　　【内容提要】经典的马克思主义经济学将资本有机构成和剩余价值率变化归结为影响利润率下降的主要因素。当代西方新马克思主义经济学对此问题的研究除了考虑这两个因素外，还考虑了真实工资率、劳动生产率、生产性劳动和非生产性劳动的比例变化、社会制度和冲突的积累，以及人口的统计学因素等。他们对利润率下降规律的实证研究采用了多样化的方法，得出了完全不同的结论：利润率或是上升的，或是下降的，或是具有不确定性。这些理论和实证研究为我国马克思主义经济学理论的创新提供了新的思路和方法。

　　The classical Marxist economics redeems that organic composition of capital and the rate of surplus value will be attributed as the main factors of profit rate decline. In addition to these two factors, contemporary Western neo-Marxist economics also takes into account the real wage rate, labor productivity, productive labor and unproductive labor ratio changes, the social system, the accumulation of conflict and population statistical factors. Their empirical research on decline of profit rate uses a variety of methods, drawing completely different conclusions: profitability could increase, or decrease, or be uncertain. The theoretical and empirical research provides innovative ideas and methods for China's Marxist economic theories.
