首先 ,通过统一的政府采购 ,可以贯彻政府在总量调控方面的意图。政府根据宏观经济冷热程度及其发展态势 ,在可利用的弹性区间内适时、适量地安排政府采购行为 ,并产生政府支出的乘数效应 ,是调节总量的一种可选方法。比如 ,当经济偏热时 ,可适当压缩和推迟政府采购 ,减少社会? First of all, through a unified government procurement, we can implement the government’s intentions in controlling the total volume. According to the degree of macroeconomic hot and cold and its development trend, the government arranges government procurement behavior timely and appropriately in the available flexibility interval and generates the multiplier effect of government expenditure. It is an alternative way to adjust the total amount. For example, when the economy is overheated, government procurement can be properly compressed and postponed, and society can be reduced.
