长江经济带空间结构演化及重组

The Formation, Evolvement and Reorganization of Spatial Structure in Yangtze River Economic Zone

在重新认识长江经济带的空间范围及空间结构内涵的基础上,运用空间数据分析的一般方法,获得了长江经济带空间分异的基本特征。经过独立发展阶段、区域集聚与链接阶段、行政经济区阶段和空间竞争与链接阶段等4个时期的发展,长江经济带形成了特殊的条形核心—外围—边缘结构,存在三大核心、一条主轴、一条辅轴、四条地方轴、一个外围地区和一个边缘地域。运用空间相互作用理论,从互补性、通达性和介入机会等方面分析了长江经济带空间结构形成与演化的基础。为加快长江经济带空间结构的优化,首先要求空间管理组织的创新,其次是空间结构要素的优化。一个以政府、城市管理与经营者和具有跨国或跨区域网络的精英企业三者组成的长江经济带空间组织与管理机构,是管理长江经济带的理想组织模式,只有当政府、城市管理与经营者和企业建立起三者协商与联合的机制,才能进行有效的空间管理。长江经济带的空间结构要素中,节点和通道是骨架,也是空间结构优化的两大关键要素。

On the basis of re-understanding the spatial scope and spatial contents of the Yangtze River Economic Zone （YREZ）, applying the usual spatial data analytical methods, the natural characteristic of spatial division of the YREZ has been attained. The special band-shaped core-periphery-edge structure of the YREZ was formed after the four developing periods of independent development, regional concentration and connection, administrative economic region and spatial competion and connection and so on. The YREZ has three cores, one main axis, one secondary axis, four locational axises, one peripherical region and one edge region. The basis of the formation and evolvement of spatial structure in the YREZ has been analyzed from complementarity, transferability and tervening opportunity and other parts by applying sptial interaction theory. To speed up optimization of spatial structure of the YREZ, we should bring forth new ideas in the regional organization of administration. Then the essential factors of spatial structure need to be optimized. One regional organization and administration mission, known as GCT model （G represents government, C stands for city administrators and T is transnational-corporations or transregional-corporations）, should be the most ideal organization model, which is composed of local government, city administrators and the master enterprises possessing transnational-corporations or transregional-corporations networks. When a mechanism of reaching unanimity through consultation and combination between the three bodies of local government, city and transnational or transregional-corporations is set up, spatial administration of the YREZ could be most efficient. Among the factors of spatial structure of the YREZ, the nodes and the passageway are the framework as well as the two most imoortant factors ootimizing soatial structure.
