The purpose of this paper is to study agricultural-land inheritance and how the divided agricultural-lands through inheritance are being used in the suburbs, based on the field-research of Anjo in Aichi Prefecture.
　The conclusion is as follows.
　1) In proportion as industrialization and urbanization advance and the land-price increases, agricultural-land is more frequently divided through inheritance and lifetime gift than before. And the number of small-landowners increases, too.
　2) The inheritors resident in the same district inherited agricultural-land more frequently than the absentee inheritors in those days. Nowadays, however, absentee inheritors inherit agricultural-land as well as resident inheritors.
　3) Almost half of the agricultural-land inheritances of absentee inheritors were sold to the farmers who inhabited in other districts. And the rest of them (30-40%) are rented to mainly their resident brothers.
　4) The states of the agricultural-land inheritances of resident inheritors are as follows. More than one-third of them were diverted into the building-land for their houses. At the same time, more than one-third of them are cultivated by themselves. Others are mainly rented to their brothers or other people.
　5) The number of small-landowners is inclined to increase through partible-inheritance in the suburbs recently, which causes complexity of landownership relations. This means the increase of agricultural-land-management cost, and prevents agricultural-Iand-improvement investment.

　In this paper, it was shown how the U.S. dairy policies (marketing orders and support prices for manufacturing milk) and market power of farmers' cooperatives affect the degree of competition in the U.S. fluid milk market. This is the first development of a degree-of-competition measure for the U.S. fluid milk market. The estimated degree-of-imperfection parameter implies that there is small degree of imperfection which has been declining over time in the U.S. fluid milk market. It also implies that the degree of imperfection is larger in fall and winter than in spring and summer.
