摘要:Due to the intensified market competition, companies must seek lower-cost and efficient corporate management methods in order to sustainably develop. The concept of high performance work system (HPWS) came into being in this situation. The main purpose of this research is to explore the relationship between high-performance work systems and employee well-being and organizational citizenship behavior. This research takes China’s small and medium-sized enterprises(SMEs) as the research objects of the survey. After analysis using SmartPLS, it is found that the high-performance work system will have a positive and significant impact on well-being and employee citizenship behavior. At the same time, wellbeing plays a mediator variable in the relationship between the high-performance work system and employee citizenship behavior.
