Abstract
本研究在近9,000 家的糧商中，利用立意抽樣，篩選出37 家主要廠商，針對其民間稻米庫存進行調查。經由本調查發現，102 年12 月底，其庫存稻穀為100,792.40 公噸。同期間，其稻穀進貨量為251,105.90 公噸，占民間進貨量的21.22%。假設民間其餘廠商的平均存貨行為與樣本廠商相似，則可推估全體廠商的稻穀數量為474,986.31公噸。同時，本研究刪除不合理樣本後，所餘樣本約22–24 個，所推估的結果差異並不大，因此，顯示本研究的樣本選擇應具備一定的代表性。此一抽樣調查方式將有效降低國內稻米民間存糧的調查成本。
This research aims at investigating the available stock of rice in the private sector. Of all 9000 food dealers, 37 main dealers are selected by purposively sampling. This research found that the available stock of rice, to the end of December in 2013, is 100,792.40 tons; meanwhile, the purchase volume of rice is 251,105.90 tons, accounting for 21.22% of private sector purchase volume. Suppose that the average inventory levels of other private dealers are similar to the sampling dealers, we suggest the overall stock of rice be 474,986.31 tons. The estimated inventory levels of the remaining other 22 to 24 sampling dealers, on the premise of omitting outliers, do not show great discrepancy from purposive samples. The sampling selection of this study, therefore, can make sufficient inference about the popularity. The survey cost on domestic inventory level of rice will greatly reduce through this sampling method.
