Today, where competition is experienced globally, leaders play an important role in the success of national and international companies. Leaders have to manage human resources and establish a good organization in order to cope with the increasingly complex international competition. Social capital, intellectual capital, emotional labour and innovative climate, which are among the intangible values of enterprises, have become important variables in the success of the leader. The purpose of the study is to investigate the mediating role of social capital and intellectual capital in the impact of leadership behaviour on emotional labour and innovative climate. The data was collected through conducting a survey with 91 managers and 457 employees to represent five-star hotel businesses. The theories of social capital, intellectual capital, emotional labour and innovative climate constitute the methodological framework of the study. Research hypotheses were questioned using Path Analysis of Wright with Baron and Kenny's mediating variable conditions using SPSS-AMOS. Research results show that social capital had a fully mediating role in the effect of leadership behaviour on emotional labour and innovative climate. Intellectual capital had a fully mediating role in the effect of leadership behaviour on emotional labour, and a partial mediating role in the effect on innovation climate. It was observed that leadership behaviour, social capital, and intellectual capital did not have a significant positive effect on emotional labour. Managers who want to increase the level of emotional labour, innovative climate, social and intellectual capital in their hotels should develop leadership behaviours effectively. The research provides a comprehensive explanation of the relationships of research variables to enable more effective applications in hotel organizations.
