摘要
蛛网模型刻画了某种商品在市场中的供求波动,是一种重要的典型动态经济学模型.本文对传统的蛛网模型加以改进,建立了需求函数和供给函数可以为线性函数或非线性函数的广义蛛网模型.并对其进行了动态分析与稳定性分析,得到了模型存在稳定均衡点的一些充要条件.
Cobweb model is a classical and important dynamic economic model. In describing fluctuation in the market price of single commodity. By improving traditional cobweb model, a type of generalized cobweb model, with demand and supply functions as linear or nonlinear functions is built, and dynamic and stability analysis of this model are carried out. We obtain several sufficient and necessary conditions, under which equilibrium price exists.
