This paper investigated the effect of birthplace against the perceived risk (performance risk, psychological risk and social risk) and financial behavior (saving behavior and investment behavior) through samples differentiated. We presented results from 333 residents of Kinmen County and tested two scares with confirmatory factor analysis, correlation analysis, variance analysis, and regression analysis were performed to examine hypotheses. We observed that (1) perceived risk (performance risk and social risk) had significant positive effect on financial behavior (saving behavior and investment behavior) and (2) birthplace had a moderating effect on the relationship between perceived risk and financial behavior.
