Blockchain technology provides us a new tool to solve the product traceability problem in supply chain management. This research focuses on the cross-border e-commerce context, to propose a blockchain-based framework, and develop a set of corresponding techniques and methods for achieving traceable products and transactions in supply chain management. A general blockchain-based product traceability framework is introduced. This framework is based on a cross-border e-commerce supply chain context, incorporating a series of blockchain-based models, including multi-chain structure model, data management model and block structure model. Several core methods and algorithms are also developed, such as information anchoring method, key distribution method, information encryption algorithm and anti-counterfeiting method. The framework, models and methods form a complete and comprehensive solution, which are evaluated by applying to several typical problems and attack cases. The case analysis results show that the framework, models and methods can successfully deal with key recover problem, and protect against clone attack, counterfeit tag attack and counterfeit product attack. The effectiveness, extendibility, security, implementation and governance issues of applying these solutions are also discussed. This research contributes to the theoretical and practical literatures on blockchain technology, cross-border e-commerce and supply chain management research fields. 相似文献

Blockchain technologies have captured the imagination of scholars, managers, and practitioners around the world. It is widely accepted by these actors that blockchain is not a buzzword, but a highly disruptive technology that is already remodeling the organizations and their supply chain business models. Despite the meaningful advance in the last years, blockchain applications regarding the operations and supply chain management (OSCM) are still in their infancy. Little is known about the role of blockchain in terms of operations traceability, as well in areas such as e-commerce, agriculture, public services, etc. Therefore, this Special Issue seeks to extend our understanding of blockchain applications in OSCM and how firms create and capture business value with blockchain. To this effect, this Special Issue will provide a well-articulated and in-depth discussion of the role of blockchain in creating value in the domain of OSCM. Specifically, it is expected that more light is shed on how blockchain integrates with and impacts new business models, transforms relationships, and improves performance and competitive advantage in OSCM. Also, the evolution of blockchain was reviewed in order to provide a strong background to the readers. The literature review was performed taking into account a bibliometric perspective of blockchain-related publications. The review supports the importance of this Special Issue by highlighting the urgent needs of this topic in this reputable journal. Finally, we provide future research directions and a guide for the papers presented in this Special Issue. 相似文献

As a new type of disruptive internet technology, blockchain technology is widely used as a technical support for enterprises to improve production processes and reduce costs. This paper reveals that existing research has only focused on the business process modelling and technology design process of a blockchain-based solution and has neglected analysis of the relationship between blockchain technology and enterprise operational capabilities based on actual data. Hence, this paper collects 50 listed blockchain technology enterprises in China and quantitatively analyses them. The results show that the expansion of the enterprise asset scale is a significant driving factor for implementing blockchain technology. In addition, this paper proves that implementation of blockchain technology has a positive impact on improving asset turnover rate and reducing sales expense rate. Based on the results of theoretical and empirical analysis, this paper provides some constructive suggestions for constructing blockchain projects in the future. 相似文献

Inter-organizational Systems (IOS) are network-enabled information systems that extend boundaries of an organization. There is a growing interest among researchers and practitioners to understand how the use of IOS enhances firm performance. In this study, we examine how IOS use impacts an organization’s supply chain management (SCM) capabilities and supply chain performance. Drawing on the resource-based view theory, we examine two mechanisms that are essential for enhanced supply chain performance: (a) efficient IOS external utilization regarding its networked partners and (b) the maximization of IOS organizational management capabilities in supply chain management. Using data from 193 respondents from various manufacturers and distributors of fast-moving consumer goods, we confirm all the hypotheses posited in the research model. The results demonstrate the dual effect of IOS use in improving operational supply chain performance, SCM capabilities, and the mediating role of SCM capabilities. We discuss contributions of the study to research and practice. 相似文献

