Fostering Green Innovations in SMEs: The Serial Interplay of Green HRM Practices, Green Strategy and Green Knowledge Sharing

ABSTRACT This study examines the impact of green human resources management (HRM) practices on employee green innovation, focusing on the mediating and moderating roles of green strategy and green knowledge‐sharing behaviour. Data were collected from 387 owner‐managers and employees of small‐ and medium‐sized enterprises (SMEs) in Ghana. The results show that green HRM practices positively influence employee green innovation. Although green strategy did not moderate the relationship between green HRM practices and green innovation, it significantly mediated the effects of green HRM practices on both green innovation and green knowledge sharing. Sequentially, green HRM practices strengthen green strategy, which promotes green knowledge sharing and ultimately enhances employee green innovation. These findings highlight how SMEs in developing economies can leverage human resource practices and strategic relational mechanisms to drive green innovation.
