与传统的凯恩斯主义下的宏观经济研究方法不同，动态随机一般均衡模型（DSGE模型）开创了结合微观基础与宏观现实的先河，更加注重对于经济活动的均衡状态的变化研究。由于其具有逻辑一致性，前瞻性以及跨期性质，坚持使用全局视角，灵活使用数学工具等优势，被广泛应用于国家经济货币政策以及经济市场波动等的研究中。本文介绍了基本的DSGE模型及其理论框架，并且详细阐述其黄金解与最优解。对于DSGE模型的发展历史和研究成果做了客观的总结和评价。尽管DSGE模型受到了来自各界的声音，褒贬不一，但是不能否认其在经济活动研究中所起到的重要作用。近年来，DSGE模型被逐渐完善，尽量用简洁的模型捕捉宏观经济的重要特征。在求解方法方面也有了重大突破。

Different from the traditional Keynes macroeconomic research methods, the dynamic stochastic general equilibrium model (DSGE) is the first to combine the micro basis with the macro reality, paying more attention to the change of the equilibrium state of economic activities. Due to its logical consistency, foresight and intertemporal nature, its advantages of persisting in using the global perspective and flexible use of mathematical tools, it has been widely used in the research of national economic monetary policies and economic market fluctuations. This paper introduces the basic DSGE model and its theoretical framework, and expounds its golden solution and optimal solution in detail. The development history and research achievements of DSGE model are summarized and evaluated objectively. Although DSGE model has been criticized and praised by many people from all walks of life, its important role in the study of economic activities cannot be denied. In recent years, DSGE model has been gradually improved, trying to capture the important characteristics of macro economy with simple model.
