宏观经济政策如何影响客户集中度的库存管理效应

How Macroeconomic Policies Affect theInventory Management Effect of Customer Concentration

本文以2007-2010年我国制造业上市公司为样本,检验供应链下游客户对存货管理效率的影响,并进一步考察了宏观经济政策对二者的关系的影响作用。研究发现:(1)客户集中度越高,企业的存货管理效率越高;(2)"十一五"规划的支持会强化客户集中度对存货管理效率的促进作用;(3)对于非国有企业而言,"四万亿"计划出台后,客户集中度能够显著提高存货管理效率,而该计划出台前则不具有这种作用。本文的研究对我国生产型企业供应链及存货管理都具有一定的启示。

This Paper studies the association between the customer of downstream supply chain and the efficiency of inventory management,by using listed companies in manufacturing industry from 2007 to 2010. And we investigate the macroeconomic policy’s impact on the relationship of the two aspects. We find that(1) the higher the customer concentration,the better the inventory management efficiency;(2) the"11th Five-year Plan"will strengthen the positive correlation between customer concentration and inventory efficiency;(3) for the non-state-owned enterprises,after"Four Trillion"plan,customer concentration can significantly improve the efficiency of inventory management,while before the plan they do not have this kind of relationship. The conclusion contributes to the supply chain and inventory management of manufacturing enterprise.
