碳减排支持工具对低碳投资和碳减排效率的影响效应研究

Study on the Effect of Carbon Emission Reduction Support Instrument on Low Carbon Investment and Carbon Emission Reduction Efficiency

建立健全绿色金融体系,是绿色增长逐渐成为经济发展必然趋势下,高质高效解决绿色产业发展对金融强劲需求的必由之路。以理论研究为先导分析绿色金融创新工具实施成效,是从原理上及时评估其背后政策效应和调整方向的有效手段。通过构建基于新凯恩斯理论的四部门DSGE(动态随机一般均衡)模型,分析了碳减排支持工具实施前后,碳减排重点领域企业主要经济变量和碳减排效率代理变量稳态值变化,以及叠加不同冲击下的脉冲响应,并结合研究发现提出相应政策建议。

The establishment of a sound green financial system is a necessary way to address the strong financial needs of green industry development in a high-quality and efficient manner as green growth gradually becomes an inevitable trend of economic development.Analyzing the effectiveness of the implementation of green financial innovation tools with theoretical research as a guide is an effective means to assess the policy effect and adjustment direction behind them in a timely manner from the principle.By constructing a four-sector DSGE(Dynamic Stochastic General Equilibrium)model based on New Keynesian theory,the article analyzes the changes in the steady-state values of the main economic variables of the enterprises in the key areas of carbon emission reduction and the proxy variables of the carbon emission reduction efficiency before and after the implementation of the carbon emission reduction support tools,as well as the impulse responses under the superimposed different shocks,and puts forward the corresponding policy recommendations in the light of the findings of the study.
