The purpose of this article is to analyze the conditions of the replacement of fixed capital under the normal course of extended reproduction. In extended reproduction under the constant rate of growth, the depreciation (D) exceeds the replacement (R). Here the condition of the replacement of fixed capital is that the additional investment in fixed capital is equal to the difference of (D-R) in the whole economy. Then the questions we must solve are as follows : (1) how does the additional investment become possible without restricting the replacement of each fixed capital, (2) does the total value of fixed capital grow larger by the reconversion of the depreciation fund into the additional inventment in fixed capital? In the first place we point out that in extended reproduction the age structure of fixed capital is multiple in the whole economy and also in an individual firm. The multiple age structure of fixed capital in an individual firm makes a certain part of its depreciation fund liberalized. The reconversion of this liberalized fund into the additional investment in fixed capital is the condition that makes the additional investment in fixed capital possible. The second thing to be noted is that the additional investment of (D-R) appears as a kind of new investment in fixed capital from the standpoint of the reproduction process of the aggregate social capital. In this respect, this investment and the accumulation of fixed capital are equally new investments in fixed capital. The difference between them is that by the former the total value of fixed capital doesn't grow any larger but by the latter it does grow.
