Green creativity is a vital element in driving green innovation and achieving sustainable development for corporates, but it is not clear whether corporate’s environmental responsibility practice contributes to employees’ creativity. This study is aimed at determining whether employees’ perception of corporate environmental responsibility fosters their green creativity and exploring the underlying mechanism and boundary condition. We conducted a survey of 413 employees working in the manufacturing sector in China at two different time points. The study confirms that perceived corporate environmental responsibility has a positive relationship with both organisational identification and green creativity. Moreover, organisational identification mediates the relationship between perceived corporate environmental responsibility and green creativity. Perceived person-organisation fit moderates the relationship between PCER and organisational identification, as well as the relationship between organisational identification and green creativity, and also the indirect link between perceived corporate environmental responsibility and green creativity via organisational identification. This study theoretically expands a new way to promote green creativity and fills the gap in the existing research on corporate environmental responsibility and green creativity. We also provide a new perspective of psychological connection to explain the underlying mechanism and boundary condition of perceived corporate environmental responsibility and green creativity. In practice, our research can make managers pay attention to the fulfilment of corporate environmental responsibility and the cultivation of organisational identification and high person-organisation fit, so as to enhance the green creativity of employees and realise the sustainable development of the organisation.
