The purpose of this paper is to reveal the relationships among green organizational culture, green innovation and competitive advantage. These relationships were assessed using structural equation modeling. Data were gathered from full-time hotel employees (N: 293) and managers (N: 192) in the Antalya region of Turkey. The results indicate that green organizational culture has a positive effect on green innovation and competitive advantage. Accordingly, green organizational culture is an important determinant for green innovation and competitive advantage. In addition, green innovation acted as a full mediator of the effects of green organizational culture on competitive advantage. Specifically, green organizational culture predicted green innovation, which in turn predicted competitive advantage. Finally, considering that causal studies on green innovation in the hotel industry are limited, this study may contribute to understanding how green innovation affects competitive advantage in the hotel industry.
