The supply network becomes more fragile as it becomes more complex, affecting the core firm’s performance. While previous research on supply network complexity existence paradox. Therefore, to study the nature of supply network complexity, this paper divides the supply chain complexity utility into positive and negative valences based on the valence framework and divides supply chain complexity into supply base complexity, customer base complexity, and logistics base complexity. Based on the trustworthiness and transparency characteristics of blockchain technology, this paper investigates how to use blockchain technology to reduce the negative valence of supply chain complexity while adapting to or improving the positive valence to improve enterprise competitiveness and supply chain sustainability. As a result, the focus of this paper is on how to better manage supply chain complexity using blockchain technologies to increase supply chain sustainability and viability.
Yet we cannot guarantee that the information that is shared among supply chain entities is correct. Blockchain has been proposed to solve the lack of trust in financial transactions. This paper examines whether blockchain enables entities in the supply chain to trust the shared information regarding the physical flow. A conceptual framework is proposed to explain how and why supply chain entities can trust the shared information when using blockchain. This paper deepens our knowledge of the use of blockchain in the supply chain. It also provides valuable insights to those working in information and supply chain management related-fields.
With the deepening of globalization and the improvement of the fineness of production division and cooperation, various forms of suppliers coexist, and the supply chain network becomes complex and fragmented. Traditional supply chain management mode and purchasing mechanism cannot respond to the changes of the times in time, and enterprises and suppliers cannot connect. As a new type of financial service, supply chain finance plays an important role in solving the financing difficulties and expensive problems of SMEs. However, in recent years, traditional supply chain finance has encountered many problems, and it has gradually become a trend to empower traditional supply chain finance with blockchain technology. This paper proposes a blockchain supply chain financing risk assessment and behavior prediction algorithm. By analyzing the development status of supply chain business, it puts forward corresponding preventive measures to effectively improve the efficiency of supply chain financing. Firstly, the paper puts forward the double‐chain management system and constructs the double‐chain management architecture and operation flow; Thirdly, the weighting method of enterprise financing risk evaluation index based on variance homogeneity test is put forward to explain; Finally, five enterprises are tested on the data set, and the performance of TPR, FPR, Precision, Recall, F‐Measure, and Accuracy is compared. Different enterprises have the problem of supply chain financing risk.

Blockchain technology is promising toward transforming conventional construction practices to improve collaboration and integration management in engineering-construction projects. The factors affecting the adoption of blockchain technology from the different stakeholder perspectives, however, have not been thoroughly investigated. Following the theory of planned behavior (TPB) and regulatory focus theory (RFT), this study explores the formation mechanisms underlying blockchain technology adoption from a multi-stakeholder perspective. The model was tested through partial least squares-structural equation modeling (PLS-SEM) and the fuzzy-set qualitative comparative analysis (fsQCA) method using data collected from Chinese construction practitioners. PLS-SEM results indicate that institutional pressures, perceived functional benefits, and behavioral control can directly drive blockchain adoption. Although perceived symbolic benefits do not directly affect blockchain adoption, their indirect effects on adoption are fully mediated by adoption intention. The PLS multi-group analysis found multiple path differences among stakeholders. The fsQCA results show that no single factor or its negation is the necessary condition to trigger blockchain technology adoption. The configuration analysis results show four new configurations that trigger the adoption of blockchain technology by owners, contractors, and consultants. This study not only enriches the related research on TPB and blockchains but also helps technology promoters to use strategies tailored to different stakeholders in theory and practice to improve blockchain technology adoption.
As a temporary facility, scaffolding has an essential role in providing a work environment at height in the construction industry. According to the Occupational Safety and Health Administration (OSHA), approximately 65% of laborers work on scaffolding. Scaffolding work information needs to be effectively managed with reliability to provide a safe environment. However, managing information of the scaffolding work process remains challenging in forgery risk and manual verification. Blockchain has been widely introduced as an accountable and efficient information management solution. This study presents a blockchain-based system for scaffolding work to grant reliability and efficiency of information management. The system is developed to secure applicability by considering three aspects: (1) optimal blockchain platform regarding characteristics of scaffolding work; (2) storage method to address the hindrance of blockchain; (3) information needed to be compared for verifying adequacy. The detailed configuration and process model for the system is categorically presented, and validated via a case study. The case study confirmed that the system was able to store the information in the block smoothly, verify the information using the smart contract successfully, and remain the block size constant by using off-chain. The proposed system has the potential of practical applicability and could contribute to mitigate potential safety risks associated with inadequate scaffolding work management. Furthermore, the proposed system development flow can be leveraged as a guideline to extend blockchain applications to diverse areas in the construction domain.

