Abstract
As environmental protection has gradually become the focus of enterprises' development, employee green behavior becomes an important and key antecedent to study this issue, but there have been less studies conducted with knowledge management. As a result, drawing on the theory of planned behavior and the organizational support theory, this study investigates how environmental knowledge practices (environmental knowledge sharing and environmental knowledge application) affect employee green behavior by using a questionnaire survey administered to 266 employees in China to reveal their complex relationship mechanism. The results show that environmental knowledge application and environmental knowledge sharing have a positive effect on employee green behavior; environmental behavioral intention mediates the relationship between environmental knowledge application and employee green behavior, and between environmental knowledge sharing and employee green behavior; green perceived organizational support positively moderates the relationship between environmental behavioral intention and employee green behavior. The findings shed new light on the development of employee green behavior literature and provide practical reference for strategies related to environmental protection for managers.
