库存效率与客户集中度关系研究——基于中国上市公司分析

Research on the Relationship between Inventory Efficiency and Customer Concentration——An Analysis Based on Chinese Listed Companies

本文基于中国深圳交易所296家制造业企业2015—2017年3年间共888个数据研究客户集中度对库存效率的影响。对于库存效率,本文采用存货、存货周转率以及库存持有率来表示。控制变量采用了销售增长率等8个指标。在实证过程中,本文对样本进行了回归分析,结果表明对于全样本和盈利企业来说,客户集中度对存货有显著的负向影响,对于存货周转率有正向影响,对于库存持有率有微弱负向影响;对于主板和创业板企业来说,客户集中度对存货和库存持有率都有负向影响,而对于存货周转率有正向影响;在亏损企业中,客户集中度对存货和库存持有率都有微弱正向影响,对于存货周转率有负向影响。本文研究对于制造业企业进行库存管理时有一定的现实意义。
