本研究主要探討安全氣候知覺與風險知覺、職業安全衛生績效間之關係，並利用組織承諾做為調節變項，另驗證風險知覺在安全氣候知覺與職業安全衛生績效間的中介效果。本研究採用問卷調查收集資料，透過親送、E-Mail 或郵寄等方式，以一份公司職安衛人員卷，搭配五份該公司作業人員卷的方式，進行問卷之發送與回收，共計發出職安衛人員 65 份（收集企業組織的職業安全衛生績效）、基層作業人員325 份（收集員工對企業組織在安全氣候知覺、風險知覺及組織承諾等方面的體認），回收的有效問卷分別為職安衛人員 65 份、基層作業人員320 份，共計 65 家公司；並透過描述性統計分析、驗證性因素分析、相關分析、迴歸分析等統計方法探討變數間的關係。本研究以迴歸模式進行主要的假設驗證，經實證分析結果顯示如下： 一、安全氣候知覺對風險知覺具顯著正向影響。 二、風險知覺對職業安全衛生績效不具顯著影響。 三、安全氣候知覺對職業安全衛生績效具顯著正向影響。 四、風險知覺在安全氣候知覺與職業安全衛生績效間不具中介效果。 五、組織承諾(持續承諾)在風險知覺與職業安全衛生績效之間具調節效果。最後，依據研究結果，提出本研究結論與建議，以供後續研究參考。 This study is to explore the relationships among safety climate perception, risk perception, occupational safety and health performance, and organizational commitment. Meanwhile, the mediating effect of risk perception between safety climate and occupational safety and health performance was conducted. In addition, the moderating effect of organizational commitment between risk perception and occupational safety and healthy performance was explored.Therefore, dyad questionnaire included one staff of occupational safety and healthy performance of enterprises and five operational employees. Totally, 65 staffs of occupational safety and healthy performance of enterprises and 320 operational employees valid questionnaires were collected.The statistical methods such as descriptive statistics, confirmatory factor analysis (CFA), and analysis of correlation were used in the study. The results of the study are shown below: 1. Safety climate perception has a significantly positive influence on risk perception. 2. Risk perception has a significantly negative influence on occupational safety and health performance. 3. Safety climate perception has a significant positive impact on occupational safety and health performance. 4. Risk perception has a partially mediating effect between safety climate perception and occupational safety and health performance. 5. Organizational commitment does not have significantly moderating effect between risk perception and occupational safety and healthy performance.Based on the research results, the concrete conclusions and suggestions will provide for HRM practice and future study as references.
