The purpose of this study is to examine whether farmers are likely to reduce production costs by choosing between new technologies (6-row beet harvester and 6-row beet transplanter for short paper pots) and a conventional one when they replace their harvester and transplanter. As a result, the following became clear. First, when a farm introduces new technology for self-sufficiently, the production cost will always exceed that of the conventional technology. Therefore, a contractor organization is required in order to reduce production costs by choosing new technologies. Second, when the farm continues to cultivate sugar beet in spite of lack of labor, it will be effective to introduce the new technology.
