In this study, descriptive statistical approaches, Cronbach’s alpha, EFA exploratory factor analysis, and multivariate regression were used. According to the study's findings, five variables positively influence employees’ knowledge-sharing behavior: trust, communication, leadership attention, rewards, and information technology. The study's findings have made an academic contribution by providing empirical data and enriching theory on knowledge-sharing behavior in the banking sector. Furthermore, the research has offered a number of management implications to encourage knowledge-sharing behavior among employees in the VietinBank system in particular and may offer, in general, tentative insights for state-owned commercial banks operating in similar institutional environments https://ijism.isc.ac/article_739043_50e6cf8bf96b3387329985bf430536da.pdf
