摘　　要：本文从社会再生产循环及社会产品实现的角度对刘易斯二元经济模型进行研究。论文分别在封闭经济和开放经济条件下利用刘易斯二元经济模型中的不变劳动工资假定并结合产品市场出清进行论证。研究证明:由于只考虑劳动力市场而忽略产品市场的实现问题,刘易斯二元经济模型的结论——只有当二元经济越过了"刘易斯拐点",实际的劳动工资水平才能明显提高——无论是在封闭经济或开放经济条件下都是不能成立的。在长期经济增长过程中,无论是一元经济,还是向一元经济转轨的二元经济,劳动工资都应当随着劳动生产率的提高而相应提高。This paper analyzes the dual economy model by Lewis according to the idea of social product reproduction and its realization. The presumption of constant wage in Lewis model is falsified in the closed and open economy respectively by considering the product market. This study finds that the proposition of Lewis that the real labor wage could raise evidently only when the dual economy has passed the ＂Lewis turning point＂ cannot stand whether in the condition of closed economy or open economy, as Lewis ignored the analysis of products but only focused on the labor market. In the long term of economic growth, whether it is single or dual economy, the labor wage should raise as long as the labor productivity increases.
