Examining Public Service Motivation's Impact on Organizational Commitment: Focusing on Moderating Roles of Hygiene and Motivation Factors

Despite previous studies on public service motivation among public sector employees, the empirical analysis of the influential contextual conditions that moderate public service motivation's impact on employees' work attitudes remains inadequate. Given these limitations, this study examines public service motivation's effects on public employees' organizational commitment and investigates how Herzberg's hygiene and motivation factors moderate the relationship between these aspects in the context of South Korea's central government. For this, we used the data of 1021 public employees from the Differences in the Values of Different Generations of Public Officials and Organizational Innovation Survey, which the Korea Institute of Public Administration had conducted in 2022. We analyzed the data through hierarchical multiple regression analyses, and the results indicated that public service motivation exerts a positive effect on organizational commitment. Specifically, hygiene factors weaken the positive relationship between public service motivation and organizational commitment, while motivation factors have a moderating effect that strengthens said relationship. These findings suggest that, in order to enhance organizational commitment among motivated public employees, human resource management practices should prioritize motivational factors that can enhance job content, meaning, and autonomy instead of solely focusing on providing monetary incentives or improving external conditions.
