新疆棉花现货与期货市场价格动态关系的实证分析

The Empirical Analysis of the Dynamic Relationship between Cotton Spot and the Prices of the Futures Market in Xinjiang

为探讨新疆棉花期货上市以来棉花期货价格与现货市场价格的相互引导关系,采用ADF检验、协整分析和Granger因果检验等计量经济学方法,分析了新疆棉花现货和期货市场价格走势和影响的因果关系。结果表明,新疆棉花现货市场价格与期货市场价格短期波动明显,长期趋向均衡;棉花期货市场对新疆棉花现货市场价格有明显的引导作用,而新疆棉花现货市场价格对期货市场价格影响不大。政府应继续完善新疆棉花期货市场建设,使其价格发现功能和套期保值功能得以发挥,以此来促进新疆棉花产业的发展。
