中国的基金自上个世纪末开始发展,近几年发展迅速。基金是否起到了稳定中国证券市场的作用?本文从基金对股票的持股比例与股票收益波动率之间的关系这一角度来分析基金的参与是否减小了我国股市的波动性。本文采用动态面板数据模型对1999年到2004年中国A股市场进行了分析,发现基金偏好收益波动大的股票,而另一方面随着基金提高其持股比例,其对应的股票收益的波动率减小,从而起到了一定的稳定股市的作用。
This paper applies dynamic panel data models to the stocks listed on Shanghai Stock Exchange and Shenzhen Stock Exchange from 1999 to 2004. We find that institutional investor prefer to the stocks with higher volatility, and on the other side, the increase in institutional holdings results in a decrease in subsequent volatility. Therefore, these institutional investments play a stable role in stock market.
