Abstract

Shocks caused by COVID-19 pandemic have compelled manufacturers to decrease their reliance upon just-in-time (JIT) and embrace a more just-in-case (JIC) approach. This study clarifies the right configurations of JIT and JIC under low/high upstream and downstream shocks. Drawing upon contingency theory and configuration theory, a framework is developed to differentiate configurations of JIT/JIC under low/high magnitude SC shocks. Survey data from China's manufacturing industry, which experienced SC shocks due to COVID-19, are analysed by regression and sub-group analyses. The results show that only upstream shocks have a negative impact on operational performance. The effect of JIC (but not JIT) on operational performance is strengthened by upstream and downstream shocks. When shocks are high, increasing JIC is effective only when JIT is low. These empirical findings demonstrate that manufacturers can improve operational performance by emphasising JIC models under high SC shocks. Those with high JIT benefit from low JIC under low shock settings.

当供应链冲击增加时，及时生产和及时交货的正确配置是什么？

COVID-19 大流行所造成的冲击迫使制造商减少对准时制（JIT）的依赖，而更多地采用个案制（JIC）方法。本研究阐明了在低/高上下游冲击下 JIT 和 JIC 的正确配置。本研究借鉴权变理论和配置理论，建立了一个框架来区分低/高SC冲击下的JIT/JIC配置。本文通过回归分析和分组分析，分析了因 COVID-19 而受到 SC 冲击的中国制造业的调查数据。结果显示，只有上游冲击会对运营绩效产生负面影响。上下游冲击加强了 JIC（而非 JIT）对运营绩效的影响。当冲击较大时，只有当 JIT 较低时，提高 JIC 才会有效。这些实证研究结果表明，在高 SC 冲击下，制造商可以通过强调 JIC 模式来提高运营绩效。在低冲击环境下，JIT 高的企业可从 JIC 低的企业中获益。

期刊介绍： The International Journal of Production Economics focuses on the interface between engineering and management. It covers all aspects of manufacturing and process industries, as well as production in general. The journal is interdisciplinary, considering activities throughout the product life cycle and material flow cycle. It aims to disseminate knowledge for improving industrial practice and strengthening the theoretical base for decision making. The journal serves as a forum for exchanging ideas and presenting new developments in theory and application, combining academic standards with practical value for industrial applications.
