一阶微分方程在经济学中的4个应用

Four applications of first order differential equation in economics

一阶微分方程的应用模型很多,尤其是微分方程在经济学中的应用,通过举例说明,它在分析商品的市场价格与需求量(供给量)之间的函数关系、预测商品的销售量、关于国民收入和储蓄与投资的关系问题及成本分析这4个方面的具体应用。

There are a lot of application models for first order differential equation,especially for differential equations in economics.In this article,by illustrating some examples,the first order differential equation has specific applications in four aspects as：analyzing the relationship between the market price and the demand quantity,predicting the sales quantity of the goods,analyzing the relationship between people’s income ＆ deposit and investment,and cost analysis.
