总量均衡区间与宏观调控效应时滞

Aggregate Equilibrium Interval and Time Lag Effect in Macro-regulation

现代市场经济运行中由于调整供给量须耗费调节成本,因而传统分析中的"总量均衡中心点"两侧便分别存在着"低位临界点"与"高位临界点",这两点界定了一个特殊的总量均衡区间。总量均衡区间的存在,使宏观调控必然出现一种长期以来未曾引起人们注意的调控效应"时滞"。为缩短以致消除这种"时滞",宏观调控有必要确立并遵循"适度超前调控原则"。

In modern market economy , a lower critical point and an upper critical point are located on the two sides of the centre point of aggregate equilibrium to measure the adjustment cost needed in aggregate supply control, according to traditional economic analysis. The two critical points demarcate a special aggregate equilibrium interval. Unfortunately the existence of so-called aggregate equilibrium interval results in a special kind of 'time lag', which has been neglected so far in the macro-regulation. To shorten and eliminate this kind of 'time lag', 'the principle of moderate pre-emptive regulation' should be established and integrated into macro-regulation.
