Supply Management Under High Goal Incongruence: An Empirical Examination of Disintermediation in the Aerospace Supply Chain

Aftermarket sales and profits are becoming an increasingly important part of an original equipment manufacturer's (OEM) business model. Because replacement parts often do not require further manufacturing, OEMs act as intermediaries in the aftermarket. As with any intermediary, the OEM must concern itself with suppliers disintermediating its supply chain selling replacement parts directly to the OEM's customers. We frame supply chain disintermediation (SCD) as a principal–agent contracting problem between an OEM buyer and a supplier. Hypotheses relate contract conditions, goal incongruence, supplier capabilities and contract enforcement to SCD. The data are collected from the aerospace industry using a multimethod study, combining an Internet‐based survey with archival data. Causal modeling with structural equation modeling (SEM) shows general support for the hypotheses. Particularly, SCD is positively related to buyer–supplier goal incongruence. The agency model offers insights that differ from previous transaction‐cost‐based models of buyer–supplier relationships. OEM buyers with a lucrative aftermarket should consider aligning goals through incentives rather than relying entirely on economic hostages associated with specific assets.     

供应链管理对企业财务绩效的影响研究

文章选取我国2001-2006年间实施过供应链管理的上市公司前后共4年(从实施前一年到实施后两年)的数据作为样本,运用事件关联影响研究法并剔除行业均值的影响后进行实证研究以探究我国企业实施供应链管理的受益程度。实证结果显示:只有实施后第二年较实施前一年企业的现金周转期平均缩短了14.7天;管理和销售费用占比平均下降了1.01个百分点;营业利润率平均提高了2.49个百分点。其它业绩指标均没有显著的变化。从相关和回归分析的结果看,现金周转期的缩短导致管理、销售费用占比的下降,从而显著地驱动营业利润率的提高。本文的研究结果部分地回答了信息技术生产率悖论的问题,无论对学术界还是实务界均具有一定的现实意义。
