环境不确定性、客户集中度与企业生产效率——基于供应链客户关系视角和门槛效应的研究

Environmental Uncertainty,Customer Concentration and Enterprise Production Efficiency:A Study Based on the Perspective of Supply Chain Customer Relationship and Threshold Effect

在百年未有之大变局背景下,供应链客户关系对企业生产效率的影响值得深入探索。基于此,研究以2011年—2020年A股上市公司为对象,基于交易成本理论和资源依赖理论实证分析企业客户集中度对企业生产效率的影响。检验发现:客户集中度对企业全要素生产率存在显著抑制作用,且环境不确定性增强了这种抑制作用;客户集中度可以通过负向影响企业的营销能力来抑制企业生产效率;营销能力在客户集中度与企业生产效率的负向关系中存在单一门槛;异质性检验发现,在环境不确定性较高、客户稳定性较低的条件下,以及在非国有企业中,客户集中度对企业生产效率的抑制作用更加显著。

Under the background of unprecedented changes in a century,the impact of supply chain customer relationship on enterprise production efficiency is worthy of in-depth exploration.Therefore,this paper takes A-share listed companies from 2011 to 2020 as the research objects,and empirically analyzes the impact of enterprise customer concentration on enterprise production efficiency based on transaction cost theory and resource dependence theory.The test shows that customer concentration has a significant inhibitory effect on total factor productivity of enterprises,and environmental uncertainty enhances this inhibitory effect;Customer concentration can inhibit the production efficiency of enterprises by negatively affecting the marketing ability of enterprises;Marketing ability has a single threshold in the negative relationship between customer concentration and enterprise production efficiency;The heterogeneity test found shows in the higher environmental uncertainty,lower customer stability and non-state-owned enterprises,customer concentration has a more significant inhibitory effect on enterprise production efficiency.
