有关第二含义社会必要劳动时间的讨论是《资本论》研究的重要内容。考察马克思的原文可见,马克思仍然采用第一含义社会必要劳动时间来解释商品的价值,将过剩产品的价值实现视为价值规律的一种体现。马克思无意提出第二含义社会必要劳动时间。 The discussion on the second meaning of socially necessary labor time is an important part of the study of “capitalism.” In examining the original text of Marx, we can see that Marx still uses the first meaning of socially necessary labor time to explain the value of commodities and regards the realization of the value of surplus products as an embodiment of the law of value. Marx did not intend to come up with the second meaning of socially necessary working hours.
