基于面板数据研究了股票流动性水平、流动性风险与股票收益率之间的关系。研究得到:①包含控制变量的混合截面回归分析结果表明,流动性水平越高收益率越低,即我国股市中存在流动性溢价效应,流动性变化率是影响股票收益率的重要因素。②基于固定效应VAR的因果检验表明,流动性变化率与收益率之间存在双向的因果关系。
We study the relationship among liquidity level,liquidity risk and stock's return by use of panel data.The result are:(1) The pooled crossing regression with control variables,the coefficient of liquidity level is notably negative,there is a liquidity premium in Chinese stock market;the change of liquidity has some influence on the return.(2) We construct a VAR model to study the causal relationship among them,and find that there is a bi-directional causality between the change of liquidity and the stock's return.
