摘要
差分方程模型是一种重要的确定性离散模型,其中较常用的有N阶常系数线性非齐次差分方程模型,用待定系数法解此类方程,研究此类方程在市场经济分析中的应用,给出蛛网模型的三阶差分模型。
Difference equation model is one of the important determinacy models.This paper discusses the solution of linear constant coefficient nonhomogeneous difference equations with undetermined coefficient method.In addition,the applications of such equations in analysis of the market economy are introduced and the third-order difference model of cobweb model is given.
