摘要：Knowledge sharing has become a tinted area of research from past few decades. Researcher and practitioners are very keen in knowing the factors affecting the knowledge sharing, it is essential to analyze the factors that induce employees to exchange knowledge. The problem of sharing an intangible asset, in this case, the knowledge of individuals can be viewed from many perspectives: psychological, economic, organisational, sociological and technological.The aim of this article is to explore selected social psychology theories and to analyze the incentives for people to share knowledge. The article attempts to interpret the willingness to share knowledge through the Social Ex- change Theory, the Social Impact Theory, the Theory of Reasoned Action and the Theory of Planned Behaviour. This analysis leads to the following conclusions: We share our knowledge and expect a return; we share our knowledge when we believe that the benefits of this action outweigh the costs; we are pushed to share knowledge by the power of empathy. Workers’ willingness to share knowledge is influenced by three social processes: subordination, identification and internalisation; the decision to share knowledge is preceded by an intention formed under the influence of an individual attitude towards that behaviour, subjective norms and perceived behavioural control; and the decision to share knowledge is also influenced by additional components, including the knowledge and skills to implement this behaviour, environmental limitations, behavioural emphasis and habits
