Impact of Shared Auditor Spatial Layout on Supply Chain Relationships
In a globalized economy,it is no longer traditional for companies to compete against each other,but rather to compete between supply chains.The establishment of enduring and robust communication and collaboration between customers and suppliers represents a fundamental pillar in the enhancement of the overall competitiveness of the supply chain.The establishment and maintenance of stable customer relationships are vital for the continued growth in business.This is because they provide a source of revenue for suppliers and reduce operational uncertainty.Therefore,this paper combines supply chains and shared auditors to focus on the impact of the spatial layout of upstream and downstream supply chain firms and shared auditors as a whole on the supply chain relationship in terms of the geographical characteristics of the location.The study reveals the key role of shared auditors'locational characteristics in enhancing supply chain stability and competitiveness.Taking A-share listed companies from 2009-2021 as a sample,the paper finds that the closer the geographic and institutional distance between supply chains and shared auditors,the better the customer stability and the more durable the supply chain relationship.Further analysis finds that the synergistic effect of shared auditors on the supply chain is mainly reflected in the case of closer distance to clients,which is consistent with the current status quo where buyer's market dominates.In addition,the larger audit firms are more effective in leveraging supply chain synergies and improving supply chain performance.The results of the study provide new perspectives on supply chain management and shared auditors practices,which are of great theoretical and practical significance for enhancing the risk resistance and market competitiveness of supply chains.
