机构持股对房地产股票收益波动的影响研究基于面板数据的门限分位回归模型∗

摘要

For the problem of correlation between institutional ownership and the volatility of real es-tate companies stock returns in different market conditions,this paper establishes a threshold quantile re-gression model with panel data.We confirm that in different market conditions,for the real estate compa-nies whose stock returns volatility is at different levels,there are differences in the effect degree of institu-tional ownership.If the stock market appears extreme returns,institutional ownership strengthens the stock returns volatility.The positive impacts of institutional ownership increase with the quantiles of the volatility when the stock market extremely falls.In the whole consolidation market,the proportion of in-stitutional ownership does not have a significant impact on stock returns volatility,but the change of pro-portion will weaken the stock returns volatility.%针对在不同的股市行情中机构持股与房地产公司股票收益波动之间的相关性问题，建立面板数据的门限分位回归模型进行检验。证实在不同的市场行情中，对于股票收益波动处于不同水平的房地产公司，机构持股的影响程度存在差异。当股市大盘出现极端情形，机构投资者加剧股市波动。大盘大跌，机构持股的促进作用随着股票收益波动的分位点的增大而增强。在盘整市，机构持股比例没有对股票收益波动产生显著影响，但其变动抑制股票收益波动。
