活动简介：
This study investigates how ESG disclosure disparities between suppliers and buyers influence supplier rankings and relationship stability within buyer organizations. Drawing on social network theory, dynamic relationship management frameworks, and principal-agent theory, we explore the dual-edged effects of ESG gaps on top supplier selection, retention, and governance dynamics. Using a longitudinal dataset spanning 1,416 supplier-buyer relationships across 30 industries and 11 Global Industry Classification Standard (GIC) sectors from 2017 to 2021, we find that suppliers with higher ESG disclosure relative to their buyers face challenges of initial selection due to perceived value misalignment and increased transaction costs. These same disparities, however, ultimately enhance long-term retention by reducing monitoring costs, fostering trust, and creating sustainability network capital. Furthermore, supplier and buyer eigenvector centrality play pivotal moderating roles: supplier centrality amplifies the positive impact of ESG disparities on rankings by leveraging structural power and information control, while buyer centrality diminishes these benefits by imposing governance constraints. Our findings reconcile the tension between value alignment (ESG-driven selection) and operational efficiency (cost reduction) in sustainable supply chains, introducing the "transparency paradox"—how excessive ESG disclosure can simultaneously hinder initial partnerships and strengthen long-term stability. Practically, the study highlights strategic implications for suppliers to balance disclosure strategies with network positioning while buyers must navigate power dynamics to avoid undermining collaborative ESG goals. This research advances the theoretical understanding of sustainable supply chain management and provides actionable insights for aligning ESG practices with competitive advantage.