Abstract Despite the increasing proliferation of deploying the internet of things (IoT) in the global value chain (GVC), several challenges might lead to a lack of trust among value chain partners, for example, technical challenges (i.e., confidentiality, authenticity, and privacy); and security challenges (i.e., counterfeiting, physical tampering, and data theft). In this study, we argue that blockchain technology (BT), when combined with the IoT ecosystem, will strengthen GVC and enhance value creation and capture among value chain partners. Therefore, we examine the impact of BT combined with the IoT ecosystem and how it can be utilized to enhance value creation and capture among value chain partners. We collected data through an online survey, and 265 U.K. Agri‐food retailers completed the survey. Our data were analyzed using structural equation modeling. Our finding reveals that BT enhances GVC by improving IoT scalability, security, and traceability combined with the IoT ecosystem. Moreover, the combination of BT and IoT strengthens GVC and creates more value for value chain partners, which serves as a competitive advantage. Finally, our research outlines the theoretical and practical contribution of combining BT and the IoT ecosystem.

Abstract This study advances theoretical insights into blockchain adoption in the context of global value chains from a transaction cost theory perspective. The research has adopted an exploratory qualitative approach using the Netnography method to scrutinize the case of TradeLens—a thriving blockchain‐enabled ecosystem that Maersk and IBM jointly developed. This study applies textual and audiovisual data from company websites and social media. Our findings indicate blockchain technology's salient and strategic relevance in streamlining business processes, improving efficiency, enhancing visibility, transparency, and traceability for value creation in the global value chains. This investigation supports the notion that blockchain, as a disruptor, will transform global trade with the digital tools to share real‐time information and collaborate security to reduce search and information cost, policing and enforcement cost in global economic transactions and administrative friction in trade. In contrast, the bargaining cost will increase if the information for the transaction is hard to verify where human actor intervention will be required, implying relatively higher designing costs in codifying the agreements in smart contracts.

The scientific community has become concerned about the impact of blockchain technology as a motivational tool in the COVID-19 era. Since the beginning of the pandemic, the number of scientific articles published in this field has been increasing, making it highly desirable to carry out a bibliometric study to identify research efforts. Therefore, the aim of this work was to conduct a literature review of blockchain and COVID-19 technology in the field of Business Management to identify recent lines of research. To do so, we used a text mining technique on a corpus composed of 37 articles in the Web of Science database. The results obtained clearly show 3 distinct clusters. The first represents the blockchain technology framework in organizations and stakeholders in which the research methodology in artificial intelligence is very important. The second shows the need to take into account business sustainability caused by COVID-19. The third indicates the impact of the pandemic on the supply chain industry.
Supply chain management (SCM) is a core corporate activity responsible for moving commodities and services from one point to another through various stakeholders. The traditional SCM is based on a centralized approach managed at the central headquarter, and all other sub-offices get instructions from the main office. Some major issues with present SCM systems are security, transactional transparency, traceability, stakeholder involvement, product counterfeiting, additional delays, fraud, and instabilities. Blockchain (BC) emerges as a technology that can manage the data and build trust efficiently and transparently. It can also aid in transaction authorization and verification in the supply chain or payments without a third party. To address the present SCM issues, BC technology is a feasible solution. Motivated by the aforementioned considerations, in this paper, we present a survey on the adoption of BC in SCM. This paper undertakes a comprehensive analysis of the literature on BC characteristics, implementations, and business consequences in various SCM. This Blockchain-centered study, in particular, discloses the research state and delineates future research directions by studying and analyzing 97 up-to-date publications highlighting BC’s supply chain uses. Transparency and traceability, information sharing, product anti-counterfeiting, and building trust are the major aspects propelling BC’s implementation in SCM. Further, we analyzed various applications of SCM in which BC can be used as a probable technology to secure all transactions. Then, we have highlighted open issues and research challenges for adopting BC technology in SCM that open the doors for beginners eager to start work in this amazing area.
This chapter considers the advances in governance and how this frames crisis management and product recalls in food supply chains. Effective food recalls following a food safety or legality related incident are supported by traceability systems that range from being paper based to those that apply the newest technology. This chapter is written to consider the value of Distributed Ledger Technologies (DLTs) for the improvements in food supply chain governance structures that are especially tested during product recalls. The focus is on identifying advantages of Blockchain systems within public-private partnerships (PPPs) for food governance. There is a great potential to reduce information asymmetry, which is a key barrier to supply chain development, innovation and efficiency, and effective crisis management and product recalls with the use of DLTs including Blockchain. PPPs for supply chain governance can deliver value at the supply chain and wider stakeholder level including developing Blockchain consortia to improve overall efficiency and integrity in data collection, storage and sharing.
