【摘要】 研究了经济贸易中的歧视现象，给出相应的数学模型．在生产函数由一次推广为m次（m≥1）的条件下，强调资本输入国只能将其输入资本产生价值的一部分偿还给输出国，相关结论、更合情理等方面都优于Becker关于歧视现象的数学模型．更多还原

【Abstract】 This paper studies the phenomenon of discrimination in trade and economic activities, and provides a correspondent mathematical model. This model is better than the Becker’s model of discrimination in extending the production function from 1 to m (m ≥1 ) in emphasizing the fact that the capital importing country pay back only part of the added value of imported capital to the capital exporting country, and in providing a more rational conclusion.更多还原
