心理韧性对理工科博士生创新能力的影响自我效能感的中介作用及学业投入的调节作用

为考察个体心理韧性、自我效能感和学业投入对理工科博士生创新能力的影响，本研究通过问卷调查了国内464名理工科博士生。结果显示：心理韧性对预测博士生的创新能力有正向作用；我效能感在心理韧性与创新能力之间起部分中介作用，即博士生心理韧性能够通过增强自我效能感进而提升创新能力；学业投入在自我效能感与创新能力的关系中起调节作用，无论学业投入处于低、中、高水平。自我效能感都能显著提高博士生的创新能力水平，高学业投入使得自我效能感对创新能力的影响更明显。这一结果对于高校更科学有效地选拔具有创新潜质的博士生，以及培养并提升博士生创新能力具有启示意义。

The Influence of Individual Resilience on the Innovation Ability of Doctorial Students in Science and EngineeringThe Mediating Role of Self-Efficacy and The Moderating Role of Academic Engagement

464 doctoral students in science and engineering in China were investigated by questionnaire examine the impact of individual resilience, self-efficiency and academic engagement on their innovation ability. The results show that individual resilience has a positive effect on predicting the creativity of doctoral students; self-efficacy plays a partial intermediary fole between resilience and creativity. High resilience enhances the level of self-efficacy, and it in turn increases doctoral students'' creativity. Academic engagement moderates the association between self-efficacy and creativity. Self-efficacy has a positive influence on doctoral students'' creativity when the level of academic engagement is low, medium or high. But high academic engagement can promote the effect of self-efficacy on innovation ability. Those findings reveal the influence mechanisms of resilience on creativity and increase the level of individual creativity. Universities should pay attention to improving doctoral students'' resilience, enhancing their self-efficacy, and academic engagement.
