以美国西德克萨斯轻质原油现货价格(WTI)、英国北海布伦特原油现货价格(Brent)、中东迪拜原油现货价格(Dubai)和中国大庆原油现货价格(Daq)为代表性的研究对象,运用耦合消除趋势波动分析法(CDFA)对国内外原油市场之间耦合关系的多重分形特征进行实证分析。实证结果表明:原油市场之间的耦合关系具有明显的多重分形特征;厚尾分布和长记忆性是产生多重分形特征的主要原因;无论就长记忆性而言,还是就厚尾分布而言,WTI 对原油市场耦合关系多重分形特征的影响最为突出。
以美國西德剋薩斯輕質原油現貨價格(WTI)、英國北海佈倫特原油現貨價格(Brent)、中東迪拜原油現貨價格(Dubai)和中國大慶原油現貨價格(Daq)為代錶性的研究對象,運用耦閤消除趨勢波動分析法(CDFA)對國內外原油市場之間耦閤關繫的多重分形特徵進行實證分析。實證結果錶明:原油市場之間的耦閤關繫具有明顯的多重分形特徵;厚尾分佈和長記憶性是產生多重分形特徵的主要原因;無論就長記憶性而言,還是就厚尾分佈而言,WTI 對原油市場耦閤關繫多重分形特徵的影響最為突齣。

Coupling Detrended Fluctuation Analysis (CDFA)is used to analyze the multifractal characteristic of coupling relationship between domestic and international crude oil markets,which draw upon WTI,Brent and Dubai crude oil spot prices typical of international crude oil markets and Chinese Daqing crude oil spot prices (Daq)typical of domestic crude oil markets. The empirical results demonstrate that the coupling relationship between four crude oil markets are multifractal and main reasons for the multifractal characteristic are heavy tailed distribution and long memory;for both long memory and heavy tailed distribution,WTI has a significant influence on multifractal property of coupling relationship in crude oil markets.
