Several previous studies have adopted conceptual [45, 46] or qualitative approaches [14, 47, 48] to understand the motivators underlying knowledge sharing behavior. Moreover, existing studies have reported aspects of motivational factors
(e.g. extrinsic and intrinsic motivators) as antecedents of knowledge sharing behaviors [18, 24], while Tyler and Blader [25] have suggested that intrinsic
motivators could be important determinants of knowledge worker behaviors. This study contributes to the advancement of theory in two key ways: first, this study simultaneously investigates both extrinsic and intrinsic motivators affecting employee knowledge sharing behaviors. Second, this study proposes a theoretical model that combines a motivational perspective with TRA to illustrate the relationships between different kinds of motivation (extrinsic and intrinsic) and employee knowledge sharing attitudes and intentions.
