Abstract Continuous supplier selection, evaluation and reselection are among buying firms’ key processes to improve their overall performance. This paper aims at increasing knowledge on effective and dynamic supplier evaluation and management by answering the following research question: Do performance decomposition technique and real option theory represent appropriate mechanisms to understand structural change in supply chain and subsequent performance improvements? By taking insights from productivity dynamics in economics literature and real options theory from strategic investment context, we apply a method to measure buying firm’s overall supply chain performance through reallocation of purchases among exiting, surviving, and entering suppliers based on their past performance. The method is tested and illustrated with the case of a Finnish contractor and its 535 suppliers in 269 construction projects during 2013-2016. This study provides new insights into the dynamic business relationships of a large buyer in an uncertain environment where supply chain performance is improved through continuous changes in the supplier network. The novelty of this study lies in adopting concepts from productivity decomposition literature in microeconomics in the context of supplier selection and management to quantify the overall performance development of all suppliers, and break it down to the performance components of exiting, surviving, and entering suppliers as well as reallocation of purchases among survivors. Furthermore, real options theory helps in interpreting the entering, surviving, and exiting supplier groups as real options exercised, maintained, and abandoned, respectively.

对供应商的有效采购再分配：来自生产力动态和实物期权理论的见解

摘要 持续的供应商选择、评估和重新选择是采购公司提高整体绩效的关键过程。本文旨在通过回答以下研究问题来增加有关有效和动态供应商评估和管理的知识：绩效分解技术和实物期权理论是否代表了理解供应链结构变化和后续绩效改进的适当机制？通过从经济学文献中的生产力动态和战略投资背景下的实物期权理论中获取见解，我们应用一种方法来衡量购买公司的整体供应链绩效，通过根据过去的表现在退出、幸存和进入供应商之间重新分配采购。在 2013-2016 年期间，芬兰承包商及其 535 家供应商在 269 个建设项目中的案例对该方法进行了测试和说明。本研究为大买家在不确定环境中的动态业务关系提供了新的见解，在该环境中，供应链绩效通过供应商网络的不断变化而得到改善。本研究的新颖之处在于，在供应商选择和管理的背景下，采用微观经济学中生产力分解文献中的概念来量化所有供应商的整体绩效发展，并将其分解为退出、幸存和进入供应商的绩效组成部分。以及在幸存者之间重新分配购买。此外，实物期权理论有助于解释进入、生存、
