本稿では「労働価値」の概念が機械制大工業という技術的条件をも前提としていることを説明す る。なお, こうして労働価値説を「証明」することは, マルクスの基本定理を「労働搾取の理論」として承認するうえでも重要である。また, そのために は人間の生産活動が最適な投下労働量の決定行動として行われているとの理解を示す必要があり, それにはさらに限界原理が基礎になければならないと本稿は考える。このため, 本稿における労働価値説の証明は限界原理に基づいて行われる。 The anti-Marxist criticism of the Fundamental Marxian Theorem (FMT) is based on the assertion that this proof can be understood as a "natural-resources exploitation, "if we assume, for example, that there is a "natural-resources theory of value." Therefore, Marxists

... ld prove not only exploitation but also the labor theory of value itself, and for that purpose, this paper aims to prove the labor theory of value mathematically by focusing on the historically conditional proportionality between labor inputs and the amounts of products that are assumed in the labor theory of value. By this proof of conditional proportionality, we show that the marginalist principle does not disturb the labor theory of value in capitalism at all. Furthermore, the marginalist principle is important to show that the labor process as a subjective optimization process that is not impelled by the sun but only by human beings. In this way, we use the anti-Marxist's marginalist principle to object to the anti-Marxist criticism of the labor theory of value.
