摘要
在全球金融危机中,美国等主要国家的央行实施了零利率货币政策,并在零利率约束下求助于量化宽松等非常规货币政策工具。文章使用金融市场和宏观经济运行的各项数据并结合最新实证研究结果,对非常规货币政策的实际效果与理论效应进行逐一比较,对非常规货币政策的各种理论假设效应进行全面的验证。总体而言,非常规货币政策确实可以通过几个传导效应起到降低长期实际利率的作用,但是截至目前对信贷扩张以及刺激总需求的效果比较有限,在此基础上进一步探讨了非常规货币政策未如理想的原因、非常规货币政策理论效应存在的不确定性以及时滞等因素制约了其发挥更大作用。
In the global financial crisis, the central banks implemented zero interest rate monetary policy, also resorted to unconventional monetary policy such as quantitative easing at zero bound constraint.

Further, the paper explores policy is unsatisfactory. and stimulating aggregate demand is limit- the reasons why unconventional monetary
