This research takes self-identity as the research perspective, divides the situations of status consumption into self-identity promotion and threat, and tests the effects of self-identity promotion and self-identity threat on status consumption. Four experiments are designed in this study, Experiment 1 shows that both self-identity promotion and self-identity threat have positive effect to status consumption. Experiment 2 shows that self-identity promotion affects status consumption through the mediation of sustaining self-gift motivation. Experiment 3 shows that self-identity threat affects status consumption through the mediation of compensatory self-gift motivation. Experiment 4 reexamines the result with different participants and different materials.
