摘　　要：蛛网模型是动态经济分析中的一个经典模型,本文讨论了其平衡点的稳定性,推广了已有模型中参数的取值范围,建立了测度微分方程模型,对新产品的畅销期限进行了预测.Cobweb model is the classical model in dynamic analysis. This paper discusses the stabil- ity of the equilibrium point of this model. The parameter ranges of function on existing model are gen- eralized, and the model of the measure differential equation is establishes. At the same time, the deadline of the salable new products is predicted.

关 键 词：非均衡 蛛网模型 扰动
