【摘要】In recent years,we have faced the situation of monetary deflation and economic slowdown. In order to solve these problems,we have applied some expansionary monetary and fiscal policies.And these polices did have some effects in stimulating effective demand and speeding economic growth,although,we still have a long way to the expected end.This treatise analyzes the reasons that led to the situation and pinpoints the facts that expecting results cannot be anticipated until the monetary and fiscal policies have been coordinated properly.
