结构动力机制视角下的城市网络解释框架

中心地理论采用的是规模—等级分布体系。然而,新时期出现的一些新特征显然无法沿用中心地理论进行解释,如信息技术对城市体系的重构、基础设施网络对时空距离的压缩等。城市网络研究强调外部连接对城市发展的重要作用,可很好地解释城市与城市之间的关联特性,因此对城市与城市之间的关系研究已逐渐从城市等级转向于城市网络研究。通过构建社会分工、技术进步、地方背景三者相互作用的概念性解释框架,阐述城市网络的作用机制。在城市网络解释框架的基础上,提出了单个城市的网络化生存策略—界面交互模型,阐述单个城市与城市网络中其他城市的联系方式与互动关系。

City network studies: A conceptual explanatory framework

Although central place theory based on rank-hierarchy distribution considers that relations between cities are unilateral and asymmetrical, it can be widely applied in studies on complicated urban spatial changes, such as urban system restructure caused by information technology, temporal and spatial compression in terms of ameliorating infrastructure network, due to lack of insufficient explanation. In contrast, city network studies focus on the fact that inter-relations between cities are important to urban development, and the network analysis method has advantages of explanation of city hierarchy. In this paper, an explanatory framework, consisting of three concepts of social division, technological progress and local context, is constructed. The authors indicate that these three concepts can explain the mechanism of city network interaction system. Hence, interface interaction model is established. Moreover, based on explanatory network theory, this paper proposals existence strategies--interface interaction model as to single city in networked city system, and elaborates the contact and interaction between single city and other cities in the city network.
