Implementing sustainable sourcing practices (SSP) relies strongly on organizational decisions and the motives behind these decisions. However, little is known about how SSP are influenced by organizational motives (OM). To address this gap, we developed a multifaceted framework based on stakeholder theory (ST) that enables enhanced knowledge of OM, such as instrumental motives (IM), relational motives (RM), moral motives (MM), and their influence on SSP by incorporating the moderating role of stakeholder pressure (STP). Data were compiled from 308 Pakistani manufacturing organizational respondents and assayed by partial least squares structural equation modeling (PLS-SEM). The deliverables of SEM validated that all OM directly impact SSP. Further, STP expressively moderated the targeted relations in confounding ways and organizational size moderately distinguished small and larger organizations. Importance-performance map analysis also revealed that RM have a greater importance value (0.201) and MM have a greater performance value (71.833) than all exogenous variables. This research offers several key contributions. First, all three OM (IM, RM, and MM) significantly improve SSP directly, and with the moderation of STP and organizational size, which signifies the salience of ST and provide diverse conclusions. Second, OM operationalize SSP and suggest ways to execute them to meet the organizational environmental goals. Third, this study examines how SSP implementation requires the source function to reconsider its key motives for sustainability endeavors.

实施可持续采购实践 (SSP) 在很大程度上依赖于组织决策以及这些决策背后的动机。然而，人们对于 SSP 如何受到组织动机 (OM) 的影响却知之甚少。为了解决这一差距，我们开发了一个基于利益相关者理论（ST）的多方面框架，该框架可以增强对 OM 的了解，例如工具动机（IM）、关系动机（RM）、道德动机（MM）及其对 SSP 的影响纳入利益相关者压力（STP）的调节作用。数据来自 308 名巴基斯坦制造组织受访者，并通过偏最小二乘结构方程模型 (PLS-SEM) 进行分析。SEM 的交付成果证实所有 OM 都会直接影响 SSP。更远，STP 以令人困惑的方式明显地调节了目标关系，而组织规模则适度区分了小型组织和大型组织。重要性-绩效图分析还显示，与所有外生变量相比，RM 具有更大的重要性值（0.201），MM 具有更大的绩效值（71.833）。这项研究提供了几个关键贡献。首先，所有三个 OM（IM、RM 和 MM）都直接显着提高了 SSP，并且随着 STP 和组织规模的调节，这表明 ST 的显着性并提供了不同的结论。其次，OM 实施 SSP 并提出执行方法，以实现组织的环境目标。第三，本研究探讨了 SSP 的实施如何要求源功能重新考虑其可持续发展努力的关键动机。
