This paper examines empirically what factors affect the internal use of Performance Information (PI) in South Korean public agencies. In order to do this, this paper has identified dimensions of the internal use of PI and examined the role of institutional, individual, data quality, and external factors to be correlated with the internal use of PI. Data from 333 public managers from four different South Korean public agencies participating in the survey were used to test the relationship. The results show that public officials’ use of PI for managerial and organizational decision making is affected by several factors. Particularly, individual perception about Performance Management (PM) have significant relationships with the internal use of PI (both managerial and organizational use), suggesting that the individual-level factors may results in differences in the uses of PI. However, this study highlights that different factors have affect the different use of PI. On the one hand, institutional factors (the quality of PMS and gatekeeping), group and development culture, and role of stakeholder have significant relationship with managerial use. On the other hand, data quality, rational culture, and grade is significantly and positively related to organizational use of PI. This result implies that PMS should be carefully constructed and implemented, in order to enlarge the use of PI for the internal decision making. It is needless to say that purposes of PI use should be considered.
