摘要


西元2002年1月1日台灣正式成為世界貿易組織(WTO)會員,貿易自由化對國內農業造成莫大的衝擊。本研究試圖針對我國近年來農藝產品進出口量之變化進行統計分析,藉此瞭解我國在加入WTO後對各農藝產品進出口量所造成之影響。 本研究主要針對四大類別農藝產品,係穀類、中草藥及刺激性作物(如菸草、咖啡與茶葉等)及其他作物。資料來源為行政院農業委員會所屬之「農產貿易統計查詢系統」,該系統係行政院農業委員會委託財團法人資訊工業策進會,根據財政部海關進出口資料彙整而成。另一方面為確保可得之研究資料為最新的,資料蒐集至西元2005年12月31日止。因此,本研究分以48組月進口量與月出口量來進行統計分析(西元1998年1月至2005年12月,組別分界為WTO前後各四年),藉由敘述統計中之平均數與標準差來分析資料。此外,透過配對t檢定(Paired t-test)、Cox-Stuart檢定法、時間序列(Time Series)之介入模型(Intervention Model)檢定法,分析進出口量在WTO前後是否有所衝擊。 研究結果發現,自西元1998年1月至2001年12月稻米總進口量由22,751.76公噸增加至460,354.77公噸。20倍之進口稻米量增加呈現顯著之差異(p-value < 0.0001)。除此之外,結果發現WTO亦導致下列其他農藝產品顯著之影響:(1)進口量:包含麵食、麥芽精、檀香木碎片、胡椒、咖啡、茶葉、菸製品、葡萄糖及葡萄糖漿等,在進口方面有顯著之增加。(2)出口量:包含小麥、吉林人蔘、茶葉與酒類等,在出口方面有顯著之增加。 總結本研究分析,說明了台灣在加入WTO之後確實有部分農藝產品在進口與出口呈現顯著之改變。最後,希望透過本研究能有助於政府相關單位,在面臨WTO衝擊下之挑戰,能做出最適政策。

After Taiwan formally joined the World Trade Organization (WTO) in January 1, 2002, free trade may make a great impact on domestic agriculture. We undertake statistical analyses on the changes of the export and import amount for agronomy products in recent years and attempts to investigate the effects of WTO on the agronomy products. Three types of agronomy products are considered; cereal, Chinese herbal medicine, and others including tobacco, coffee, tea, etc. Data are obtained from the public accessible website of Agricultural Trade Searching System of The Council of Agriculture, Taiwan who authorizes the Institute for Information Industry to collect the information of export and import amounts from the Custom Service, Department of Finance, Taiwan. To ensure that the latest available information, the cutoff date is set to be December 31, 2005. Therefore, 48 pairs of monthly export and import data from January of 1998 to December of 2005 are available for statistical analyses. Descriptive statistics such as mean and standard deviation are used to summarize the data. Paired t-test, Cox-Stuart test, and Intervention Model of Time Series are employed to empirically examine the impact of WTO on import and export of agronomy products in Taiwan. Results show that from January of 1998 to December of 2001, total import amount of rice is 22,751.76 metric tons and total import amount is 460,354.77 metric tons. This 20-fold increase of import of rice is statistically significant (p-value < 0.0001). In addition, the results show that WTO even causes the significant influence on the following agricultural products: other crops with statistically significant increase of import including wheaten food, malt, chip of the sandalwood, pepper, coffee, tea, tobacco products, glucose and glucose thick liquid. Agronomy products with statistically significant increase in export amount are wheat, Jilin ginseng, tea, and wine. Our analyses demonstrate that statistically significant changes in import and export occur after Taiwan joined the WTO in some of agronomy products. It is suggested that our government should set up appropriate policies in encountering this challenge.
