This paper examines the method of living management theory by Okuma Nobuyuki, focusing on his “apportionment” concept. Economic subjects have a capacity for allocating resources for their daily life and commercial production. This idea, found in various economic theories, was linked with the actions-choice-theory of I. Kant and the economic-constitution-theory of O. F. Gottle. Thus, it was shown that living managing subjects have a capacity and requirement for appropriately allocating time, money, energy, other goods and services, ascertaining the necessity, and observing the general economic conditions. In the present framework for living management, the “consideration” by living managers is important. However, when it is overestimated, a particular family member might severely be blamed for his/her responsibilities, and the stable development of living management might be hampered. To overcome the deficiency, considerations of decision-making or dialogs are useful. It is also important that one should refer not only to individual homes, but to variations in the decision processes by living managing subjects under the environments where the relations with other homes, cooperating systems, administrative institutions, etc. might develop.
