Abstract:Marx and Engels' Benefit Mechanism includes the benefit subjects, the benefit objects, and the measures to realize benefits. The three elements, following their intrinsic principles, interplay with each other so that the historic appealing from benefit subjects to the benefit objects is accomplished, leading to the historical liberation of the benefit subjects. In Marx and Engels' Benefit Mechanism, the reality of individual is the logic starting point; the material living conditions is the initial domain; while production is the measure of benefit realization. Marx and Engels' Benefit Mechanism reflects the methodology of integrating history with logic, and it is an effective method to handle the current benefit issues in China.
