The Effect of the Economic and Social Motivations on Knowledge Sharing Behavior in Megaprojects: A Mediating Effect of Environmental Dynamism

Knowledge sharing behavior is considered to accelerate information exchange among stakeholders and promote project performance in megaprojects. The motivations of megaproject stakeholders to implement knowledge sharing behavior could be divided into two classifications: economic motivation and social motivation. Environmental dynamism is often considered as unpredictable events in the environment, such as significant technological changes, boycotts by environmentalists, and so on, which could influence the effect of economic motivation and social motivation on knowledge sharing behavior in the megaproject. This paper investigates whether environmental dynamism mediates the effects and to what extent this relationship is strengthened or weakened. A total of 188 professionals participating in various megaprojects were interviewed through the questionnaire survey, and the Smart Partial least squares regression (PLS) technique was employed to analyze the data. Hierarchical regression results suggest that environmental dynamism has a strong moderating effect on the relationship between social motivation and knowledge sharing behavior. The findings contribute to understanding the effect of environmental dynamism on knowledge sharing behavior.
