基于计划行为理论的视角，以可培训的政治技能为突破口，通过来自12家企业234份员工的研究样本，探究员工政治技能对促进员工进行跨界行为的影响机制。结果发现：员工政治技能对跨界行为有显著正向影响；跨界效能感在政治技能与跨界行为之间起部分中介作用；员工权力距离负向调节了员工政治技能与跨界效能感之间的关系；并负向调节了跨界效能感在政治技能与跨界行为之间的间接效应。研究结果丰富并拓展了政治技能和跨界行为的相关研究，对如何激励组织中出现更多跨界行为有较重要的指导意义。

Based on the perspective of planning behavior theory, starting from the trainable political skills, this study explores the impact mechanism of employees' political skills on promoting their active boundary spanning behavior through 234 research samples from 12 enterprises. The results show that employees' political skills have a significant positive impact on boundary spanning behavior; the boundary spanning efficacy plays a partial intermediary role between political skills and boundary spanning behavior; employee power distance negatively regulates the relationship between their political skills and boundary spanning efficacy, and negatively regulates the intermediary role of boundary spanning efficacy between political skills and boundary spanning behavior. The research results can enrich and expand the relevant research on political skills and boundary spanning behavior, and can provide insights on how to encourage more boundary spanning behavior in organizations.
