美国次贷危机引发了全球性的金融风暴,学术界对次贷危机成因的解释主要有金融市场缺陷、金融监管过于宽松、货币政策不当、房地产泡沫破灭、过度信贷与投机等,这些解释都没有触及次贷危机形成的深层次原因。马克思关于社会生产按比例协调发展规律和平均利润率规律在深层次上解释了此次次贷危机形成的原因及影响,揭示出脱离了实体经济的虚拟经济终将会重创实体经济,美国次贷危机实质上是对全球经济不平衡所做的一次大调整。在当代,马克思主义经济学理论仍然具有很强的现实意义。

The subprime crisis in the USA triggered the global financial crisis.The academic circles believe that the reasons causing this subprime crisis include defects in financial market,loosen financial supervision and management,improper monetary policies,destruction of real estate bubbles,excessive credit loan and speculation etc..However,all these are not the fundamental reasons for this subprime crisis.Marx's law of proportion-based harmonious development of social production and average rate of profit explain the reasons and influences of the subprime crisis in depth,and reveal that dummy economy separating from entity economy will definitely damage the entity economy finally.In fact,the subprime crisis in the USA is a great regulation of the imbalanced world economy.In the contemporary world,Marxian economic theories are still of great practical significance.
