Stability Model on Website Competition and Cooperation of Establish and Analysis Evidence

Abstract

In this paper, through the establishment of the stability model to discuss the competition and cooperation of portal and search engine. For cooperation model of portals and search engines, By using Lotka-Volterra Mutualism model to describe and establish; for competition model of portals and search engines, then it is established using a prey item - Predator model with Lotka-Volterra of Logistic. As the paper designed to competition model of portals and search engines, from the mathematical analysis the stability of the model, and prove the global stability of the model, then given a series of competitive strategy for portals and search engines.
