Sustainability in Global Supply Chains: A Study on the Impact of Distributed Ledger Technology on Ethical Sourcing and Consumer Trust

Abstract

Introduction: The study examined how Distributed Ledger Technology (DLT) can play a role in business ethics and how the ethical conduct of business can help consumers have more confidence in the global supply chain. It further explored how the adoption of Ethical Sourcing Practices (ESP) mediates the relationship between DLT adoption and consumer confidence in the Saudi Arabian context. Methods: A purposive sampling approach was followed in accordance with a positivist approach. In order to gather the information among 355 respondents, an online survey was distributed, and the data have been analysed with the help of partial least squares structural equation modelling (PLS-SEM) in SmartPLS 4.0. Results: The findings of the PLS-SEM established that DLT significantly predicted Ethical Sourcing Practices (0.641, p < 0.001) whereas ethical sourcing practices also had significant and positive impact on perceived consumer trust (0.518, p < 0.001). The direct effect of DLT on perceived consumer trust was significantly positive (β = 0.325, p < 0.001). The model explains 41% of ESP and 59% of trust. Additionally, a significant indirect effect of DLT on perceived consumer trust via ethical sourcing practices was confirmed, indicating partial mediation (β = 0.331, p < 0.001). Conclusion: This research combined model that correlates DLT adoption, ethical sourcing practices, and perceived consumer trust using the TOE and signalling theories. It uses data on multi-industry supply chains from multi-industry surveys (Saudi Vision 2030) to illustrate the capacity of blockchain-enabled sourcing capabilities and turn it into a trust gain. The research involves the cross-sectional survey data, which would allow finding statistical correlations but would not allow to establish the causality. Additionally, the results may not apply to all individuals in the industry.
