摘要
此数学模型是一个关于企业之间的竞争模型,它是假定生产相同产品,在相同环境下两企业竞争,根据它们在某一时期的盈利情况来建立的。运用微分方程的定性理论求出当时间延续下去时两企业的盈利将稳定于什么样的值,这样就可以从现在的情况来预测未来的发展结果。它有助于企业对自己的前途进行预测。从而改善生产状况,在竞争中生存。
This paper presents an economic model established by the authors for the competition between two enterprises which are supposed to be under the same condition of production and environment. The model was formed according to the profit of the two enterprises in certain period of time. Appealing to the qualitative theory of differential equations, the authors found the equilibrium point, at which the profit of these two enterprises became steady with theincrease of time. This in turn helps business people to make measures to improve their condition to run the business successfully.
