Abstract
This study examined changes of forest management after 1960, and considers the causes of change from the viewpoint of new institutionalism, focusing on two organization forms of forestry, the family management and the enterprise management. First, we examined the changes of ownership, silviculture, and felling conducted by each organizational form. The results reveal that 1） the ownership and the felling conducted by enterprises have increased gradually, and 2） the silviculture conducted by family management consistently have comparative advantage. It was thought the expansion in scale of forest-product industry gives the enterprise management of forestry advantage due to lower transaction costs. Second, we investigated decision making by family forest owners with several mail surveys data. The results show that only a few family members except owners join decision making in the family management. It was considered such situations influence the comparative advantages of family forest management.
