Secondly, we choose the proportion of shares held by institutions as dependent variable, and we use log of the total asset, volatility, beta, Jensen Index, debt-to-asset ratio, dividend yield, turnover ratio, years listed in exchange and HS300 Index dummy as explanatory variables. Then we set up a multiple regression model. Finally, we use the cross-sectional data from the end of 2006 to the end of 2007Q3 to test the relationship between the explanatory variables and the proportion held by institutions.

具体方法如下：首先，在已有研究成果的基础上，对我国机构投资者的审慎性持股偏好提出了两个假设；其次，以机构持股占个股流通盘的比例为因变量，以公司的总资产对数值、波动率、贝塔值、Jensen指标、资产负债率、股息率、年度换手率、上市年限为解释变量，并在引入沪深300虚拟变量后，建立了多元线性回归模型；最后，采用我国证券市场迎来历史性大牛市、机构投资者发展最为迅猛的2006年末-2007年3季末的四个横截面数据，对各解释变量与机构持股比例之间的关系进行了实证检验。

Also the relative study on domestic economic problems with Markov switching model is very exility.

虽然，Markov机制转换模型及其扩展在宏观经济和金融等领域的应用取得了较大的成功，但由于该模型的参数估计比较困难以及相关检验方法存在一定的缺陷，从而导致其应用相对于一般的线性时间序列模型而言仍不够普遍，国内对Markov机制转换模型的相应研究则更为稀少。
