| Against 45-degree line | – | – | – | – | ||||
| Against Lorenz Curve | None | + | ||||||
Note:(1) *P < 0.05, **P < 0.01; (2) Statistically significant differences (P < 0.05) were found in all values of CIs between 2008 and 2013 using the z-test. (3) - indicates the 45-degree line/Lorenz curve dominates the concentration curve; + indicates concentration curve dominates 45-degree line/Lorenz curve; none indicates non-dominance; a blank space indicates that the variable is not applicable
