To clarify the difference between the impact of social-exchange and impression management motives on organizational citizenship behaviors (OCBs), this study selected leader-member exchange relationship to represent social-exchange motive, and ingratiation as the index of impression management motive. Moreover, based on the view of beneficiary-perspective of behavior, we categorized the targets of employees' organizational citizenship behaviors into job, organization, coworker and supervisor. Based on the questionnaires collected from managers, colleagues, and employees, we obtained 529 valid samples from administrative staffs working in Kaohsiung and Pingtung. The results showed that employees' ingratiatory motives only increased their OCBs toward supervisors, but had no effects on the targets of job, organization or coworker. Moreover, employees' ingratiatory motives had indirect effect on their OCBs toward other targets by increasing exchange relationships with their supervisors.
