摘要
利用动态经济计量学方法对上海期货交易所(SHFE)与伦敦金属交易所(LME)的期铜价格走势进行的实证分析说明,在统计区间内SHFE期铜与LME期铜价格间存在着协整关系,LME期铜和SHFE期铜价格间存在双向G range成因,来自于SHFE的标准差冲击对SHFE和LME期铜价格的作用都有持续性,而对来自于LME的标准差冲击,SHFE有着过度的反应。
With the method of dynamic econometrics, this paper analyzes the relationship between the price of LME copper and the price of SHFE copper. The result shows that the price of SHFE copper is cointegrated with the price of LME copper, the price of LME copper is the Granger cause of the price of SHFE copper and the price of SHFE copper is the Granger cause of the price of LME copper too. An impulse from SHFE standard error has some influence on both SHFE and LME copper price, while SHFE copper price has some excess response to an impulse from LME standard error.
