Abstract: The "paradigm" crisis in the economic circle not only happens in the field of western economics,but also appears in the area of Marxist economics.The on-going great discussion of Marxist theory of labor value in our country nowadays has been involved in the crisis of "paradigm".Holding on and developing the Marxist theory of labor value is the requirement of our times.But we should clarify the differences between two "paradigms" and follow the "paradigm" of Marxist economic theory.
