Methods 5927 citizens from different cities were assessed by NEO five-factor inventory(NEO-FFI)and satisfaction with life scale(SWLS). Results (1)The mean score of life satisfaction was 19.61±5.99.Female scored higher than male, and there were statistically significant differences between them(19.98±5.92 vs 19.14±5.95, t=-5.08, P<0.01). (2)The absolute income, extraversion and conscientiousness had a significant main effect on life satisfaction(β=0.13~0.19, P<0.01), neuroticism, openness and agreeableness had a significant main negative effect on life satisfaction(β=-0.04--0.15, P<0.01). (3)The relative income had a significant main effect on life satisfaction(β=0.35, P<0.01). (4)Relative income had a mediating effect on the relation between absolute income, neuroticism, extraversion, agreeableness, conscientiousness and life satisfaction(P<0.01). Conclusion Relative income has a mediating effect on the relation between absolute income, personality and life satisfaction.
