摘要
本文基于Lyapunov稳定性理论以及差分方程的求解,讨论了蛛网模型的稳定性问题,结果表明,若满足|μ|<|β|,且(λ-a)/β2[λ-a+2μP(t)]<0时,蛛网模型是稳定的,此时商品的价格稳定在均衡价格,而当条件不满足和其它情形时,蛛网模型不具有稳定性。
The problem of stability analysis of cobweb model is studied in the paper ,based on Lyapunov stability theory and difference equation solving . The result prove that if it meet the following conditions:| | <| |and ( )]<0, then the cobweb modle is stable.
