Abstract
In highly dynamic markets with regulatory, market, and technological pressures, especially in emerging economies, manufacturing companies are increasingly striving to become environmentally sustainable, mitigate environmental liabilities, and enhance their competitive advantage. This study investigates the relationship between green supply chain practices and competitive advantage in Jordanian manufacturing companies through the lens of supply chain integration as a mediator and environmental uncertainty as a moderator. From March to June 2025, a quantitative, cross-sectional survey was conducted among managers whose direct responsibilities include supply chain management, procurement, operations, environmental management, and strategic decision-making. After data screening, 254 responses eligible for analysis were analyzed using Partial Least Squares Structural Equation Modeling (PLS-SEM) in SmartPLS 4. Green supply chain practice was found to have a positive relationship with supply chain integration (β = 0.676, p < 0.001) and competitive advantage (β = 0.298, p = 0.012) among respondents. Supply chain integration was also positively associated with competitive advantage (β = 0.527, p < 0.001), and the estimated indirect effect of SC integration was statistically significant (β = 0.356, p < 0.001). The interaction between green supply chain practices and environmental uncertainty was positive and statistically significant in predicting competitive advantage (β = 0.172, p = 0.021), indicating that it might be stronger in a more uncertain environment. Overall, the results suggest that supply chain integration could be a strategy to achieve competitive results from the environment. But the findings should be viewed as statistical relationships, not causal relationships, given a cross-sectional, self-reported, single-informant, non-random sample in one national manufacturing context.
