本研究旨在探討如何有效促進組織成員間的互助、合作及知識分享,以強化企業的競爭優勢,並以人際脈絡績效為依變項,劃分為人際公民行為及知識分享行為等兩構面,試圖找出其影響的因素。由於人際脈絡績效並不像「任務績效」那般易於衡量及誘發,而係屬自發性產生的利他人、利組織、利社會的角色外行為,組織較難透過正式控制與激勵制度予以誘發。經文獻回顧及整理後,本研究認為職場上互動的兩人間是否具特性相似性及建立良好關係品質,會是影響雙方互助行為的重要因素,故將知識工作者的對偶同質性作為人際脈絡績效的前因變項,並探討關係品質是否具中介的效果。由於本研究採對偶且記名方式蒐集資料,極需要受訪對象的高度配合,故須採研究者親自前往受訪公司發放及當場回收問卷,經過一番努力,幸運獲得十七公司接受訪查,總共發放了645份問卷,回收有效問卷505份,有效回收率為78.3%。經統計分析後發現,當兩位同事互為異性、學歷及年資愈相近時,有助於強化兩人的強連帶關係及人際公民行為,對人際信任及知識分享行為的影響效果則不顯著;主觀價值觀契合度對人際公民行為及知識分享行為皆有正向影響,而關係品質中的強連帶關係及人際信任則確實在其中扮演中介的效果,由此可知同事問的人際互動行為,確實會受到相似吸引的效果影響,此研究結果可作為人力資源管理實務上,人員招募、工作配置及團隊成員遴選等決策時的參考之用。
In order to enhance the competitive advantage of organizations and also attracting and maintaining rare knowledge workers, the promoting of the cooperative and knowledge sharing behavior between knowledge workers has become an increasingly important topic for both the practitioners and researchers. In contrast to the job/task performance, contextual performance is a sort of altruistic, pro-social behavior difficult to measure and motivate by formal control and incentive system. In order to explore the determinative factors of 'Interpersonal Contextual Performance, ICP' which represent the interpersonal dimensions of contextual performance, we draw on similarity/attraction paradigm, self-categorization, and self-identity as the theory basis of dyadic homophily, which functions as the antecedents of ICP We also draw on 'relationship quality' as a mediating factor between 'dyadic homophily' and ICP to create an integrated model. This study collected 505 valid samples from 17 organizations. The results show positive effect of 'dyadic homophily' on 'Interpersonal Contextual Performance' and the mediating effect of relationship quality on them. Two inter-actors with opposite sex, similar education level and tenure have stronger ties and inter-personal citizenship behaviors. The positive effects of subjective value congruence on relationship quality and interpersonal contextual performance are also verified. Our findings may have practical implication for human resource practitioners who recognize the importance of developing better relationship quality as a means of enhancing employees' contextual performance.
