Abstract: From the perspective of the supplier, this paper matches the data of listed companies and their listed customers, examines the impact of listed customers' ownership concentration on the relationship-specific assets investment of the supplier corporation. It is found that the relationship-specific assets investment level of the supplier corporation decreases significantly with the increase of the customer ownership concentration. Further analysis shows that the above impact becomes more significant when the customers have a higher separation rate between the control right and the cash flow right and a lower degree of equity checks and balances, and when the suppliers have a lower bargaining power and greater difficulty in supervision caused by geographical distance. The above findings indicate that customers' ownership concentration has caused its major shareholders' agency problem (tunneling effect) and has led supplier corporations to reduce their relationship-specific assets investment.

摘要: 本文通过上市公司(供应商)与其上市客户的数据匹配,理论分析与实证考察客户股权集中程度对供应商关系专用资产投入的影响。研究发现,随着客户股权集中度的上升,供应商关系专用资产投入显著下降,支持股权集中引发的大股东“掏空效应”。进一步分析发现,随着客户大股东两权分离度的上升,股权制衡程度下降,以及供应商议价能力下降与地理距离增加带来的监督难度增加,上述负向影响表现得更为显著,表明客户股权集中引发的大股东代理问题(“掏空效应”)抑制了供应商关系专用资产投入。
