This study aims to examine the influences of environmental and personal factors on knowledge-sharing behaviour (KSB) of academics and whether more influence leads to superior innovative work behaviour (IWB) at the tertiary level in Vietnam. A questionnaire survey was conducted as part of the study, including 320 academic staff at Hanoi University, one of the leading public universities in Vietnam. This study applies the structural equation modelling (SEM) to investigate the research model based on social cognitive theory (SCT). The results show that two environmental factors (subjective norms and trust) and two personal factors (knowledge self-efficacy and enjoyment in helping others) significantly influence KSB. The results also indicate that employee willingness to share knowledge enables the organisation to promote innovative work behaviour. The study context was limited to only one Vietnamese university. It appears that the part of a bigger picture of knowledge sharing (KS) in Vietnamese universities is likely to be lost. However, given the previous studies on knowledge sharing in both developed and developing countries, it could be expected that the results of this study can be taken forward by university leaderships, academic staff and researchers in other contexts as well. A clear understanding of the critical factors that influence KSB towards promoting innovative work behaviour may help university leaders to develop suitable and evolving strategies to address the challenges of knowledge sharing. This study contributes to the growing literature on the relationships among environmental and personal factors and KSB towards promoting innovative work behaviour.

Abstract-Although knowledge sharing (KS), the key to creativity and innovation, are increasingly common in organisations, research on the relationship between knowledge sharing behaviour (KSB) and transactive memory system (TMS) and its effect on innovative work behaviour (IWB) is relatively rare. Prior studies have reported that KS influences IWB in organisations. However, the effect of KSB on IWB and the join influence between TMS on KS and IWB have not been adequately investigated in past research. Therefore, the goal of this researchin-progress is to propose a conceptual model comprising three construct domains including KSB, TMS quality and IWB to examine the impact of the KS practices of employees on their IWB in organisations. We advance to conduct a survey to examine our discussion of the proposed conceptual model. It is expected that this research will contribute to the deeper understanding of the effects of KSB and TMS on IBW within organisation. Implications and future research are also proposed.
