| The foreign and domestic relevant theories and methods and status quo of Commercial Spatial Structure Theory, Market Area Theory, and Commercial Location Theory are summarized. The shortage of these theories and methods, in author's opinion, is lack of idea of scale. On the basis of these theories, this thesis brings forward the notion of commercial micro-location and the related ideas: Micro-Location has the meaning of Three-Dimension, behavior, field and power, scheduling; it is not a kind of hierarchical location, but spatial location. Based on this conception, the author presents the definition of spatial competition and its connotation: the spatial competition that it is a kind of market competition based on consumer is different from industrial competition. And listed up some characteristics: dynamics, permanence, asymmetry and uncertainty of the results. According to what has been discussed above, the thesis focuses on the mechanism of formation of spatial competition from the viewpoint of cost: Distance Elasticity and Market Size Effect play an important role in spatial competition; At last, mode of commercial micro-location spatial competition is put forward. And some suggestions are brought forward. |
