This study aims to investigate the mediation effect of green product and green process innovation by focusing on the role of internal and external environmental orientation over firm performance to expand researches on environmental orientation. With this aim, a conceptual model has been recommended by unifying institutional theory and natural resource-based view. Data collected from 315 firms who have ISO14001 Environmental Management Certificate and took part in Turkey’s first and second ISO 500 Industrial Enterprises list in 2018 have been tested by using SmartPLS 3 software as part of Structural Equation Modelling. Empirical proofs show that internal and external environmental orientation has a positive effect on both green product innovation and green process innovation. Additionally, it has been concluded that internal environmental orientation has a direct positive effect on firm performance, while external environmental orientation has an indirect effect, which is through green product and green process innovation. The reason could be rooted in the ecological responsibility feeling of internal environmental orientation. External environmental orientation, though, could be limited only with fulfilling legal requirements with legitimacy acquiring desire. Firms strategically directed to the green product and green process innovation by doing more than the laws require and taking the lead could increase their firm performance. These findings contribute to theory and practice, enriching our understanding of how two dimensions of environmental orientation affect firm performance.
