This comprehensive Handbook presents an in-depth examination of buyer-supplier relationships, an area of crucial importance for organisations managing increasingly complex and volatile supply chains. Drawing on interdisciplinary contributions from both academics and practitioners, it explores the multi-dimensional nature of these relationships across a range of sectors. Leading experts investigate how contemporary forces such as digitalisation, sustainability and innovation are reshaping the dynamics between buyers and suppliers, leading to more strategic, resilient and value-driven partnerships. Chapters assess core concepts including collaboration, governance, performance measurement and risk management in differing global contexts. Through empirical insights, conceptual frameworks and practical recommendations, this book provides an understanding of cultural, regulatory and structural variations in buyer-supplier relationships. The Research Handbook on Buyer-Supplier Relationships is a valuable resource for scholars and students of business and management, public administration and organisational behaviour. It is also prime reading for practitioners in business, organisation management and sales navigating the strategic challenges of modern purchasing and supply management.
