This study explores the impact of psychological ownership on volunteer commitment within volunteer organizations. By introducing psychological ownership as a new variable, this research aims to enhance volunteer commitment through improved management practices and innovations. The study involved a random sample of educational volunteers from primary schools, who completed questionnaires after being briefed by the researchers. An analysis of 212 valid responses revealed that psychological ownership significantly influences organizational commitment, with volunteer motivation acting as a partial mediator. Based on these findings, the study suggests two innovative strategies to promote volunteer commitment. First, developing a diverse knowledge base for volunteer managers to improve their leadership and collaboration skills. Second, integrating volunteers as a subsystem within the staff through decentralized decision making, thereby increasing their participation and sense of responsibility. These insights extend the concept of psychological ownership to volunteer settings, offering theoretical contributions and practical implications for enhancing volunteer retention rates and organizational effectiveness.
