The Relationship between Perceived Organizational Support and Organizational Citizenship Behavior: The Role of Affective Commitment

In light of the rapid changes made in the global economic environment in recent years, organizational citizenship behaviour (OCB) has become a significant focus of organizational behaviour research. This study aimed to explore the impact of perceived organizational support (POS) on OCB among private enterprise employees in Guangzhou, China, and to assess the mediating role of affective commitment (AC). Using quantitative approach, data were collected through a self-administered questionnaire, developed based on established measures and relevant literature, from a sample of 398 employees. Data were analyzed using SPSS version 27, incorporating descriptive statistics, reliability analysis, correlation analysis, and regression-based mediation testing. The results indicate that POS has a significant positive influence on OCB, and AC also positively impacts OCB. Furthermore, AC partially mediates the relationship between POS and OCB. These findings underscore the critical role of POS and AC in fostering OCB and provide empirical insights into the mechanisms underlying this relationship in the context of high-tech private enterprises in Guangzhou, China. The study offers a robust contribution to the literature on organizational behavior, particularly in the rapidly evolving private enterprise sector.
