摘要/Abstract

摘要： 实现客户集中度与会计信息质量的统筹兼顾对于优化稳定产业链供应链具有重要意义。本文以2007—2020年沪深A股上市公司为研究样本,立足于客户角色动态转变的视角,探析客户集中度对会计信息可比性的动态影响与作用机制。结果表明,客户集中度与会计信息可比性之间表现为先扬后抑的倒U型关系,阈值前客户集中度发挥“圈外监督”效应,促进会计信息可比性增加;阈值后客户集中度呈现“圈内协同”效应,降低会计信息可比性。基于供应商管理层策略性行为视角的中介效应检验发现,信息不对称程度和财务杠杆水平是客户集中度影响会计信息可比性的重要途径。

Abstract: It is of great significance to optimize and stabilize the supply chain of the industrial chain to achieve the overall consideration of customer concentration and the accounting information quality. Taking the A-share listed companies in Shanghai and Shenzhen from 2007 to 2020 as the research sample and based on the perspective of the dynamic transformation of customer roles, this paper explores the dynamic impact and mechanism of customer concentration on the comparability of corporate accounting information. The research shows that there is an inverted U-shaped relationship between customer concentration and the comparability of accounting information. Before the threshold, customer concentration plays a role of “outside supervision” to promote the growth of the comparability; After the threshold, the customer concentration presents the “intra circle synergy” effect, reducing the comparability. Based on the intermediary effect test from the perspective of strategic behavior of supplier management, it is found that the degree of information asymmetry and the level of financial leverage are important ways for customer concentration to affect the comparability of accounting information.

Key words: Customer Concentration, Comparability of Accounting Information, Information Asymmetry, Financial Leverage, Inverted U-shaped Relationship
