结果表明:交易量与收益率波动的关系是正相关,持仓量与收益率波动之间的关系是负相关;将交易量、持仓量分割为预期和未预期两部分,发现未预期部分对收益率波动有更大的影响,且未预期部分本身的正、负变动对收益率波动的作用程度是不对称的;大的持仓量能减缓收益率波动。

由于我国期货市场不是很成熟，我用已有的模型对中国及国外的期货市场的收益，收益波动进行了详细的实证检验，通过与国外期货市场的比较看出我国期货市场相对不成熟的具体地方，为了能在我国仅有的期货信息上找出我国期货市场中具体不成熟的隐性原因，我对原有的模型进行了修改，并结合国内外期货数据再次进行实证检验，得出期货市场中的收益还与日期货市场指数有关，交易量变大会增加收益波动，持仓量有助于减小波动，无预期交易量，无预期持仓量对波动影响大于预期交易量，预期持仓量对波动的影响，结合原来前人的结论与本文得到的结论针对我国不同交易所指出了它们存在的具体问题，之后在我国现有基础上提出了解决问题的具体方法。
