AbstractMany companies have become aware of the importance of green creativity for sustainable development in the face of an increasingly critical global environmental situation. As employee's green creativity serves as an important foundation for corporate green creativity, we divide green creativity at the employee level into green incremental and radical creativity and construct a theoretical framework to assess the effects of corporate environmental ethics on these two types of green creativity. We distribute 195 valid leader–employee matching questionnaires to a variety of companies in China. We find that corporate environmental ethics has a positive effect on both incremental and radical green creativity. Furthermore, we discover that employee environmental commitment partially mediates the association between corporate environmental ethics and the two types of green creativity identified above. Sustainable human resources management (HRM) plays a moderating role between corporate environmental ethics and environmental commitment and moderates the indirect effects of corporate environmental ethics on the two types of green creativity through the promotion of environmental commitment. These findings suggest that companies should improve their corporate environmental ethics and sustainable HRM to encourage employees to enhance their own environmental commitment and, in turn, increase their green incremental and radical creativity levels. Our study has significant implications for enhancing business innovation and achieving sustainable development. Finally, we also address the theoretical and practical implications of our findings.
