摘要

This article analyzed the index systems of finance in listed company annals with the method of multiple linear regression analysis. It took earnings per share as explained variable, the rest as the explanatory variable. It got rid of the extraordinary values and strong effect dots through Centered Leverage Value and Cook's Distance etc. It tested Residual normal distribution, equal variance,independence, the linear relationship between dependent and independent variables. It eliminated multicollinearity gradually among independent variable. At last, we obtained a multiple linear regression equation including a constant about earnings per share with 8 explained variables and a regression equation of standardized coefficients which eliminate the impact of dimension. It can be used in quantitative analysis and qualitative analysis with this multiple linear regression equation, and it also can be used in economic forecasting and economic analyzing.