The digitalization phenomenon is leveraging new relationship models through the entire supply chain network. In this outlook, blockchain is a cutting-edge technology that is already transforming and remodeling the relationships between all members of logistics and supply chain systems. Yet, while studies on blockchain have gained a relative pace over the recent years, the literature on this topic does not report sufficient research cases on blockchain adoption behavior at the individual level. The present study, therefore, aims to bridge this gap, notably by helping understand the individual blockchain adoption behavior in the logistics and supply chain field in India and the USA. Drawing on the emerging literature on blockchain, supply chain and network theory, as well as on technology acceptance models (TAMs), we have developed a model based on a slightly-altered version of the classical unified theory of acceptance and use of technology (UTAUT). The model being developed was then estimated using the Partial least squares structural equation modeling (PLS-SEM). As the model was eventually supported, the results obtained revealed the existence of distinct adoption behaviors between India-based and USA-based professionals. In parallel, the findings appear as a useful contribution to and a sign of progress for the literature on IT adoption, SCM, and blockchain. 相似文献

Blockchain technology is said to have a high disruptive potential and can do without an intermediary. Numerous contributions deal with its impact on and possibilities for logistics and supply chains. In this article, we use a multiple case analysis to develop an explanatory model for the interaction of actors in an operational supply chain involving blockchain technology. In addition, we show which intermediary tasks the blockchain could replace and what impact this would have on the industry logic. For this purpose, we analyze the status quo in practice based on a multiple case study with real use cases and find answers to our research questions. The findings of the paper include (1) insights into the impact of blockchain technology on the logistics industry, and (2) the implications and research questions related to blockchain technology and the impact of blockchain technology on business models. 相似文献

Permissioned blockchain utilized by any organization is commonly known as Enterprise Blockchain (EBC). EBC represents a popular investment option as enterprise system in the service industry. This paper aims at analyzing the perception of EBC among practitioners in service industry. As significant hype prevails about EBC usefulness in service industry, we examine if the perception of the usefulness of EBC among practitioners is borne out of knowledge of theoretical benefits of EBC, or is it borne out of the hype. A scale for measuring EBC benefits is developed. In order to test the hypothesized relationships, structural equation modelling (SEM) is used. We extend the concept of perceived usefulness from technology acceptance model for service supply chain management (SCM) and measure the perceived usefulness of EBC for six supply chain dimensions in the service industry. We examine if the service industry managers perceive EBC to be profitable based on the practical usefulness of EBC in various dimensions of service SCM. Moderating effects of 5 factors are analysed on relationships of our research model. This paper provides insights about the dimensions of service SCM, in which service industry practitioners perceive EBC to be useful and may contribute to increment in organization’s profitability. 相似文献

Proof-of-Work (PoW) is a common mechanism used to validate peer-to-peer transactions and maintain highly secured immutability of the blockchain. However, this mechanism has been criticized due to its inefficient use of computing resources and its limited usefulness. In this paper, we propose the Proof-of-Useful-Work (PoUW) as an alternative mechanism for transaction validation that puts the squandered computing resources to beneficial use. The main premise is to replace the mathematical puzzle, which constitutes a fundamental part of the Proof-of-Work mechanism, with NP-hard optimization problems whose solutions benefit the participants of the blockchain. We demonstrate its usefulness in the context of transportation. Accordingly, PoUW-based blockchain not only tracks, manages and validates transactions, but also optimizes transportation requests profiting its ecosystem. We describe the framework of the proposed PoUW along with the associated optimization model and the miner’s reward mechanism. 相似文献

Motivated by the seeming presence of the productivity paradox in China, this research revisits the question of how information technology (IT) affects firm performance. Leveraging the process-based view of IT, we establish a theoretical framework for the mediation factors for the relationship between IT capabilities and performance. Based on a survey of 127 companies in China, we find that a firm's management capabilities to manage both its internal and external business processes fully mediate the impact of IT on firm performance. The two management capabilities in this study are business-process management capability and supply-chain management capability. Our results show that only the coherent integration of IT capability with firm’s ability to optimize business processes and to improve management of supply chains can enhance firm performance. Firms should avoid the fallacy that IT investments are solely responsible for better firm performance. Based on our findings, we discuss the implications for research and practice. 相似文献

