精益库存管理对企业绩效的影响研究——来自中国制造业上市公司的实证检验

The Impact of Lean Inventory Management on Firm Performance——Empirical Evidence from Chinese Listed Manufacturing Firms

本文以2009-2014年中国制造业上市公司为研究样本,通过构造Panel Data模型,实证检验了精益库存管理对企业绩效的影响。结果表明:中国制造业上市公司库存管理对企业绩效提升具有显著的促进作用,深入实施精益库存管理的企业绩效与一般企业之间存在显著差异,且深入实施精益库存管理的企业绩效更高。精益库存管理与企业绩效之间呈倒U形关系,存在精益库存管理的适度区间,适度实施精益库存管理对企业绩效的提升作用最为有效。进一步研究发现,精益库存管理对企业绩效的影响具有一定行业差异性,行业规模、毛利率是影响行业差异的主要因素。

Based on the Chinese manufacturing firms listed in the period of 2009 to 2014, we use Panel Data models to verify the impact of lean inventory management on firm performance. The results indicate that inventory management has a positive impact on firm performance. There is a significant difference between firms with deep lean inventory management and firms without that, and firms with deep lean inventory management have higher level of performance. There is an inverted U shape relationship between lean inventory management and firm performance, and it is advised that there is an optimal lean inventory management interval range effective for firm performance. And the further results indicate that the impact of lean inventory management on performance varies across industries, and industry scale and gross margin are the main causes of industry difference.
