摘要 本文选取2008年1月9日至2010年12月31日之间期货价格和现货价格数据,运用传统回归模型(OLS)、双变量向量自回归模型(B-VAR)、误差修正套期保值模型(ECM)、误差修正GARCH模型(EC-GARCH)对样本数据进行平稳性和协整关系检验,在估计最小风险套期保值比率的基础上发现:(1)我国黄金期货市场运行三年多来,通过黄金期货市场进行套期保值是有效的,可以较为明显地降低参与者面临的价格波动风险;(2)在具体进行套期保值操作时,应该根据套期保值时限长短的不同和预期效果的差异,采用不同的模型来合理确定自身的套期保值比例。在此基础上,本文提出了相关政策建议。 Based on the data of futures prices and spot prices trom January 9, 2008 to December41, 2010, the paper uses traditional regression model (OLS), two-variable vector auto regression model (B-VAR), error correction model (ECM) and error correction GARCH model (EC- GARCH). Results show that.. (1) hedging through the gold futures contracts is effective, which can significantly reduce the participants' risk of price fluctuation; (2)hedging ratio should be determined by different models according to the length of time and different expectations. The paper also made some proposals based on the conclusions.
