本研究利用2001到2011年間的台灣出口貿易之縱橫資料，及加入關稅及實際匯率兩個變數之擴充型引力模型，來探討影響台灣資訊科技產品出口的關鍵因素。本研究實證結果顯示，進口國及出口國(台灣)之國內生產總值有顯著的正向影響；進出口國距離、關稅及實際匯率均有顯著的負向影響。也就是說，降低貿易關稅的確對台灣貿易出口有正向的影響；而實際匯率的實證結果則可看出，貶值並不是增進貿易出口適合的手段。

The study examines the determinants of Taiwan’s international exports of Information and Communication Technology (ICT) products to its 25 major trading partners using an augmented gravity model. We add two extra variables: the real exchange rate (RER) and the tariff. The former allows us to study the movement in the relative prices and their impact on trade pattern, the latter to analyze the impact of the tariff barriers on bilateral trade flows. The study first employs the Breusch-Pagan LM test, the Hausman test and the Hausman-Taylor over-identification test to choose the appropriate empirical method. The empirical result reveals that the lowing the tariff plays an important role in improving the exports of ICT products. In addition, the significantly negative coefficient of the real exchange rate implies that the currency depreciation strategy is not appropriate to the long-term bilateral trade in ICT products for Taiwan.
