Abstract: Online community provides a continual social platform for the vast floating population. On this platform, consumers establish their public images by sharing information, whereby they can perform impression management and achieve their identity. From the perspective of socioecological psychology, this paper explores the joint effect of residential mobility and numerical source status upon information sharing intention, as well as its mechanism and boundary condition. Across four experiments ,this research shows that: ( 1) Residential mobility and numerical source status jointly affect consumers' information sharing intentions. Specifically, individuals with high residential mobility matched with minority source status, will have higher information sharing intention. Meanwhile, individuals with low residential mobility matched with majority source status, will have higher information sharing intention. (2) Perceived uniqueness, not social bonding motivation or self-esteem instability , mediates this joint effect mentioned above. (3) Implicit theories of personality moderate the joint effect of residential mobility and numerical source status on information sharing intention.

Key words: residential mobility , information sharing intention , numerical source status , perceived uniqueness , implicit theories of personality
