本文以资本概念为考察主线,梳理了马克思对于资本概念的三重理解,它们分别作为对他人劳动产品的私有权的资本,作为一定量的积蓄的和储存的劳动的资本,以及作为资本家的资本。三重资本概念并非依次递进、相互扬弃的关系,而是在三者之间构筑了两重移动的跨越性批判:其一,在“私有权”与“资本一般”之间的移动,马克思以此来批判和超越空想社会主义与古典国民经济学家;其二,在“资本一般”与“资本家”之间的移动,马克思以此来完成对资本概念的客观维度与主观维度的整合,从而构筑了一个包含着界限以及对界限之扬弃的资本概念。从这一意义上说,资本概念自身包含着激进性。早期激进的马克思与晚期科学的马克思之间因此没有根本的差异。 In this paper, the concept of capital as the main line of investigation, combing Marx’s triple understanding of the concept of capital, respectively, as the private property of labor products to others, as a certain amount of savings and storage of labor capital, and capital as capitalists. The concept of triple capital is not a progressive and mutually discarded relationship, but a cross-cutting critique of the dual movement between the three. The first is between “private ownership” and “capitalization” As a result, Marx criticizes and surpasses utopian socialism and classical national economists. Second, in the movement between “capital general ” and “capitalist ”, Marx completes the objective concept of capital Dimension and subjective dimension, thus constructing a concept of capital that contains the boundary and the sublation of the boundary. In this sense, the concept of capital itself contains radicality. There is therefore no fundamental difference between the early radical Marx and the late Marxist.
