劳动力商品与人力资本

劳动力商品的价值决定于再生产劳动力的社会必要劳动时间，这一原理是正确的，但由于时代的局限，马克思在阐明这个社会必要劳动时间时忽略了劳动力商品生产中还有诸如学习训练所耗费的时间和精力这类活劳动投入，这会在生活资料的价值之外产生一个增殖额。对生产劳动力商品的社会必要劳动时间的重新理解，可以使工资劳动者收入的巨大差别、劳动力商品向劳动力资本的转化等重要经济现象在劳动价值论的基础上得到解释，对劳动力商品生产中活劳动投入的考察是人力资本理论的贡献，但这一理论因没有坚实的科学基础而不能完全理解这种投入的性质。

Commodity of Labour and Capital of Labour Power

The value of the commodity of labour force is measured by the social necessary time consumed in the reproduction of the labour. But due to the limitation of the age, Marx, while illustrating the theory of social necessary time, didn't explain the investment of such living labours as the time and energy consumed in study and training in the production of the commodity of labour. This results in an extra increase beyond the value of living materials. It is, therefore, necessary to have a better understanding of the social necessary time consumed in the production of labour commodity.
