This study investigated the relationships among transformational leadership, subordinate-supervisor value congruence, person-organization value congruence, organizational identification and work group effectiveness. There was almost no research exploring this topic on military personnel's work attitude in Taiwan, so it is worth in-depth studying. This paper collected 298 valid samples from military personnel and used structural equation model to test the hypotheses established. The results confirmed that: transformational leadership positively influenced subordinate-supervisor value congruence, person-organization value congruence and organizational identification; subordinate-supervisor value congruence, person-organization value congruence all positively affected work group effectiveness.
