动态随机一般均衡模型全局非线性分析方法研究进展

Recent Development of Global Nonlinear Analysis in Dynamic Stochastic General Equilibrium Models

动态随机一般均衡(DSGE)模型是宏观经济学的主流模型。近年来,传统求解该模型的局部线性近似法的局限性愈发明显,而全局非线性方法逐渐兴起,在一系列前沿领域取得突破性进步,推动了宏观经济学科发展。本文介绍全局非线性方法的一般性框架及其优势,随后梳理该方法在货币政策、金融危机、结构转型中的经济周期等课题上的最新成果。全局非线性方法可以提高宏观理论和量化分析的准确性和可靠性,有力推动国内宏观研究的进展。

Dynamic Stochastic General Equilibrium Model provides the mainstream framework in mac-roeconomics.Recently,the deficiencies of linearization,its traditional solution method,become increas-ingly evident,while the global nonlinear method makes breakthroughs in a series of frontier fields,pro-moting the development of macroeconomics.We introduce the general framework and advantages of the global nonlinear method,and review its latest achievements in topics such as monetary policy,financial crises,and economic cycles during structural transformation.Global nonlinear method can enhance the ac-curacy and reliability of macroeconomic theoretical and quantitative analysis,effectively promoting the progress of macroeconomic research in China.
