Abstract
There is a controversy among Marxist feminists about the way to clarify the discrimination of women's labour in capitalistic societies. That is, between the unitary theory and the dualistic one. They are quite different in their attitudes toward the relationship of these two systems, namely the capitalistic economic system and the patriarchy one, though they acknowledge them as essential in clarifying the issue. This opposition, however, is not so strong as to fail to reach some sort of compromise if the capitalistic economic system is recognized as more flexible than it is supposed to be. The reason for the flexibility of the capitalistic economic system is shown here by reconstructing the value theory of Marxian economics. Furthermore, there is also investigated the possibility of compromise by examining the criticism on both sides.
