发布时间:2019-04-25 12:11
【摘要】:笔者基于VAR模型和MGARCH模型,利用总量数据,对基金投资活动与我国股票市场波动性及其溢出效应进行实证研究。研究结果发现:基金的投资活动与股票市场波动之间存在双向影响机制,基金投资活动已开始对股票市场的波动形成影响,但基金没能起到稳定市场的作用;从波动溢出效应看,基金投资活动与股票市场波动存在双向的波动溢出效应,但溢出效应较小。
[Abstract]:Based on the VAR model and the MGARCH model, the author makes an empirical study on the relationship between fund investment activity and volatility and spillover effect of China's stock market by using the aggregate data. The results show that there is a two-way influence mechanism between the investment activities of the fund and the volatility of the stock market. The investment activities of the fund have begun to affect the volatility of the stock market, but the fund has not played a role in stabilizing the market. From the perspective of volatility spillover effect, there are two-way volatility spillover effect between fund investment activity and stock market fluctuation, but the spillover effect is relatively small.
