| Abstract: | At first,the cobweb model in a differential equation's form is established under the condition of continuous time.Then,a condition for the stability of the cobweb model is obtained by analyzing the stability of equilibrium point of the differential equation model.Finally,a corresponding economical explanation and a concrete application of the differential equation model are given. |
