摘　　要：长期以来,在我国大学经济学讲台上,流行着一种错误的经济学理论,而这一理论的产生,源自西方经济学的引进,因此必须甄别与扬弃。美国哈佛大学经济学教授N·格里高利·曼昆所著的《经济学原理》(简称《曼书》)中的可贷资金供给曲线向右上方倾斜,实际上是将单个银行的经济现象当作整个银行体系的经济现象,它忽视了银行体系内存贷款关系的变化和基础货币、原始存款与派生存款的相互转化,以及信用货币不会自动退出流通领域的特点,因此是一种既不现实又无意义的错误推定。《曼书》还将商品流通比喻为货币流通,实际上是忽视了商品流通具有运动上的有限性,以及货币流通具有运动上的无限性的特点,从而也违背了货币流通的基本原理,混淆了商品流通与货币流通的区别。而作为经济学教科书来说,以上两点都会对学生产生负面影响。For a long time, a false theory is prevalent in the teaching of economics in Chinese universities.This theory originating from western economics should be examined and modified. In Mankiw＇s Principles of Economics, the supply curve of loanable funds slopes upward. This argument takes what happens in an individual bank for an economic phenomenon in the entire banking system. It ignores the change of the relationship between deposit and loan in the banking system, and the conversion between base money savings and derived savings.Besides, it does not recognize the fact that credit currency never automatically withdraws from circulation.Therefore the argument is a pointless and unrealistic inference. Mankiw＇s textbook compares commodity circulation to currency circulation. This proposition ignores the limitation of commodity circulation, and disregards the fact that currency circulation is unlimited. The theory violates basic principles of currency circulation, confuses commodity circulation with currency circulation. As an economics textbook, these two points have negative impact upon students.
