不同资本账户开放程度下的中国财政货币政策效果分析

研究目标：分析不同资本账户开放程度下的中国财政货币政策效果及福利效应。研究方法：将内生化的政府支出（税收）政策以及包含汇率的价格（数量）型为主的混合货币政策一并纳入一个小型开放的DSGE模型。研究发现：随着资本账户的逐步放开，财政政策方面，减税政策刺激经济增长和促进就业的效果越来越好，政府支出政策刺激经济增长和促进就业的效果越来越差；货币政策方面，国内货币政策的调控效果及利率上升的跨期替代效应减弱。从社会福利损失的角度分析表明：无论是与内生化的政府支出（税收）政策组合还是与财政赤字政策组合，价格型为主的混合货币政策始终优于数量型为主的混合货币政策。研究创新：考察在高、中和低三种资本账户开放背景下中国不同财政货币政策组合的相互作用和经济效应。研究价值：为资本账户放开过程中合理地使用财政货币政策组合提供理论参考。
