本文讨论了劳动生产率与工资和剩余价值率之间的数学关系,考察了剩余价值率的重要影响因素,即单位劳动成本。本文认为,经济全球化条件下资本输出可以提高剩余价值率,为资本带来相对剩余价值。资本输出产生的效应是多方面的,包括对投资母国和东道国的就业效应、工资差距效应以及政府财政效应等。国际资本自由流动改变了全球劳动力价值体系,对于固有的国际经济秩序形成了很大的冲击,迫使各国纷纷改革以适应全球化新形势。 This paper discusses the mathematical relationship between labor productivity and wage and residual value, and examines the important influencing factors of the residual value rate, that is, the unit labor cost. This paper argues that under the conditions of economic globalization, capital output can raise the rate of surplus value and bring relative surplus value to capital. The effects of capital output are manifold, including employment effects on the home and host countries of investment, the effect of wage inequality, and the government’s fiscal effects. The free flow of international capital has changed the global labor value system and has had a great impact on the inherent international economic order, forcing countries to reform one after another to adapt to the new situation of globalization.
