2008年的金融危机提供了一个检验各派经济学理论的历史实验。本文依据对金融危机的观察,分别检讨微观、宏观、金融、制度经济学的理论和经济的度量,包括新古典经济学、凯恩斯经济学、奥地利学派在应对金融危机上的问题和局限。本文从方法论上分析了现行经济学规范的局限:一是企图模仿古典力学封闭系统的哈密顿模型,无法理解现实生命与社会在开放系统中的耗散结构和复杂行为;二是忽略经济和政治、生态等其他层次的相互作用。本文认为经济学未来的新规范是开放系统中的复杂经济学,可以整合现有各派经济学的合理成果。 The financial crisis in 2008 provided a historical experiment to test the theory of economic affairs in all factions. Based on the observation of the financial crisis, this article respectively reviews the theories and economic measurements of micro, macro, financial and institutional economics, including Neoclassical Economics, Keynesian Economics and the Austrian School in tackling the problems and limitations of the financial crisis. This paper analyzes the limitations of the current economic norms from the methodological point of view. First, it attempts to imitate the Hamiltonian model of classical mechanics closed system and can not understand the dissipative structure and complex behavior of real life and society in an open system. Second, ignoring economic and political , Ecology and other levels of interaction. This paper argues that the new norms of the future of economics are complex economics in the open system, which can integrate the reasonable results of the existing schools of economics.
