基于情感事件理论和人一境互动视角，应用bootstrap法根据260份有效问卷的数据执行路径分析，探讨时间领导对员工助人行为的影响机制。结果发现：时间领导正向预测助人行为；时间领导影响助人行为部分是通过和谐式激情与强迫式激情的并行多重中介作用来实现的，且和谐式激情的个别中介效应较大；由于主动型人格的调节作用，时间领导影响助人行为的直接效应和总效应在员工主动型人格较低时更强。

英文摘要：

As the cooperation in multiple tasks between employees is increasingly necessary for companies in today＇s dynamic business environment, facilitating helping behaviors among employees becomes a critical issue for managers. However, employees might have no time to help their colleagues due to striving to meet the deadlines themselves. To address this problem, we introduced temporal leadership--which could effectively allocate and utilize the time resources of employees--to facilitate employees＇ helping behavior. Then we developed a theoretical model based on the effective event theory and the person-situation interaction perspective to explain the impact mechanism of temporal leadership on helping behavior. After that, we examined our hypotheses by using a sample of 260 employees from three provinces in southern China. By implementing path analysis via a procedure of bootstrapping with Mplns 6.10, our analyses indicated that： （I） Temporal leadership positively predicted employees＇helping behavior; （2） Both harmonious passion and obsessive passion simultaneously played the role of mediator in the relationship between temporal leadership and helping behavior in our multiple mediation model, and the specific mediating effect of harmonious passion was relatively stronger; （3） Proactive personality moderated the relationship between temporal leadership and helping behavior, so that the direct and total effect of temporal leadership on helping behavior were both stronger for the employees with lower level of proactive personality. This study contributed to extant literature in three ways. Firstly, by introducing temporal leadership, it could not only justify the theoretical value of this construct, but also broaden our understanding on the factors conducive to helping behavior. Secondly, this study could give more details about why as well as how temporal leadership was able to facilitate helping behavior by integrating the multiple mediations of the two types of passion and the moderation of proact
