Today's competition is among supply chains rather than enterprises as independent actors. Additionally, the success of the actors within the SC network, through the improvement of the global performance, depends on how well they handle the growing environmental problems. For this reason, much attention is given to the greening concept. This paper aims to investigate the Green Human Resource Management (GHRM) impact on Green Supply chain Management (GSCM) in a strategic sector, namely the pharmaceutical sector. Our interest to deal with this issue was aroused by the fact that there are no studies exploring the causality relationships in the pharmaceutical sector in Saudi Arabia. Based on deductive methodology, a questionnaire has been developed. A research sample included 109 pharmaceutical companies operating in KSA. The results highlight a significant impact of GHRM on GSCM practices. In other words, training and performance appraisal, recruitment, and eco-behavior-based rewards influence GSCM practices positively. Based on the results, the study provides new theoretical insights and practical suggestions.

Lots of work has been conducted to explore and explain inter-organizational relations between supply chain partners. However, we have noticed that there is no accurate agreement between authors. Therefore, to better understand this disparity, the authors have studied supply chain inter-organizational relationship dynamics in different industries to bring out an analytical framework that allows a better understanding of such an issue. Further, the framework is subjected to expert’s opinion and ranked using the Technique for Order of Preference by Similarity to Ideal Solution (TOPSIS) approach. These case studies instruct professionals and researchers so that they bring up their level of abstraction that remains appropriate to catch this dynamic in order to guide decision-making and future research and studies.
