The present study constructs a remanufacturing supply chain framework that encompasses both manufacturer and retailer. We conduct an in-depth investigation into the influence exerted by blockchain platforms in the supply chain, in response to carbon reduction challenges initiated by manufacturers. By introducing parameters such as the proportion of joint emission reduction investment costs and blockchain unit verification fees, we perform a comprehensive analysis of the effects produced by consumer sensitivity and blockchain platforms on sales prices, recycling prices, carbon emission reduction, market demand, amount of recycled, and profits under different emission reduction modes. Research has revealed that irrespective of whether the manufacturer adopts blockchain platforms, wholesale prices, retail prices, carbon emission reduction, market demand, manufacturer's profit in the joint emission reduction model are always higher than those in individual emission reduction model, while recycling prices and amount of recycled remain unchanged. With retailer's share of the carbon reduction investment cost kept within an appropriate range, both profits of retailer and supply chain increase under joint emission reduction model. When a manufacturer introduces blockchain technology platforms, unit verification fees only affect wholesale prices and have no impact on retail prices, recycling prices, carbon emission reduction, and profits.

In the context of the digital economy, especially with the application of blockchain in recent years, it has had a profound impact on the pharmaceutical manufacturing supply chain. Based on this, this study focuses on the strategic choices of channel governance models for medical manufacturing enterprises and has constructed three pharmaceutical supply chain production models: the benchmark wholesale price model S, the profit-cost sharing coordination model C, and the blockchain occupation model E. The research found that the coordination model C has the greatest advantage when cost sharing is sufficient and profit distribution is reasonable, which can effectively motivate channel members to expand the market scale and ultimately achieve a win-win situation. The benchmark model S plays an important coordinating role when the market risk is high. The occupation model E can significantly enhance the market dominance when the enterprise has strong blockchain technology capabilities, but it will also cause channel conflict risks. In addition, this study provides theoretical basis for achieving a positive synergy loop in terms of market prices, services, blockchain investment, and sales volume, and provides strong guidance for the strategic management choices of supply chain members.

Chronic information asymmetries in green markets erode consumer trust, creating dual impediments to sustainable consumption and supply chain efficiency. Blockchain addresses these challenges by leveraging its unique technical features. This research analyzes a two-stage green supply chain comprising a manufacturer and retailer, developing three models with key parameters: green preference levels, trust coefficients, and blockchain traceability costs. These models, which include a baseline non-blockchain model, blockchain-enabled decentralized decision-making and blockchain-integrated centralized decision-making frameworks, are designed to explore blockchain adoption strategies and coordination mechanisms. This research elucidates several critical insights: (1) The optimal level of green production investment correlates positively with consumer green preferences regardless of blockchain implementation. Blockchain incentivizes the manufacturer to boost green investments, stimulating demand, improving retailer profits and Consumer Surplus. (2) Beyond blockchain operational costs, consumer trust levels act as pivotal determinants in decisions regarding blockchain adoption. The manufacturer tends to be more inclined to adopt blockchain technology only when consumer trust levels and the fixed costs of blockchain implementation are both below specific thresholds. (3) Compared with the decentralized decision-making model, the centralized decision-making model exhibits elevated levels of green production investment, significantly higher overall supply chain profits, and an augmented Consumer Surplus. The design of a two-part tariff contract with fixed remuneration enables supply chain coordination. Within a defined threshold range, fixed remuneration can achieve Pareto improvement in profits for both manufacturer and retailer. (4) The asymmetric Nash bargaining equilibrium enables the efficient allocation of post-coordination surplus gains. This research offers theoretical support for blockchain adoption choices in green supply chains, promoting green, efficient, and sustainable supply chain development.

