总量均衡区间及其主要特性

Aggregate Equilibrium Interval and its Main Features

总量均衡区间是现实宏观经济运行中的一种特殊现象。总量均衡区间中的均衡属非均衡学派所主张的广义均衡,其特点表现为这是一种总供给与总需求存在一定差异、二者不完全相等情况下的总量均衡。静态地看,总量均衡区间是一个该区间内某相对稳定的总供给量与区间内无数个可能的总需求量均保持着均衡状态的特殊区间;动态地看,总量均衡区间则是一个随总需求变动而相应移动的区间。宏观调控对总量均衡区间的主要作用可一般地表述为:由宏观调控主导的总需求变动将引领总量均衡区间作相应的移动。正确认识总量均衡区间的特性对提高宏观调控质量与水平具有重要现实意义。

Aggregate equilibrium interval is a special phenomenon in macro economy, and it is not generalized equilibrium proposed by non-equilibrium scholars. The feature of aggregate equilibrium interval lies in that there is a certain discrepancy between overall supply and demand and there is no absolute equilibrium between them. Statically, it is a special interval in which there is equilibrium between overall supply and numerous possible demands. Dynamically, it is an interval which is flexible in accordance with the changes in the overall demands. The influence of macroeconomic control is realized by the changes of aggregate equilibrium interval according to the changes of overall demands caused by macroeconomic control.
