经济学中两个易引起困惑的基本概念的解析

需求和需求量是经济学中两个不同的概念。在需求理论中,同样一些因素,有的人把它们称作“影响需求的因素”,有的人则称为“影响需求量的因素”。这不仅会让人感到困惑,而且还会影响到对“需求量的变动”和“需求的变动”概念的理解。要解决学习需求理论时会遇到的这两个前后有联系的问题,需要我们从需求数量变动和需求函数关系变动两个角度去进行分析。

Analysis on two Basic Confusing Concepts in the Economics

"Demand" and "quantity demanded" are two different concepts in Economi cs. In the Theory of Demand, even for the same kind of factors, some refer to th em as "factors influencing demand", while others call them "factors influencing quantity demanded". It may not only be confusing, but also has some impact on th e understanding of "shift of quantity demanded" and "shift of demand". To solve these two inter-relating questions that we may come across when studying the The ory of Demand, we need carry out analysis from the following two aspects, namely "shift of the quantity demanded" and "variation of demand function".
