In a research article related to green supply chain practices (GSCM) and their impact on environmental (EP) and financial performance (FP) of firms, I introduced contingent role of institutional pressures (IP), one of the reviewers raised a concern stating that the earlier part (GSCM-->EP-->FP) is (based on) practical framework and I'm proposing contingent effect of IP on the basis of theoretical framework (institutional theory). He/she asked me to explain 'why' I'm doing so. I'm wondering that how can I justify this because, besides a theoretical underpinnings, it seems that regulatory institutions also belong to 'practical (regulatory) framework. Seeking guidance.
