摘要：基于角色积累理论，本研究旨在探究副业心理授权对主业工作绩效的影响，并分别构建情感路径和认知路径，以解释副业心理授权的跨领域溢出效应。通过对452份三阶段有效样本进行实证分析，本研究发现：副业心理授权可以通过增加主业工作中的积极情感，提高主业创新绩效，但不能促进主业任务绩效；副业心理授权将通过增加主业工作中的注意力残留，降低主业创新绩效和主业任务绩效；当主业工作中的积极情感和注意力残留共同发挥双中介作用时，副业心理授权对主业创新绩效和主业任务绩效的总体效应值分别为正和负，证明了双刃剑效应的存在。深入探讨副业心理授权对主业工作绩效的影响，有助于深化对副业与主业之间关系的理解，扭转社会对从事副业的偏见，帮助人们树立起对于副业活动的正确认识，从而为今后的管理理论和实践发展提供启示与借鉴。

Abstract: Based on the role accumulation theory, this study aims to explore the impact of side job psychological empowerment on the job performance of the main job, and construct emotional paths and cognitive paths respectively to explain the cross-domain spillover effects of side job psychological empowerment. Through the empirical analysis of 452 three-stage effective samples, this study found that: psychological empowerment of side job can improve the innovation performance of the main job by increasing the positive emotion in the main job, but can not promote the task performance of the main job; The psychological empowerment of the sideline will reduce the innovation performance and task performance of the main occupation by increasing the attention residue in the main occupation; When the positive emotion and attention residual in the main job play a double mediating role together, the overall effect values of the psychological empowerment of the side job on the innovation performance of the main job and the task performance of the main job are positive and negative respectively, which proves the existence of the double-edged sword effect. The in-depth study of the impact of psychological authorization on the performance of the main job will help deepen our understanding of the relationship between the side job and the main job, reverse the social prejudice against the side job, and help people establish a correct understanding of the side job activities, so as to provide inspiration and reference for the future development of management theory and practice.
