扩展的总需求总供给模型——一个阐释我国宏观经济运行的分析框架

Extended AD-AS Mode——An Analytic Framework that Interpret Macroeconomic Practice of our Country

本文在附加预期的菲利普斯曲线基础上,通过引入可变的技术进步变量,修正了新古典的总供给曲线,指出除预期的通货膨胀率、产出缺口外,技术进步也是影响总供给曲线的重要变量;同时将总需求曲线扩展到开放经济条件下,从而推导出了“通货膨胀率——产出增长率”系统下的总需求总供给模型。作为对扩展后模型的检验,本文利用该模型阐释了我国宏观经济运行中的“高增长与低通胀并存”现象。

Based on Phillips curve that affix expectation, this article mend the neo-classical aggregate supply curve, by introducing the variable of technological progress. It indicates that technological progress is also an important variable to aggregate supply curve besides expectation inflation and products deficit. By applying aggregate demand curve into open economy, the author deduces a model of aggregate demand and aggregate supply under the system of ＂rate of output increase - rate of inflation＂. As a testing of extended model, the rectified model interpret the phenomena of the ＂co-exist of high growth rate and low inflation rate ＂ in our country.
