A theory of purchasing's contribution to business performance
提出采购能力与业务战略的匹配程度决定了采购对业务绩效的贡献，并通过141家工业企业的实证分析支持这一观点。
Abstract Although the strategic importance of purchasing has been acknowledged in recent years, few studies analyze its contribution to business performance. The alignment of the purchasing function with business strategy is essential, but previous work links better performance with the implementation of specific purchasing practices. This article develops a different approach focused on purchasing capabilities rather than purchasing practices and proposes that purchasing's contribution to business performance depends on the degree to which purchasing capabilities fit with and support the business strategy. By adapting the Theory of Production Competence to the purchasing context, this article distinguishes two levels of fit: between purchasing strategic objectives and purchasing capabilities, defined as “purchasing efficacy,” and between business strategy and purchasing strategic objectives, which is viewed as an immediate consequence of the strategic integration of purchasing. The interaction between both levels of fit influences business commercial and financial performance, and an empirical analysis of 141 industrial companies supports this proposition.
