Explaining the framework of relationships between knowledge sharing and organizational citizenship behavior in the base of positive organizational behavior

Knowledge sharing can be considered as an organizational behavior with a great importance which is affected by the other organizational behavior variables. This paper with a descriptive-survey approach، tries to investigate knowledge sharing behavior as a substantial aspect of knowledge management and to analyze its relationships with psychological empowerment and psychological capital as the main concepts of positive organizational behavior. Furthermore، the mediating role of organizational citizenship behavior has been regarded in the abovementioned relations and finally a framework has been presented which explains the relationships among these variable and concepts. Research questionnaire was distributed among a random sample of the Iranian Airports Holding Company. Collected data have been analyzed through different descriptive and inferential statistical techniques such as regression analysis and path analysis. Findings supported the presented conceptual framework and also verified the mediating role of organizational citizenship behavior in the relationships of psychological capital، psychological empowerment and knowledge sharing behavior. Furthermore، results revealed that the mediating role of the organizational citizenship behavior according to psychological empowerment is slightly greater than psychological capital.
