In this study, we first investigate the association between idea implementation and sustainable innovative work behaviour (SIWB), followed by an exploration of the moderating effect of cooperative behaviour and knowledge-sharing culture on such a relationship. The study is based on multi-source data collected from 189 employees and their supervisors across diverse units in the home appliances industry. Regression analysis confirmed a direct positive relationship between idea implementation and SIWB. While knowledge-sharing culture alone did not moderate the relationship between idea implementation and SIWB, a significant three-way interaction emerged among idea implementation, knowledge-sharing culture, and cooperative behaviour. The highest SIWB levels occurred when there was a strong presence of both knowledge-sharing and cooperation. We contribute valuable insights to the literature on sustainability and innovation by demonstrating how knowledge circulation and individual cooperation facilitate the transformation of ideas into sustainable innovative behaviour. https://ijms.ut.ac.ir/article_103242_ed6898648ece1631de6b1b96381d48b5.pdf
