Although the importance of integrating different Green Supply Chain Management (GSCM) activities has been highlighted in the literature, the potential interdependencies between these practices and their performance impacts have not been investigated. The purpose of this study is to examine the collective impact of internal and external GSCM practices on two aspects of environmental performance: environmental impact and environmental cost savings. GSCM is proposed as a collective competency, combining four distinct, but interrelated, sets of practices: environmental management systems, eco design, source reduction and external environmental practices. Using survey data from 138 Omani manufacturing firms and Structural Equation Modelling, we find strong empirical support for the complementarity of GSCM practices. We find a strong positive relationship between the level of collective GSCM competency and the environmental impact achieved. Our findings support the belief that complementarities between GSCM practices lead to better performance. Managers should therefore focus on implementing bundles of GSCM practices rather than searching for individual best practices. We find an indirect, mediated influence on environmental cost savings, which is consistent with previous results in other emerging market contexts.
虽然文献强调了整合不同绿色供应链管理（GSCM）活动的重要性，但这些实践之间的潜在相互依存关系及其对绩效的影响尚未得到研究。本研究旨在考察内部和外部 GSCM 实践对环境绩效的两个方面的综合影响：环境影响和环境成本节约。GSCM 被提议为一种集体能力，结合了四个不同但相互关联的实践集：环境管理系统、生态设计、源头减排和外部环境实践。我们使用来自 138 家阿曼制造企业的调查数据和结构方程模型，为 GSCM 实践的互补性提供了强有力的实证支持。我们发现，集体 GSCM 能力的水平与实现的环境影响之间存在很强的正相关关系。我们的研究结果支持了这样一种信念，即 GSCM 实践之间的互补性会带来更好的绩效。因此，管理者应该专注于实施 GSCM 实践的集合，而不是寻找个别最佳实践。我们发现对环境成本节约的间接、中介影响，这与其他新兴市场背景下的先前结果一致。
