<p>This study explores proactive administration in South Korea not only from legal and institutional perspectives but also from the viewpoint of achieving the public interest through collaborative relationships with citizens. In addition, it examines how job-related factors—job clarity, autonomy, job resources, and job competency—are associated with proactive administration. The findings indicate that all job-related factors are positively related to proactive administration; however, these effects vary by rank. Based on these findings, the study provides both theoretical and practical implications, contributing to empirical research on the expanded concept of proactive administration.</p>
