Under Dual Perspective of Work Exchange and Social Exchange between Leaders and Members in Organization

This paper explored LMX´ impact on employees´ organizational affective commitment and chose the perceived organizational support as a mediated variable, using structural equation model technology to verify the relationship of them. The results showed that: affection, loyalty and professional respect had a significant impact on affective commitment but the result of contribution is not significant. So work exchange (contribution) was different from social exchange (affect, loyalty and professional respect) in the influence on employee´s organizational affective commitment. Perceived organizational support had a mediated effect between the affect exchange and affective commitment in the organization. Leader-member relationship had an important implication on the employee-organization relationships. The exchanges of different dimensions between leaders and members were different no matter for the affected contents of the attitude to the organization of the employee or for the affecting mechanism.
