Abstract

During the onset of COVID, one of the major challenges that various companies started facing was poor supply chain resilience (SCR). Number of firms could not survive due to the poor response of their supply chains and even more struggled hard to keep their supply chains afloat. Practitioners, and researchers started arguing that implementation of blockchain technologies to manage supply chains, blockchain based supply chain (BCSCM), could be one of the viable solutions to the problem of resilience. Despite of having anecdotal evidence on the impact of blockchain base supply chain on various forms of SC resilience, there was void of scholastic literature clarifying as to how it improves SC resilience directly and through other essential strategies like SC mapping and channel integration. Against this scenario, present study aims to explain the impact of BCSCM on supply chain resilience. The study also examines the roles of supply chain mapping and channel integration (CI) in the association between blockchain based supply chain management and supply chain resilience. The study took the case of Malaysian Electrical and Electronics Industry, one of the largest contributors to Malaysian exports and GDP. A close-ended questionnaire was sent to 465 E&E sector firms for the purpose of data collection. As a result, 261 filled questionnaires were received out of which 247 fulfilling the set criteria were considered for final data analysis. Afterwards, Partial Least Square Structural Equation Modelling (PLS-SEM) was applied to test the modelled relationships. Findings of the study revealed a significant positive impact of BCSCM on supply chain resilience (SCR.) Further, the mediating role of SC mapping and channel integration between BCSCM and SCR was confirmed. Based on the findings of the study, we recommend policy makers to infuse the BC technology in upgrading the E&E sector’s supply chains to make them resilient. This will also improve the integration among the three streams of supply chain (upstream, midstream, and downstream) which in turn can improve SC resilience. Testing the impact of BCSCM directly and indirectly, through SC mapping and CI, is one of the prime contributions of this study. The findings of the study can provide key guidelines to improve the supply chain resilience of the firms especially in E&E sector
