用蛛网模型分析市场经济趋于稳定的条件

Spide Web Model and Condition for Market Economy in Asymptotic Stability

用图形方法建立了商品供求关系的蛛网模型，利用差分方程将蛛网模型的结果用公式表示出来，并对结果进行解释。将模型适当推广，可对市场经济调控起稳定作用。

Using graphic method, we have set up a spider web model for market economy. ItS result is also presented in formula by difference equation. The condition for market economy in asymptotic stability is discussed in detail.
