【摘要】:自我國(guó)匯率制度改革實(shí)施以來,人民幣匯率的走勢(shì)便受到國(guó)內(nèi)外學(xué)者的廣泛關(guān)注,我們以石油價(jià)格沖擊為主線,研究石油價(jià)格沖擊對(duì)人民幣匯率波動(dòng)的影響。利用平滑轉(zhuǎn)換回歸(STR)模型,對(duì)2006年1月至2015年12月石油價(jià)格和人民幣匯率的關(guān)系進(jìn)行研究,研究結(jié)果表明:石油價(jià)格是人民幣名義匯率變化的Granger原因,反之不成立;石油價(jià)格對(duì)人民幣匯率的沖擊具有非對(duì)稱性,當(dāng)石油價(jià)格負(fù)向變化率低于閾值水平或正向變化時(shí),石油價(jià)格波動(dòng)對(duì)人民幣匯率的影響程度較小;當(dāng)石油價(jià)格負(fù)向變化率高于閾值水平時(shí),石油價(jià)格波動(dòng)對(duì)人民幣匯率的影響程度較大;當(dāng)石油價(jià)格處于閾值水平附近時(shí),石油價(jià)格波動(dòng)對(duì)人民幣匯率的影響將在兩個(gè)機(jī)制之間平滑轉(zhuǎn)換,并且轉(zhuǎn)換速度非常快。
[Abstract]:Since the implementation of China's exchange rate system reform, the trend of RMB exchange rate has received extensive attention from domestic and foreign scholars. We study the impact of oil price shock on RMB exchange rate fluctuation with oil price shock as the main line. The relationship between oil price and RMB exchange rate from January 2006 to December 2015 is studied by using smooth transformation regression model. The results show that oil price is the Granger cause of the change of RMB nominal exchange rate, otherwise it does not hold true. The impact of oil price on RMB exchange rate is asymmetric. When the negative change rate of oil price is lower than threshold level or positive change, the impact of oil price fluctuation on RMB exchange rate is small. When the negative change rate of oil price is higher than the threshold level, the fluctuation of oil price has a great influence on the RMB exchange rate, and when the oil price is near the threshold level, The impact of oil price fluctuations on the exchange rate of the yuan will be smoothly converted between the two mechanisms, and the rate of conversion will be very fast.
