摘要
根据所构建的双变量EC-EGARCH模型,对我国大豆期货与现货市场之间的波动溢出效应进行实证分析的结果表明:协整残差项对期货与现货市场的条件均值和条件方差均具有很好的解释作用,能够准确地刻画两市场之间的波动性关系;期货和现货价格之间存在长期的均衡关系;并且,期货与现货市场之间的波动溢出效应是对称的。
The volatility relationship in China's spot-futures markets are investigated empirically based on the bivariate EC-EGARCH model.The empirical results show that the co-integrating residual can be an important explanatory variable for both the conditional mean and the conditional variance and can describe the volatility accurately in spot-futures markets.And there is a longrun equilibrium relationship in spot-futures prices and a symmetrical spillover in volatilities of spot-futures markets.In addition,the countermeasures and suggestion are given according to the practical situation of China's soybean futures market.
