摘要

Adrian and Franzoni (2009) gives the conditions CAPM model for learning expand,this paper made state space model,provide 25 divided portfolios by Size,B/M,the Kalman filter results indicate that the estimated results of time-varying Beta better fit the stock price volatility then OLS estimated,Beta factor is learning process,in the Chinese stock market,the B/M is more significant than the Size into the learning process,the effect of the Size factor is not significant.