Increasing customer apprehensions regarding the security and nutritional value of agricultural goods are compelling governments and industries to implement traceable, transparent, and reputable logistics management systems. Blockchain-based agricultural logistics management systems guarantee the permanence of data once it is uploaded but cannot cope with the risk of data being falsified before uploading to the blockchain. In this work, we developed a collaborative game model between government bodies and agricultural enterprises based on the evolutionary game theory and explored the influencing factors of enterprises following the rules to share the real traceability information through numerical simulation using MATLAB. The findings show that government incentives and penalties promote positive behavior, and consumer and media supervision contribute to supply chain transparency, but firms tend to share truthful information only when it benefits them. This study builds upon existing research on the impact of social variables on both members' decision-making behavior. It highlights the positive roles of consumers and the media in the supervision of agricultural product traceability, which can help to raise public awareness of social responsibility and thus promote positive interaction in the market.

Blockchain technology has attracted widespread attention due to its advantages of decentralization, as well as non-tampering, transparency, and traceability of information. Fourth-party logistics systems that do not use blockchain incur transaction costs and service quality losses due to the inability to fully control the delivery process, whereas the use of blockchain eliminates the transaction costs and quality losses, but the use of blockchain needs implementation and marginal use costs. To study the conditions for the use of blockchain technology, consider the fourth-party logistics system does not use and uses blockchain technology, and the equilibrium strategies in the two cases are compared. Numerical experiments show that there exists a certain range of blockchain costs which leads to a Pareto improvement in profits for both fourth-party logistics and third-party logistics and an improvement in the quality of logistics services when using blockchain.

The utilization of blockchain technology is increasingly emerging as a catalyst for significant changes across multiple industries, including the domain of Islamic finance.

The investigation utilizes Partial Least Squares Structural Equation Modeling (PLS-SEM) as a statistical technique to examine the association between several crucial variables, namely Trust, Financial Transfers, Operating Expenses, Safety and Security, and the effective implementation of blockchain technology. The results indicate that these variables have a major impact on the effectiveness of implementing blockchain technology, confirming its ability to boost the efficiency of transactions, decrease expenses, and enhance security while adhering to Shariah law. This work makes a vital contribution to the scholarly discourse around the deployment of technology in the context of Islamic banking. In particular, it emphasizes blockchain technology's part in fostering innovation within the sector and fostering a culture of compliance with the sector's ethical and operational standards.

The Internet of Things (IoT) has become essential for business. The adoption rate of IoT has dropped recently and this could be due to security, privacy, and trust issues. Blockchain (BC) has the potential to mitigate the risk of security, privacy, and trust. However, few studies examined the integration between IoT and BC in the context of developing countries. The purpose of this study is to examine the predictors of IoT adoption by telecommunication companies in the Gulf Cooperation Council (GCC). In addition, the study aims to examine the moderating role of BC as well as the effect of using IoT and BC on the competitive advantage of companies. Based on technology acceptance model, social exchange theory, and resource-based view, the study proposed that security, privacy, trust, communication quality, perceived ease of use (PEOU), and perceived usefulness (PU) affect positively the adoption of IoT. BC is proposed as a moderating variable and expected with IoT to affect the competitive advantage of companies. The population includes all the telecommunication companies in GCC. Data was collected using purposive sampling from IT professionals. The results of data analysis using SmartPLS showed that security, privacy, trust, PU, and PEOU positively affected the adoption of IoT. BC and IoT adoption have a positive effect on competitive advantage. Further, BC moderated only the effect of security and privacy on the adoption of IoT. Services providers must enhance the security, privacy, and trust of IoT services by deploying BC technology. Effective integration of IoT and BC will lead to the achievement of competitive advantages.

This research aims to fill the research gap with empirical evidence that exists about the impact of blockchain and smart inventory systems on supply chain performance in the retail industry in the UAE. The proposed model is uniquely researched as no prior research explores the link between supply chain performances, blockchain, and smart inventory in prestigious academic journals. A quantitative technique with convenient cluster sampling is used. A descriptive, exploratory, causal and analytical design was applied—a sample size of 303 respondents was used for data analysis through regression and hypothesis with ANOVA. The findings revealed a significant positive impact of blockchain and smart inventory systems on SC performance. Limited construct-based research can be focused on more industries and constructs for future studies. There are numerous chances for businesses to leverage blockchain technology to their advantage over the competition, giving them the chance to strengthen their market position. Managers must carefully consider the qualities of their goods, services, and supply chains to ascertain whether they require or would sufficiently benefit from blockchain.
