新世纪需要劳动价值理论乃至整个马克思主义政治经济学的新发展。文章通过对“劳动力商品”和劳动价值进行分析,指出劳动力不是商品,而是在一定时间内对劳动能力支配权的出租,工资则是劳动能力的租赁收入;劳动价值的实质是社会能量,而作为价值的社会能量具有不同于物质生产的、独特的自我增值规律;作为劳动价值的社会能量吸收的生产资料的能量转移构成劳动力创造大于自身价值的能量基础。 The new century needs the labor value theory and even the entire new development of Marxist political economy. By analyzing the “labor commodity” and labor value, the article points out that the labor force is not the commodity, but rather the renting of the control over the labor ability within a certain period of time. The wage is the rental income of the labor ability. The essence of the labor value is the social energy , While the social energy as value has a unique law of self-increment that is different from the material production; the energy transfer of the means of production absorbed by social energy as labor value constitutes the energy base for the labor force to create values ​​larger than its own.
