摘要

本研究以跨層次研究之觀點，主旨以政治技能對工作績效的影響為主軸，並以主管與部屬交換關係為中介變項及主管部屬交換關係差異性為干擾變項，探討政治技能、主管與部屬交換關係、主管部屬交換關係差異性與工作績效之跨層次關係。本研究以一家中日合資公司為研究對象，從主管與部屬兩個來源來蒐集樣本，共計發放25組，合計140人完成問卷填答。經配對確認及刪除不完整之問卷，共回收124份有效配對資料，有效回收率88%。本研究以層級線性迴歸分析進行研究假設之驗證。研究結果發現：在個體層次方面，成員政治技能對成員績效有正向關係；成員政治技能對主管與部屬交換關係有正向關係；主管與部屬交換關係對成員政治技能和成員績效兩者間具有中介效果。而在群體層次方面，主管部屬交換關係差異性的確為主管與部屬交換關係與成員績效間的干擾變項。此結果意味著，當團隊處在主管部屬交換關係差異性愈高的環境時，主管與部屬交換關係和團隊成員的工作績效之間的影響會越強。

We adopted a cross-level study to analyze the relationships among political skill, leader-member exchange (LMX), leader-member exchange differentiation (LMXD) and job performance. We proposed that LMX serves as a mediating mechanism through which political skill affects employee job performance. We further argued that the modeled relationship is moderated by LMXD. Data were collected from multiple sources, supervisors and subordinates, comprised 140 employees in a Taiwan-Japanese joint venture company. Hierarchical linear modeling analysis (HLM) was employed to test the proposed hypotheses. Our results indicated that political skill is positively related to job performance and LMX at individual-level. LMX mediates between political skill and job performance. At group-level, LMXD moderates the relationship between LMX and job performance. The results revealed that with higher LMXD, the impact of LMX toward job performance will be stronger. The study provides preliminary evidence of the mediation effect of LMX and the moderating effect of LMXD in the relationship between political skill and job performance.
