客户议价能力与供应商会计稳健性

Customers＇ Bargaining Power and Suppliers＇ Accounting Conservatism

由于存在信息不对称与报酬不对称问题,客户需要供应商会计稳健性更高并据此对供应商加以评估。本文以2007—2011年所有A股制造业上市公司为研究对象,实证结果显示：客户议价能力越强,客户越有能力要求供应商提高会计稳健性程度,供应商也愿意这么做以保障交易的顺利进行。进一步分析表明,专有化投资及产品独特性强化了客户议价能力对供应商会计稳健性的影响,而较高的行业集中度弱化了客户议价能力对供应商会计稳健性的影响。本研究有助于充分认识会计稳健性在契约关系中的作用,同时也有助于充分理解客户特征对企业行为的影响。

This paper investigates the effect of customers＇ bargaining power on suppliers＇ accounting conservatism,using data of corporate customers of Chinese A-share listed manu- facture companies from 2007 to 2011. Our results show that,those suppliers whose customers have greater bargaining power will report more conservatively. Furthermore, we find that, suppliers will react more strongly to customers＇ conservative demand when relationship-spe- cific investments exist or suppliers＇ products are unique,while the degree of reaction will de- crease to a lower extent due to a higher industry concentration of suppliers. Our findings provide insights into how a supplier＇s powerful customer affect its accounting conservatism and also help understand the role of accounting conservatism play on contracting relationships.
