基于共生理论的临京临沪地区跨界融合发展对比研究

基于共生理论,以临京、临沪地区为例,利用Logistic共生函数对北京、上海与其周边城市共生关系进行识别,然后从共生环境、共生界面发展的空间分异特征探讨区域共生关系的形成机制。结果发现：① 与北京相比,上海与周边城市协调发展度更高,两大都市与周边城市均呈现互惠共生和寄生2种共生关系。② 行政等级管理体制的不对等是制约临京、临沪地区跨界融合发展的制度障碍,自上而下和自下而上的区域协调发展机制是两区域共生关系不同的重要原因。③ 临京、临沪共生界面要素联系格局均呈现明显的“交通廊道”特征。与其它周边城市相比,交通廊道重要节点或沿线城市与北京或上海的要素流联系更强,协同共生程度更高。

Development of Cross-border Integration of Beijing and Shanghai Based on Symbiosis Theory

The symbiosis of cross-border areas is the basic condition for realizing the integrated development of urban agglomerations. Based on the theory of symbiosis, this article takes Shanghai and Beijing as examples, Logistic symbiosis function is used to identify the symbiotic relationship between Beijing and Shanghai with their own neighboring cities. Meanwhile, the formation mechanism of symbiotic relationship is discussed based on the spatial differentiation of symbiotic environment and interface. Study found: 1) Compared with Beijing, Shanghai has a more coordinated development with its neighboring cities, and they have a mutualism and parasitism relationship with their surrounding cities. 2) Compared with Shanghai, Beijing has certain political specialties; the political rights between Beijing and its neighboring cities is unequal; Beijing’s market environment is mostly one-way interactive mode, which makes some limits for Beijing to form a good symbiotic relationship with its surrounding areas. However, Shanghai has a relatively equal communication environment with its neighboring cities; its police and market environment is mostly two-way interactive mode, which promoted its symbiotic relationship with surrounding cities. 3) Factor space contact structures of symbiotic interface between Shanghai and Beijing with their surrounding areas have obvious pattern of "traffic corridor" features. Compared with their cities, the elemental flow and symbiotic degree of Beijing and Shanghai and important traffic corridor nodes or cities along the route are higher.
