PurposeImplementing just-in-time (JIT) practices on the supplier side is a common practice to streamline procurement and production planning in realization of cost efficiency and lead time reduction. However, it is little known how supplier JIT is related to firm flexibility performance and what factors may facilitate the relationship. This study aims to investigate the effects of supplier JIT on flexibility performance and explore the moderating impacts of advanced manufacturing technology (AMT) and human resource empowerment (EMP).Design/methodology/approachThis study applies hierarchical linear regression analysis to test the proposed model based on data collected from 213 manufacturing firms in China.FindingsThe results revealed a negative influence of supplier JIT on flexibility performance. However, the adoption of AMT and EMP reconciles the conflict between supplier JIT and flexibility performance. Besides, the results indicate the positive effects of AMT and EMP on flexibility performance.Originality/valueThis study contributes to supply chain JIT literature by providing a holistic view to understand the structural relationships between supplier JIT, AMT, EMP and flexibility performance.

PurposeThe fast-growth of tourism industry in sub-Saharan Africa (SSA) has increased supply chain activities that harm the environment. Although there are some studies which have investigated the impact of tourism supply chain on sustainable performance, little is known on the side of SSA. Based on the natural resource-based view (NRBV), this study examines the effects of green purchasing, green packaging and reverse logistics on sustainable performance in SSA.Design/methodology/approachThis study applies the structural equation modeling (SEM) to test the conceptual model based on the data collected in mid of 2020 from 167 firms in tourism industry in Tanzania.FindingsThe results demonstrate that green purchasing (GP) has positive effects on environmental performance (EVP) and social performance (SCP). Green packaging (GPa) has positive effects on EVP but no significant influence on SCP. Also, reverse logistics (RL) has positive effects on SCP but no significant influence on EVP. Besides, both EVP and SCP positively influence ECP and mediate the relationships between GP, GPa and RL with ECP.Originality/valueThis study provides a novel framework in sustainable tourism supply chain literature by empirically investigating the relationship between tourism supply chain practices and sustainable performance in SSA.

PurposeThe relationship between just-in-time (JIT) and supply chain disruption risk is unclear from the existing literature. This paper aims to investigate the impact of supplier JIT and customer JIT on supplier disruption risk (SDR), internal disruption risk (IDR), and customer disruption risk (CDR) and explore the moderating role of supply chain centralization.Design/methodology/approachBased on survey data collected from 213 manufacturing firms in China, this study employs structural equation modeling with SmartPLS 3.0 to test the main proposed model and applies an ordinary least square regression to test the moderating effect.FindingsThe results demonstrate that supplier JIT is positively related to SDR and negatively associated with IDR. Customer JIT is positively associated with CDR but has no significant effect on IDR. The results also show that SDR and CDR lead to IDR and mediate the relationship between supplier JIT, customer JIT, and IDR. In addition, supply chain centralization amplifies the positive impacts of supply chain JIT on SDR and IDR.Originality/valueThis study makes two main contributions. First, the study provides a comprehensive analysis of the relationship between supply chain JIT and disruption risk. Second, the study addresses that implementing JIT in a supply chain with a centralized decision-making structure leads to a higher level of disruption risk.
