企業社會責任(corporate social responsibility，簡稱CSR)的概念與實務發展在近年來已成為一門企業永續經營的顯學。本研究認為，有別於一般組織外部利害關係人的觀點，身為內部觀察者的員工身分具有特殊性，不僅較外部利害關係人更接近公司核心，亦有機會參與公司的企業社會責任政策制定與活動。因此，本研究旨在建構一研究模型，以員工觀點了解企業社會責任認知及企業志工參與對組織公民行為之影響過程與結果，包含探究員工對企業社會責任認知與企業志工參與程度是否與組織認同有正向影響？員工企業社會責任認知與組織認同是否為知覺外部聲望所中介？當員工組織認同提高時，是否增進其工作滿足、組織承諾、顧客導向？ 　　本研究以Kim et al.(2010)所提出的企業社會責任影響員工企業認同模型概念為基礎，並拓展員工可能展現的反應及工作態度構念，以便利抽樣法回收有效紙本問卷201份、有效網路問卷115份，共計獲得316份樣本。經由驗證性因素分析與結構方程模式(Structural Equation Modeling, SEM)分析後得出研究結論如下： 1.知覺外部聲望確實為企業社會責任認知程度與組織認同之中介變數，員工的企業社會責任認知程度對知覺外部聲望有正向的影響，而更進一步影響組織認同。 2.企業志工參與和組織認同具有正向關係，佐證當企業的社會責任相關活動能滿足員工的心理需求時，員工將會傾向認同該企業。 3.組織認同與顧客導向、工作滿足及組織承諾皆存有正向的影響關係。 4.顧客導向、工作滿足和組織承諾皆與組織公民行為有正向的影響關係，其中顧客導向和組織承諾的影響力皆大於工作滿足。 / The increasing development of corporate social responsibility has become a prevalent concern for business sustainability practices. In comparison to the viewpoint of outside stakeholders, employees play unique roles for their company for two reasons: (1) employees are closer to corporate core business (2) employees participate more easily in CSR activities and policy formulation. Therefore, this study aims to establish a model to understand how employees’ perceived CSR and participation in employee volunteer program (EVP) relate to their organizational citizenship behavior. This study also investigates whether perceived CSR and EVP participation has positive effects on organizational identification; whether perceived external prestige mediates the relationship between perceived CSR and organizational identification; and whether organizational identification acts as the antecedent of job satisfaction, organizational commitment and customer orientation. The model concept is based on the model of CSR and employee-company identification established by Kim et al. (2010), and modified by adding some employees’ attitude constructs. The survey, conducted by convenience sampling, consists of a total of 316 participants whose companies have EVP. Utilizing confirmatory factor analysis (CFA) and structural equation modeling (SEM), the results are as follows: 1.Perceived external prestige is a partial mediator between perceived CSR and organizational identification. Meanwhile, perceived CSR positively affects perceived external prestige, and perceived external prestige has positive relationship with organizational identification. 2.The relationship between EVP participation and organizational identification is positive, which means employees tend to identify with their company when they are mentally satisfied by CSR activities. 3.Organizational identification positively affects variables, such as customer orientation, organizational commitment and job satisfaction. 4.The attitude factors that positively affect employees’ organizational citizenship behavior include customer orientation, organizational commitment and job satisfaction. Further, the impact of customer orientation and organizational commitment are greater than job satisfaction.
