Rather it sought to describe how non wage incomes are produced and how this aggregate is redistribute, the first of these being the substantive issue to Marx and the one he discusses in VolumeⅠ, while the latter is the surface manifestation known to all bourgeois economists and which Marx only deigns to consider in VolumeⅡ.

而是力图说明非工资收入是怎样产生和怎样分配的，其中前者是马克思在《资本论》第一卷中探讨的实质性问题，而后者是资产阶级经济学众所周知的表面现象，马克思只是打算在第2卷中考虑这个问题。
