjusting the administrative boundary systematically,extending the spatial boundary scientifically.and optimizing the functional boundary comprehensively.Finally,two models of metropolitanization,i.e.,"administration-spacefunction"and"administration-function-space",are summarized in order to provide a reference frame and basis for the practice of metropolitanization of similarcities.
