英文摘要：

This paper studies, the relations between stock spot price and futures price by empirical mode with the technique of cointegration and VAR. It mainly consists of cointegrational relation which reflects long-term equilibria relation between stock spot price and futures price, Grangerian causality and some tests such as ADF unit root test,cointegration test and cointegrational Grangerian causality. In additon, some metric results are presented.
