本研究針對領導成員交換關係差異性對組織結果有正面或負面的影響尚未有一致結果此議題討論。本研究以某大型商業銀行之23間分行計228組主管與部屬資料配對樣本，結果顯示領導成員交換關係差異性對於團隊凝聚力具有顯著負向影響，進而降低團隊創造力。研究亦顯示非績效基礎關係差異性會加深領導成員交換關係差異性對團隊凝聚力的傷害。非績效基礎關係差異性扮演著負面調節的角色，團隊凝聚力為正面調節的角色。

In this paper, we aim at analyzing the inconclusive results of leader-member exchange (LMX) differentiation. Data from 228 supervisor-subordinate dyads in 23 branches of a large Taiwanese bank provided concrete evidence that LMX differentiation was negatively related to team cohesion and that the quality of team cohesion mediated the negative effect of LMX differentiation on workgroup creativity. Moreover, the relationship between the LMX quality and employee creativity was positively moderated by team cohesion and negatively moderated by non-performance-based LMX differentiation. We also find out negative relationship between LMX differentiation and team cohesion was moderated by nonperformance- based LMX differentiation.
