论西方经济学教科书的几个问题

On Some Basic Problems in Western Economics Textbooks

国内外经济学教科书在某些具体、细微的理论阐释方面,常有不够充分、细腻之处。在论述垄断竞争厂商的短、长期均衡时,不需要运用所谓的主观需求曲线,可以对垄断竞争厂商的长期均衡进行严格的数学证明;对生产者剩余可进行细腻的内在逻辑结构分析;规模收益不仅对应于生产规模的扩大,还应对应于生产规模的缩小;LM曲线的代数式也应获得更精确的表达。

Explanations of some specific and subtle theories in both Chinese and foreign economic textbooks are often not thorough and elaborate enough.It is unnecessary to apply the so-called Subject Demand Curve in explaining short-term and long-term equilibriums of producers in monopolistic competition industries.Long-term equilibrium of producers in monopolistic competition industries can be proved with precise mathematical methods;internal logic structure of supplier surplus can be elaborately analyzed;economies of scale does not only apply to capacity expansion but also to capacity shrinking;algebraic expression of the LM curve can also be more precisely stated.
