摘要：股指期货已经成为证券市场上一个重要的交易工具。随着股指期货在我国的推出，我国的证券市场也产生了一定程度的波动。

　　　本文试图分析股指期货的推出对我国证券市场波动的影响。选取了沪深300股指期货作为研究对象，利用股指期货推出前后日交易数据来建立模型，进行实证分析，得出沪深300股指期货的推出减轻了我国证券市场的波动。本文的创新之处就在于沪深300股指期货在我国推出才仅有一年的时间，国内外对沪深300股指期货的实例研究还比较少，本文的研究能够为我国股指期货的发展提供一定的政策性建议，有一定的研究意义。但是，由于沪深300股指期货推出的时间还比较短，本文未能够对沪深300股指期货的推出对我国证券市场的影响做更为深入的分析，这也是本文需要改进和提升的地方。
