本文利用动态随机一般均衡模型,研究数量型和价格型货币政策背景下,财政政策应对不利外部需求冲击的效果,研究结果显示:(1)无论在数量型货币政策背景下还是在价格型货币政策背景下,对出口恢复作用最大的财政政策工具都是出口退税率,然而其恢复作用都非常小,表明利用财政政策应对不利外部需求冲击时不应将主要政策目标设为恢复出口;(2)若以恢复总产出和就业为主要政策目标,在数量型货币政策背景下应对不利外部需求冲击的最优财政政策为增加政府消费,而在价格型货币政策背景下,财政部门则可以不采取任何应对措施。
This paper uses the dynamic stochastic general equilibrium model to study the effect of fiscal policy on adverse external demand shock under the background of quantitative and price-based monetary policy. The results show that: (1) Both in the context of quantitative monetary policy and price-based monetary policy In the background, the most important fiscal policy tools for export recovery are export tax rebate rates. However, their recovery effects are very small, indicating that the main policy objective should not be set to resuming exports when fiscal policies are used to deal with adverse external demand shocks. If the main objective of the policy is to resume total output and employment, the optimal fiscal policy to deal with adverse impact of external demand under the background of quantitative monetary policy is to increase government consumption. However, in the context of price-based monetary policy, the finance department may not take Any response.
