摘要
PPP机制有利于增强财政政策和货币政策实施的有效性。本文构建具有PPP机制的NK-DSGE模型,进一步研究PPP对宏观经济政策效应的影响,结果显示:在PPP机制下,社会资本参与公共基础设施建设或公共服务,不仅促进了就业水平和经济增长水平的提升,还利于缓解政府的债务负担;进一步对货币政策、财政政策的影响进行动态模拟比较分析,发现在PPP机制和非PPP机制下对宏观经济变量的冲击响应方向,PPP机制起到了政策“放大器”的作用,在PPP机制下政策效应更为显著。
The PPP mechanism is conducive to enhancing the effectiveness of fiscal and monetary policies.This paper constructs a NK-DSGE model with PPP mechanism to further analyze the regulatory effects of macroeconomic policies,and the results show that:Under the PPP mechanism,the participation of social capital in the construction of public infrastructure or public services can not only promote the level of employment and economic growth,but also help alleviate the government's debt burden;Further,through dynamic simulation and comparative analysis of the impact of monetary policy and fiscal policy,it is found that PPP mechanism plays the role of policy"amplifier"in the impact response direction of macroeconomic variables under PPP mechanism and non-PPP mechanism,and the policy effect is more significant under PPP mechanism.
