摘要: 自2008年全球金融危机爆发以来,经济学界有关经济学的反思一直不断。理论方面,宏观经济理论和模型以及“有效市场假说”的有效性成为争论的焦点;政策领域,关于财政政策的有效性和通胀目标的设定出现了重大分歧;研究方法上,围绕着数学与经济学之间的关系以及经济学模型化方法纷争不断。然而,反思中也呈现出共识因素,从而揭示了经济学未来可能的发展方向。理论上,金融因素及更为现实的市场缺陷和摩擦因素将更多地被纳入经济学理论和模型中进行讨论,并且处理这些因素的模型也将更趋多元化;政策上,亟须发展出一套理论框架为财政政策和更为广泛的货币政策提供理论依据,货币政策将回归到数量工具、价格工具和其他工具并用的传统;方法上,超越数学的更为广泛意义上的多样化技术工具将积极发挥作用,模型会向更具现实性因而也更为复杂化的方向发展。除了危机的外部冲击外,经济学的这种路径转向可能还需要该学科内部制度性激励结构的相应变革。

Abstract: Since the outbreak of global financial crisis in 2008, the economic circles had been reflecting on economics continuously. The validity of macroeconomic theories and models as well as“the efficient market hypothesis”had become the focus of the debate.There was a significant divergence of the validity of fiscal policy and the setting of inflation target on economic policy.There had been continuous disputes on the relation between mathematics and economics as well as the method of economic modeling in methodology. However, the future development direction of economics had been showed in the reflection. Theoretically some financial and more realistic factors should be included in economic theories and models,and the models of dealing with these factors are to be gradually diversified. A set of theoretical framework should be urgently developed to provide a basis for fiscal policy and a wider range of monetary policy. Monetary policy would return to the tradition of diversified tools. Respecting method, diversified technical tools in a more extensive sense beyond mathematics would play a positive role and models should become more realistic and complex. Besides the external impact of crisis, the redirection of economics would possibly need corresponding transformation of internal institutional incentive structure in the subject.
