Note: Absolute value of t statistics in parentheses * significant at 5%; ** significant at 1% Each column presents a separate ordinary least squares (OLS) regression, with the dependent variable as listed in the column heading and the explanatory variables as listed in the first column; each cell of the table reports the estimated regression coefficient, with the absolute value of the associated t statistic in parentheses below the estimated coefficient. We take the natural logarithm of each dependent variable e.g., ln (value of assets in 10,000 RMB) and use that converted form for the econometric analysis to avoid an artificial bias in the statistical results from the skewed distribution of the continuous dependent variables.
