近年来,我国的货币政策空间有所收窄,这将不可避免地对货币政策力度产生影响,进而影响货币政策有效性。文章基于2000年第一季度至2022年第四季度宏观政策“三策合一”数据库的货币政策空间指数,使用非线性局部投影等实证方法,系统探究了货币政策空间对货币政策有效性的影响及其作用机制,得到了两点主要结论:第一,货币政策空间收窄确实是我国货币政策有效性下降的重要原因之一。第二,其背后的两条核心机制是“货币政策空间收窄→货币政策力度下降→货币政策有效性下降”和“货币政策空间收窄→市场主体信心减弱→货币政策有效性下降”。基于上述研究结论可知,要从跨周期的视角看待货币政策空间与政策力度的关系,在应对经济下行压力时,货币政策要敢于发力,而不应被货币政策空间过度束缚;同时,要加强对前瞻性指引等非常规货币政策的使用,增强市场主体的预期和信心,从而提升货币政策有效性。
货币政策空间收窄会削弱货币政策有效性吗?
