本研究以成立多年之某上市公司與某私立大學之基層員工為對象，採用問卷調查法蒐集資料，探討兩組織員工之組織政治知覺、信任、組織正義與組織公民行為是否存在差異，並驗證各變項間之關係。研究結果發現兩組織員工在各變項均存在顯著差異。研究結果發現：1.組織政治知覺之獨善其身構面，對信任、組織正義知覺及組織公民行為中之利他主義與公民美德呈負向影響；政策與實務落差構面則對主管信任及對組織正義知覺三個構面呈負向影響；同事自利行為構面對同事信任及組織公民行為之利他主義與運動家精神呈負向影響。2.組織正義知覺之分配正義知覺對主管信任呈正向影響；程序正義知覺對同事信任及主管信任呈正向影響；互動正義知覺則對同事信任、主管信任及組織公民行為之利他主義呈正向影響。3.同事信任對組織公民行為之利他主義與公民美德呈正向影響；主管信任對組織公民行為之運動家精神呈正向影響。研究亦發現同事信任分別對組織政治知覺、正義知覺與公民行為之關係具有中介效果；互動正義知覺則對組織政治知覺與公民行為之關係具有中介效果。 This research uses questionnaire survey to investigate the relationships among organizational politics perception, trust, organizational justice and organizational citizenship behavior.
