马克思在《资本论》第二卷第三篇分析社会资本简单再生产时,把第Ⅱ部类分成必要生活资料和奢侈消费资料两个分部类,并分析了两个分部类的可变资本价值和剩余价值在各分部类内部以及两个分部类之间如何实现的条件。与此相适应,对2000Ⅱc和2000Ⅰ(v+m)也作了相应的分割,指出:在2000Ⅱc中“有1600用来交换必要生活资料的生产资料,有400用来交换奢侈品的生产资料。”①在2000Ⅰ(v+m)中,“(800v+800m)Ⅰ作为a的必要生活资料的生产资料=1600;(200v+200m)Ⅰ作为b的奢侈品的生产资料=400。”②但马克思没有进一步具体分析分割后的Ⅰ(v+m)和Ⅱc如何实现,因为这和第Ⅱ部类两个分部类的可变资本价值和剩余价值的实现条件是一样的。马克思在分析Ⅱa400m的1/4和Ⅱb100v的实现条件时指出:“(这同样适用于第Ⅰ部类劳动力的出卖;因为和Ⅰ(v+m)交 Marx analyzes the simple reproduction of social capital in the second volume, third volume of Capital, dividing the second category into two sub-categories of necessary living materials and luxury consumption data, and analyzes the two sub-sectors of variable capital The conditions for how value and residual value are realized within each segment and between the two segments. Correspondingly, 2000IIc and 2000Ⅰ (v + m) are also divided correspondingly. It is pointed out that in 2000Ⅱc, “there are 1,600 means of production used for exchanging necessary living materials and 400 means for exchanging the means of production of luxury goods. ”① In 2000 I (v + m),“ (800v + 800m) I as the means of production of the essential means of a = 1600; (200v + 200m) I as the means of production of b = 400. ” Marx did not further concretely analyze how the post-segmentation I (v + m) and IIc are implemented because of the same conditions for the realization of the variable capital value and the residual value of the two subsectors of the second category. In analyzing the conditions for the realization of ¼ and ½b100v of Ⅱa400m, Marx states: "(This also applies to the sell-off of labor in Part I; for I and I (v + m)
