<b>A Study of the Effects of Job Insecurity on Organizational Citizenship Behavior Based on the Chained Mediating Effects of Emotional Exhaustion and Organizational Identification</b>

This study focuses on the mechanisms of job insecurity on organizational citizenship behavior, aiming to reveal the dynamics of employee behavior in an uncertain employment environment. A time-lagged follow-up design was used to test the multiple paths of action of job insecurity from 330 valid questionnaires. It was found that the total effect of job insecurity on organizational citizenship behavior was -0.579, with a direct effect of -0.209 and a total indirect effect of -0.370. Specific mediating paths included (1) job insecurity indirectly affecting organizational citizenship behavior through emotional exhaustion, with an indirect effect value of -0.264; (2) indirectly affecting through organizational identification, with an indirect effect value of - 0.062; (3) job insecurity→emotional exhaustion→organizational identity→organizational citizenship behavior with a chain mediated effect value of -0.045. The results showed that the mediated effect of emotional exhaustion was the most significant, explaining 45.60% of the total effect, revealing the intrinsic mechanism by which job insecurity weakened organizational citizenship behavior through the cognitive-emotional path.本研究聚焦于工作不安全感（Job Insecurity）对组织公民行为（Organizational Citizenship Behavior）的作用机制，旨在揭示不确定就业环境中员工行为的动态演化规律。本研究采用时滞追踪研究设计，依托330份有效问卷对工作不安全感的多重作用路径进行检验。研究结果显示，工作不安全感对组织公民行为的总效应为-0.579，其中直接效应为-0.209，总间接效应为-0.370。具体中介路径包括：（1）工作不安全感通过情绪衰竭（Emotional Exhaustion）间接影响组织公民行为，间接效应值为-0.264；（2）通过组织认同（Organizational Identification）间接产生影响，间接效应值为-0.062；（3）工作不安全感→情绪衰竭→组织认同→组织公民行为的链式中介效应值为-0.045。结果表明，情绪衰竭的中介效应最为显著，可解释总效应的45.60%，揭示了工作不安全感通过认知-情感路径削弱组织公民行为的内在作用机制。
