摘要
以中国的大豆、玉米和小麦的期货和现货价格为研究对象,运用多重分形非对称去趋势交互相关分析(MF-ADCCA)和多元多重分形去趋势交互相关分析(MV-MFDCCA)等多重分形分析方法探讨了中国粮食期货与现货市场之间交互关系的多重分形特征.实证结果表明,中国粮食期货与现货间的交互相关关系具有多重分形和非对称性特征,且粮食期货与现货间的交互关系的非对称性程度在不同的波动情形下存在差异.此外,粮食期货与现货系统之间的交互相关关系是多重分形的,且两个市场间的整体风险传染效应较弱.
Taking the futures and spot prices of soybeans,corn and wheat in China as the research object,this paper applies the multifractal analysis methods including MF-ADCCA and MV-MFDCCA to explores the multifractal characteristics of cross-correlations between grain futures and spot markets in China.The empirical results show that the cross-correlations between grain futures and spot in China have multifractal and asymmetric characteristics,and the asymmetry degree of cross-correlations between grain futures and spot are distinct under different fluctuations.In addition,the cross-correlations between grain futures and spot systems in China are multifractal,and the overall risk contagion effect between the two markets is relatively weak.
