定积分的经济学应用研究

Study over the Application of Definite Integral in Economics

随着社会的发展,经济学和数学这两个学科的联系也越来越紧密,利用数学知识去解决经济方面的问题也变得越来越普遍。从现在的经济理论来看,现在用数学知识来分析经济现象分为定量分析和定性分析。然而微积分就是数学的主要内容,而定积分又是微积分的基础,所以利用定积分来解决经济学中的问题也就变得非常的丰富。关于这方面的研究大概也就是一些函数的关系,比如说价格函数、需求函数、收益及成本函数等等,这些都是定积分运用到经济学中的重要的桥梁。要想优化经济的管理和经济的理论,在经济学中,定积分的运用是非常重要的。

With the development of society, the relationship between economics and mathematics becomes closer and closer, and mathematical knowledge is widely used in solving economic problems. Guided by current economy theory, nowadays analysis of economic phenomena with mathematical knowledge is divided into quantitative analysis and qualitative analysis. Calculus is the main part of mathematic while definite integral is the basis of calculus, therefore, it is of great interest to use definite integral to study and solve the economic problems through the links of functions, such as price function, demand function, profit and cost function. It is thus clear that the study of calculus is necessary in economics if we want to optimize the economy management and economy theory.
