【摘要】:为量化分析经济政策不确定性对我国宏观经济波动的影响,本文在一个基于标准宏观经济理论的SVAR模型中,构建了一种由常规符号约束条件和特定零约束条件相结合的混合识别法,以同时识别出政策不确定性冲击和需求冲击、供给冲击、货币政策冲击等三种传统结构冲击。研究发现:(1)经济政策不确定性冲击并不是中国经济波动的主要因素,但它表现出类似于负向需求冲击的特征,且呈现通胀效应强于产出效应的中国特色;(2)样本期内,需求冲击是驱动中国经济波动的首要因素,供给冲击次之;(3)供给冲击是引致价格水平上涨的主要原因,货币冲击起到"推波助澜"的作用,而政策不确定性冲击则抑制了价格水平的进一步上升。本文研究为有关经济政策不确定性的宏观经济效应讨论提供了来自最大发展中国家的经验证据,也为"宏观经济政策要稳"的政策基调提供了支持。
[Abstract]:In order to quantitatively analyze the impact of economic policy uncertainty on macroeconomic fluctuations in China, this paper presents a SVAR model based on standard macroeconomic theory. In this paper, a hybrid identification method, which combines the conventional symbol constraint and the specific zero constraint, is constructed to identify three traditional structural shocks, namely, policy uncertainty shock and demand shock, supply shock and monetary policy shock. The study found that the uncertain impact of economic policy is not the main factor of China's economic fluctuation, but it shows the characteristics similar to the negative demand shock, and the inflation effect is stronger than the output effect in the sample period. Demand shock is the primary factor driving China's economic fluctuation, and supply shock is the second most important factor leading to the rise in the price level. Currency shocks play a role of "driving up the flames". The impact of policy uncertainty has restrained a further rise in price levels. This study provides empirical evidence from the largest developing countries for the discussion of macroeconomic effects of economic policy uncertainty, and also supports the policy tone of "macroeconomic policy should be stable".
