信息共享程度对我国服装供应链库存成本的影响

The Impacts of Information Sharing Degree on Chinese Apparel Supply Chain Inventory Cost

我国服装行业库存水平近年逐渐恶化,库存问题成为该行业发展的重要瓶颈。信息共享被认为是有效解决该问题的方法之一。然而目前国内文献对我国服装行业信息共享的定量研究较为缺乏;同时国内外对信息共享的普适研究也多集中于比较共享与不共享信息的影响,鲜有文章研究信息共享程度对供应链绩效的影响。本文通过建立信息共享量化模型分析以下三种情况对服装行业供应商库存水平及成本的影响:(1)共享需求统计信息,(2)共享实时需求信息,(3)共享需求及市场信息。本文研究表明,共享实时需求信息比共享需求统计信息能有效降低供应商库存水平及成本;而额外共享市场信息,能增加供应链柔性,提高其应对市场不确定性的能力。本文研究信息共享程度对服装行业供应链的影响,旨在降低我国服装供应链高库存水平,并为我国服装企业信息化及品牌建设提供管理启示。

The inventory level of Chinese apparel industry has deteriorated a lot in recent years , and high invento-ry has been the bottleneck of the development of apparel companies .Information sharing is recognized as one of the effective methods to resolve this problem .However , there lacks quantitative studies addressing information sharing in Chinese apparel supply chain .Most of the existing literature to investigate information sharing focus on the impacts of sharing information or not , rather than how the sharing degree affects supply chain performance . This paper builds quantitative model to analyze three scenarios in apparel industry： （ 1 ） sharing demand statis-tics, （2）sharing timely demand information , （3） sharing demand and market information .This paper shows that sharing timely demand information can reduce supplier ’ s inventory level and cost .Furthermore , sharing market in-formation on top of demand information can enhance the supply chain flexibility and the ability of dealing market uncertainty .This paper may shed some new light on managing high inventory level of Chinese apparel supply chain , and provide some managerial insights on the informationization and brand development for the practitioners .
