摘要: 本文以2004-2014年沪深A股非金融行业上市公司为研究样本,结合企业竞争地位,系统分析并验证供应链集中度影响权益资本成本的作用机理及可能的传导路径。研究结果发现:供应链集中度越高,企业权益资本成本随之提升;经营风险是供应链集中度影响权益资本成本的一个中介路径,即企业较高的供应链集中度会加剧其面临的经营风险进而导致权益资本成本增加。较高的企业竞争地位能够弱化供应链集中度对权益资本成本的负面影响,且企业竞争地位是通过缓解企业的经营风险这条路径影响了二者之间的关系,即较高的企业竞争地位因其具有较强的抵御风险能力从而缓解了供应链集中度引发的经营风险,继而对供应链集中度与企业权益资本成本之间的正相关关系产生弱化作用。

Abstract: Taking 2004-2014 A-share non-financial industry listed company as a research sample, the paper systematically analyzes and verifies the mechanism of the influence of supply chain concentration on the cost of equity capital and the possible transmission path. The research results show that: the higher the concentration of supply chain, the higher the cost of corporate equity capital; the operational risk is an intermediary path in which supply chain concentration affects the cost of equity capital, that is, the higher concentration of supply chain in the enterprise will intensify its operational risks faced in turn lead to an increase in the cost of equity capital. The higher competitive position of enterprises can weaken the negative impact of supply chain concentration on the cost of equity capital, and the competitive position of enterprises affects the relationship between them by mitigating the business risk of the enterprise, that is, higher competitive position of enterprises has a strong ability to withstand risks, thus alleviating the operational risks caused by the concentration of supply chain, and then weakening the positive correlation between supply chain concentration and corporate equity capital costs.

Key words: competitive position of enterprise, supply chain concentration, operating risk, cost of equity capital
