工作压力双路径视角下国防研发人员主动性行为形成机理：职场精神力的调节效应

研发人员主动性行为是实现国防科技企业创新与高质量发展的重要竞争力来源，但有关工作压力背景下主动性行为的形成机理仍缺乏实证探索。以双元工作压力理论为基础，探讨了挑战性压力与阻碍性压力对国防研发人员主动性行为的作用机制，重点考察了工作繁荣与情绪耗竭的中介作用以及职场精神力的调节效应。针对8家国防科技企业及科研院所的630名研发人员开展实证研究，分析结果表明：挑战性压力和阻碍性压力分别对主动性行为起正向与负向作用；工作繁荣和情绪耗竭分别在挑战性压力、阻碍性压力与主动性行为间起部分中介作用；职场精神力正向调节挑战性压力与工作繁荣的关系，负向调节阻碍性压力与情绪耗竭的关系；职场精神力不仅调节了挑战性压力通过工作繁荣影响主动性行为的间接效应，还调节了阻碍性压力通过情绪耗竭影响主动性行为的间接效应。

Proactive Behavior of R&D Personnel in Military Industry under the Dual Path of Work Stress: The Moderating Effect of Workplace Spirituality

The proactive behavior of R&D personnel is an important source of competitiveness for innovation and high-quality development of military industry enterprises. However, the formation mechanism of proactive behavior under the background of work stress still lacks empirical exploration. Based on the theory of dual work stress, this paper explores the influence mechanism of challenge stress and hindrance stress on the proactive behavior of R&D personnel, specially focusing on the mediating role of thriving at work and emotional exhaustion and the moderating role of workplace spirituality. We collected questionnaire data of 630 R&D employees from 8 enterprises and research institutes in military industry. The results show that: challenge stress and hindrance stress have positive and negative effects on proactive behavior respectively;thriving at work partially mediates the effect of challenge stress on proactive behavior, and emotional exhaustion partially mediates the effect of hindrance stress on proactive behavior;workplace spirituality positively moderates the relationship between challenge stress and thriving at work, while negatively moderates the relationship between hindrance stress and emotional exhaustion; workplace spirituality further moderates the indirect effects of challenge stress on proactive behavior through thriving at work, and also the indirect effects of hindrance stress on proactive behavior through emotional exhaustion. Theoretical and practical implications of the findings are also discussed.
