摘　　要：在“三重压力”下,我国货币政策调控要实现“稳增长”和“防通胀”在水平值和波动率上的“双重稳定”,既要保持适度经济增速,又要防止通货膨胀快速上升,还要防止产出和通胀波动形成的经济风险。为此,文章使用了局部投影方法和VAR模型方法计算了数量型和价格型货币政策的冲击反应函数,以此刻画货币政策对产出增长率和通货膨胀率的水平值和波动率的动态效应。实证结果表明,数量型货币政策对经济增长率和通货膨胀率均具有水平值上的显著正向效应,同时具有降低产出波动而提升通胀波动的冲击效应;价格型货币政策也对经济增长率和通货膨胀率具有显著正向效应,同时具有降低产出波动率和通胀波动率的双重稳定功能。因此,当前货币政策操作仍然要以价格型货币政策为主,以此实现货币政策逆周期和跨周期调控功能。Under the“triple pressures”,China's monetary policy should achieve the“double stability”of“stable growth”and“inflation prevention”in the level and volatility,not only to maintain moderate economic growth,but also to prevent the rapid rise of inflation,and to prevent the economic risks caused by output and inflation fluctuations.Therefore,we use local projection method and VAR model to calculate the impulse response functions of quantitative and price-based monetary policies to characterize the dynamic effects of monetary policy on the level and volatility of output growth rate and inflation rate.The empirical study finds that quantitative monetary policy has significant positive effects on economic growth rate and inflation rate,and also has the impact effect of reducing output volatility and increasing inflation volatility;Price-based monetary policy has a significant positive effect on economic growth rate and inflation rate,and also has a dual stabilizing function of reducing output volatility and inflation volatility.Therefore,the current monetary policy operation should still focus on price-based monetary policy,so as to realize the counter-cyclical and cross-cyclical regulation of monetary policy.
