摘要
选取中国全部六个交割月份棉花期货合约价格和中国棉花3128B价格指数作为研究对象,构建OLS,B-VAR,ECM和ECM-BGARCH四种模型来估算最优套期保值比率,并应用Ederington法评估套期保值的效率,分析中国棉花期货最佳的套保模型。结果表明,1月、5月、11月份合约的套期保值都能在一定程度上规避价格风险,其中OLS和B-VAR模型的效果最好,最后提出完善期货市场的建议。
Selecting the total six delivery months China's cotton futures price and the CC Index3128B as the research objects,four models of OLS,B-VAR,ECM and ECM-BGARCH are constructed to estimate the optimal hedging ratio,and the Ederington method is used to evaluate the hedging efficiency,and analyze the best hedging model for China's cotton futures on the hedging efficiency.The results show that the hedging of January,May,and November contracts can avoid price risk.Among them,the OLS and B-VAR models have the best hedging efficiency.Finally,suggestions for perfecting the futures market are put forward.
