The Lotka-Volterra model focuses on two inter-enterprise commerce platform competition, the model aimed at research how the size coefficient affect enterprise competition relations, we introduce three cases in the paper: the platform between the two companies mutually impact factor with a positive number represents competition for purely competitive relationship; the same is negative for the symbiotic relationship; one positive and one negative is a typical predator- bait relationship. After that the paper select Dangdang and Amazon China who both in book publication as a core business of e-commerce platform for enterprise as the research object and collect relevant data, empirical analysis by Eviews software, the current phase of the relationship between the two companies is typical prey- bait relations, Dangdang act as predators role and Amazon China act as bait for this conclusion.
