摘　　要：流动性是决定资产收益的重要变量之一,笔者主要通过数据的实证检验,验证市场流动性是否能完全解释流动性溢价,构建一个包含了Fama-French模型三因素和市场流动性因子的四因素模型,并利用上海证券交易所上市公司数据进行时间序列和面板数据分析,实证结果都支持了股票预期收益与流动性的强相关性。其中在时间序列检验中,从低流动性到高流动性资产组合中,两个模型的截距项都逐渐降低;进一步的GRS检验表明两个模型的截距都不同时显著为0,这都说明市场流动性因素不能完全涵盖个股流动性水平。Liquidity is one of the important factors deciding returns on assets. Through an empirical test with data, the authors verified whether market liquidity can explain fluid premium completely, constructed a four-factor model including the three factors of Fama- French and the factor of market liquidity. The authors also made a time series and panel data analysis with the data of the listed compa- nies in Shanghai Stock Market. The empirical results support the correlation between the prospective earnings of stocks and liquidity. In the time series test, in the asset portfolio from low liquidity to high liquidity, the intercept items of both models gradually reduce; fur- ther GRS test indicates that the intercept of neither models shows to be zero, which explained the market liquidity factors cannot cover the stock liquidity factor completely. Future researches should seek better unified asset pricing model to hold the influence of all liquid- ity characteristics on the earnings of assets.
