基于供求视角的价格水平分析

供给和需求分析是微观经济学中最为基础的分析工具，价格水平则是宏观经济学中的一个重要概念。文章从货币作为交易媒介的角度看待商品的价格，在以货币的购买力来计量货币价格的基础上，采用供给和需求分析来研究价格水平的决定及其变动。研究结果表明：与决定单个商品价格的供求机制一样，价格水平也是由供求机制决定的；还验证了货币供给量的连续增加导致价格水平的持续上涨（即通货膨胀）这一共识。

An Analysis of Price Level Based on Supply and Demand Mechanism

Supply and demand analysis is the most basic analytical tool for microeconomics while price level is an important concept in macroeconomics. Based on the currency price calculation by currency purchasing power, this paper studies the determination and change of price level via supply and demand analysis regarding currency as an exchange medium. The results show that the price level is determined by the supply and demand mechanism just as that of a single commodity does, and that the continuously increasing money supply will result in a continuous ris- ing of price level （inflation）.
