Empirical Study on Supplier Relationship Stability and Corporate Cost Structure

Abstract

This study uses A-share listed companies in my country from 2018 to 2022 as research samples and employs multiple regression analysis to empirically explore the impact and mechanism of supplier relationship stability on corporate cost structure. This study aims to reveal the intrinsic relationship between the two and provide theoretical support and practical guidance for enterprises to optimize cost management. The results show that supplier relationship stability significantly and negatively affects corporate procurement and transaction costs, thereby optimizing the cost structure of the company. Supply chain collaboration efficiency partially mediates the relationship between the two. Enterprise size and ownership structure significantly moderate this impact. This study enriches interdisciplinary research on supplier relationship management and cost structures, expands the application scenarios of relevant theories, and provides empirical evidence for enterprises to improve cost competitiveness through stable supplier relationships.
