本研究以廻歸分析與階層線性模型等統計方法,檢測與驗證在個體層次中,員工的印象管理對其工作動機、工作績效是否具有正向之影響,並且工作動機在印象管理與工作績效之間,是否具有中介效果。此外,在總體層次中政治氣候對工作動機與工作績效是否有調節效果。本研究以石化工業為研究對象,並採用問卷調查法,參酌國內外學者之量表,經專家效度修改,進行預試發放,回收並測量信效度後,修改編製問卷,共發放1,200份問卷,回收後有效問卷共計1,077份。 經實徵研究後發現:(1) 整體上印象管理對工作動機具有預測力,人會使用各種策略來增強對自己的積極影響,以獲得有利的個人價值或物質結果;(2) 當個人所重視薪資及升遷,愈容易為薪資及升遷而努力工作時,其工作動機沒有顯著提升其工作績效表現;(3) 個人自覺的行為表現,引發了與工作有關的行為,並決定其強度、方向及持續時間,藉由主動表現其能力與成就來激發與工作績效相關的行為;(4) 藉由自願負責艱辛的工作或幫助同仁解決問題等行為,以達到彰顯自己能力與知識的機會,當員工的組織政治知覺較高時,則盡責對工作績效的影響愈強。
This study used statistical methods such as regression analysis and hierarchical linear modeling to examine and verify whether a positive correlation exists between impression management and the job motivation and job performance of individual employees, and whether job motivation has a mediating effect on the relationship between impression and job performance. In addition, whether overall political climate has any moderation effect on the relationship between job motivation and job performance was also examined. With the petrochemical industry as research subject, a questionnaire survey method was adopted. Scales used by domestic and international scholars were modified by experts for validity, and the pre-test administered. The returned questionnaires were measured for reliability and validity, and revised accordingly. A total of 1,200 copies were issued, and 1,077 valid questionnaires were collected. The study found that: (1) Overall impression management was predictive of job motivation. To achieve favorable personal or material outcome, individuals used different strategies to enhance their positive impact; (2)For individuals who value salary and promotion and are more likely to work hard for salary and promotion, their job motivation did not significantly improve their job performance; (3)When self-perceived conduct triggers work-related behaviors and determines their intensity, direction and duration, individuals actively demonstrate their abilities and achievements to motivate job performance related behaviors; and (4)For individuals who view actions such as volunteering for difficult work or helping their colleagues solve problems as opportunities for demonstrating their ability and knowledge, the higher their organizational political awareness, the greater the impact of due diligence on job performance
