中文摘要：

基于压力交互理论与工作要求一资源模型，以932名制造业一线员工为研究对象，首先检验了制造业一线员工的工作要求对离职倾向的影响，进而考察了冲动性人格与社会支持对工作要求与离职倾向关系的链式调节作用。研究结果发现，制造业一线员工的工作要求对离职倾向具有正向影响；冲动性人格调节工作要求对离职倾向的影响；社会支持在冲动性人格对工作要求与离职倾向关系的调节效应中起部分中介作用，即冲动性人格通过影响社会支持进而调节工作要求与离职倾向间的关系。研究结论对于深入理解制造业员工的高离职率提供了一个新的理论视角。

英文摘要：

Based on transactional theory and job-demands resources model, we argue that job de- mands influence turnover intention. In addition, we further propose that impulsivity facilitate the rela- tionship between job demands and turnover intention. Finally, it is hypothesized that the moderating effects of impulsivity are mediated by manufacturing worker＇s social support. Data from 932 employ- ees were collected across 3 time periods. Results of hierarchical regression analysis revealed that. （1） manufacturing worker＇s job demands had a significantly positive influence on turnover intention; （2） impulsivity facilitated the positive relationship between job demands and turnover intention, such that the positive relationship was stronger when manufacturing worker＇s impulsivity was high; （3） the moderating effects of impulsivity were mediated by social support, social support that influenced by impulsivity buffered the positive relationship between manufacturing worker＇s job demands and their turnover intention. The theoretical and managerial implications of our findings, limitations, as well as future research directions were discussed finally.
