本文以台灣地區小客車輻射層輪胎產品為研究對象,進行匯率與出口單位收入的關係之實證研究。資料期間為2000年至2008年間對20國出口之年統計資料。實證估計分別依國家別、產品價位別、市場穩定性、市場規模四個方向進行分析。估計結果顯示,隨著匯率變動,出口廠商會以市場穩定程度與否以及市場規模兩者作為產品定價的主要考量因素。此外,廠商往往利用台幣貶值之機會,藉由降低出口價格來提高國際競爭力或擴大市場佔有率。 This thesis empirical studies the pricing to market behaviors of the export prices of Taiwan made radial tires for passenger cars.
