摘要


本研究以縱橫平滑移轉迴歸模型(Panel Smooth Transition Regression, PSTR model)探討利率與物價變化對出口匯率轉嫁程度依時變動(time-varying)的門檻效果(Threshold effect)。文中以利率與消費者物價指數年增率作為轉換變數,台灣出口貿易前十一大出口貿易國為對象,樣本區間自1994年至2013,共計220筆觀察值。實證結果可提供出口商採取有效的出口財訂價策略,以及政府單位有效的提振出口貿易之貨幣政策之參考。 實證結果歸納如下: 一、 匯率轉嫁程度依時間與國家的不同而改變,亦即隨各國在不同時期的轉換變數(利率與消費者物價年增率)的變化,其匯率轉嫁程度不同。 二、 在以利率為轉換變數的PSTR模型下,出口物價指數呈現非線性且非對稱的平滑轉換過程,其利率水準介於兩個門檻值之間時,匯率轉嫁程度最大。匯率轉嫁程度隨利率水準的提升,呈現先增加而下降的變化。 三、 以消費者物價指數(CPI)年增率為轉換變數的PSTR模型下,出口物價指數亦呈現非線性,卻為對稱的平滑轉換過程。匯率轉嫁程度隨CPI年增率增加,呈現先上升至高點後下降的對稱平滑轉換的型態。換言之,整體物價上升時,匯率轉嫁程度亦上升,而在高度通貨膨脹下,匯率轉嫁程度則下降。  四、 代表出口商邊際成本的躉售物價指數年增率,對於出口價格的影響,無論在高通貨膨脹或低通貨膨脹下均不顯著,亦即出口商邊際成本對於出口財訂價的衝擊並不明顯。

This study uses the panel smooth transition regression (PSTR) model to evaluate the time-varying and threshold effects of interest rate and the change in consumer price index (CPI) on export exchange rate pass-through. In the PSTR models, the transition variables are interest rate and the change of CPI. The sample objects are Taiwan’s Top 11 export partners, and sample period spans from 1994 to 2013. Thus, there have 220 observations. The empirical results provide crucial information for exports to adopt effective export pricing strategies and for monetary authorities to apply appropriate trade policies to stimulate export. The key empirical results can be summarized as follows: 1. The exchange rate pass-through (ERPT) varies with time and across countries, i.e., depending on individual trade partners’ interest rates and CPI change in different regimes. 2. In the PSTR model with interest rate as the transition variable, the ERPT is maximum as interest rate locates between two threshold values, That is, the ERPT display a trend of rise first then fall. 3. In the PSTR model with the change in CPI as the transition variable, export price level has a symmetric and smooth transition process, and the ERPT also displays a trend of rise first then fall. 4. The marginal cost , measured by wholesale price level, of exports has an insignificant effect on export price index at any level of change rates in CPI. That is, the wholesale price level has an insignificant impact on pricing strategy of export goods. Keywords: exchange rate pass-through; consumer price level; cost mark-up; panel smooth transition regression model.