This study investigates the impact of information technology (IT) on supply chain agility measured by the ability to sense and respond to market changes, and the impact supply chain agility has on firm performance. Data were collected from supply chain executives at 193 U.S. manufacturing firms. The results suggest that IT improves the supply chain's ability to sense market changes by improving the adequacy, accuracy, accessibility, and timeliness of the information flows among members of the supply chain. IT also increases the supply chain's ability to respond to market changes by reducing the cost, and improving the quality and timeliness of developing and executing coordinated plans to respond to market changes throughout the supply chain. Importantly, the results indicate that enhanced supply chain agility has positive impacts on the firm's sales, market share, profitability, speed to market, and customer satisfaction. 相似文献

This research aims at deepening the understanding of the effects of information systems on supply chain operations, and to find the level and direction of the relationship between Enterprise Resource Planning (ERP) and Knowledge Management (KM) in the context of operational and financial performance. Essentially, this study emphasizes the explanation of the complementary relationship between ERP and KM. Therefore, the mediating effect of KM is also analyzed. Using a survey method, 163 responses are collected from Turkish manufacturing companies which operate in a variety of industries. A structural equation modelling (SEM) is used to test both the reliability and validity of measurement and the structural path model. The results show that ERP has no significantly positive effect on operational performance, but it is a precedent of KM. Moreover, results also show that KM affects operational performance positively and it has a mediating effect for the relationship between ERP and operational performance. Lastly, the path analysis shows that operational performance is positively associated with financial performance. 相似文献

The purpose of this paper is to understand the key issues faced by supply chain (SC), current strategies and trends of this field, understand IT technical issues and implication for business performance and how IT can foster IM and help sort out the SC problems. Studies from different and recognised authors are reviewed, compiled and analysed in two aspects. First, a detailed picture of SC trends, issues and strategies is depicted. After, main concerns about IT, such as its goals, importance, pitfalls, and features are presented. Moreover, current applications of IT in SC and critical problems and competitive advantages in the IT implementation in the supply chain management's competitive priorities are detailed. SC's new configuration and reality have increased the level of uncertainties and risks present in supply chain activities. Some strategies to mitigate these problems have undermined the SC efficiency. Therefore, a new strategy that uses IT to make SC more robust and resilient should be developed. As a holistic problem, a modelling approach (SDDES) should be used as a tool to support this study. 相似文献

Supplier reliability and order fulfilment performance are usually assessed using a perfect-order calculation. Information management of perfect-order estimation is frequently reduced to expert estimates and to the multiplication of probabilities of failure-free performance of some logistics operations. Moreover, perfect-order estimation is calculated without consideration of supply chain structure, possible combinations of failures, and operational policies (e.g., safety stock levels and alternative transportation routes). As a result, the existing methods frequently provide different estimates for the same statistics and cannot be consistently used in the allocation of companies’ resources to improve the order fulfilment process. This paper considers different variants of probabilistic assessment of a perfect order and proposes an approach to assess the impact of changes in parameter probabilities and number of parameters on the value of a perfect order. The proposed models are based on an analytical approach using discrete distributions of random variables. We illustrate the applicability of our approach to several numerical examples to confirm the adequacy of the proposed method. Our approach can be immediately applied in practice to assess supply and order fulfilment process reliability and to evaluate the effectiveness of various operational policies (safety stock levels or modes of transportation) to achieve some planned values of a perfect order in the supply chain. 相似文献

This study examines the literary corpus on the role and potential of blockchain technology in promoting gender equality through the lens of new technology-oriented corporate governance models. It investigates if and how corporate governance models can include blockchain technology to add value to gender equality and inclusion processes, in line with Sustainable Development Goal (SDG) 5. A bibliometric analysis of a database—containing 127 articles, 4 United Nations reports, 3 European institutions’ reports, 1 International Labour Office report, 1 World Economic Forum report, and 4 industry reports useful to our analysis—was conducted from 1990 to 2021, to provide a map of the knowledge generated and circulated by the literature. This study offers insights into publication activities, essential topics, citation trends, and the status of collaborations between contributors to previous research and aggregated contributions to the area of blockchain technology studies. Furthermore, the study offers a retrospective analysis of the content published in the blockchain technology field. The findings indicate that field research has focussed primarily on blockchain’s economic and financial attributes but not on social potential. This study emphasises the implementation of blockchain technology to manage gender equality and inclusion processes by orienting corporate governance models towards social and sustainable values. 相似文献
