偏盛的经济学数理化倾向:现代主流经济学的缺失

Over-thriving Mathematization Tendency of Economics: The Deficiency of Modern Mainstream Economics

尽管数学对经济学的理论研究来说是一种必不可少的工具,但它毕竟属于工具性层次,是为更好地阐述思想提供服务的,从而是第二位的。如果过分拔高工具的地位,就会遮蔽我们对经济现象的理解,并使得经济学偏离其原初的研究目的。然而,基于根深蒂固的被殖民心态和市侩心态,主流经济学极力移植自然科学的研究思维和方法论,过分注重了工具的建设和使用,从而导致了思想的缺失。实际上,当前那些数学模型所能揭示的往往是一般性常识或者过时乃至错误的观点。

Mathematics works merely on an instrumental level for a better explication of thought, although it is absolutely necessary for theoretical research on economics. So it is secondary. If the instrumental status of mathematics is overstressed, it will shield our understanding of economic phenomena and deviate economics from its original objectives. However, the vigorous practice of mainstream economics is to transplant lines of thinking and methodologies from natural science, which tends to overemphasize the construction and utility of instruments, thus leading to the lack of thought. In fact, what mathematic models can offer is either commonsensical knowledge or outdated and even wrong ideas.
