Abstract:

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.
