In this paper, we examine the effect of the production adjustment and the shipment adjustment according to the usage of the mandarin orange by using the conjectural variation model. The result are follows. The production adjustment and the shipment adjustment according to the usage are worked by the producer group.　Of them, the latter is tried to maximize the revenues in the market of the mandarin orange to be eaten raw. Therefore, it is requested to keep planned quantities in the market of the mandarin orange to be eaten raw but is not in the market of it for processing. By calculating the constant imperfect competitive (λr＝0.2) for years, it becomes evident that the shipment adjustment operates quasi effectively because of such an adjustment method. Meanwhile the market price falls below the marginal cost recently in the market for processing, so the imperfect competitive is calculated as minus. In fact, it becomes evident that the mandarin orange is dumped to keep the revenue in the market to be eaten raw. For this reason, it is suggested to tighten the production adjustment and to decrease the mandarin orange for processing.
