We draw 222 manufacturing firms from the FactSet Shipping database, with 3,348,595 unique observations covering time period between January 2014 and December 2019. By applying multivariate time series clustering algorithm, we identify seven unique clusters for these firms. We further examine the disruptive effects of these tariffs by using intervention analysis of time series in each cluster. The results of intervention analysis demonstrates that disruptive effects differ in each cluster. An additional analysis reveals that firm size, growth potential, and firm profitability are associated with firms’ ability to deal with disruptions.

In today's competitive and complex supply chain networks (SCNs), firms do not operate in isolation but heavily rely on their partners. This interdependence may shape their investment behaviours. However, the mechanism of how the network structure affects the financialization of firms in SCNs is yet unclear. Therefore, this study draws on the resource dependence theory to investigate the role of network structure—encompassing network power and control—in shaping corporate financialization in SCNs. We construct SCNs for the focal firms in a sample of 2307 Chinese listed enterprises from 2009 to 2021 and find significantly negative relationships between corporate financialization and both network power and control. This may be because network power and control diminish enterprises' precautionary saving and speculative motivations through financing and information channels. Moreover, their effect on corporate financialization was found to be more pronounced for non-state-owned enterprises (non-SOEs) and firms with low market share, high customer concentration, and distant supply chain geographic proximity. Furthermore, our results indicate that enterprises exhibiting greater network power and control in SCNs tend to reduce their financial investments, which benefits their innovation and total factor productivity. By exploring the factors that influence corporate financialization through a network lens, this study offers valuable insight into the issues regarding financialization, thus promoting the sustainable development of firms and the development of countries' real economies.</div></div>","PeriodicalId":14287,"journal":{"name":"International Journal of Production Economics","volume":"280 ","pages":"Article 109476"},"PeriodicalIF":9.8,"publicationDate":"2024-11-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142745542","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In contrast to the existing literature, which primarily examines the introduction of blockchain technology from the perspective of cost factors, this paper investigates the platform's blockchain introduction in the context of competition between the new and refurbished products and its impacts on the manufacturer's and the refurbisher's profitability. Motivated by practices, two prevalent selling modes for the new product are considered: reselling mode (R) and agency selling mode (A). Even without considering the cost of blockchain, we find that the platform may have no incentive to introduce blockchain under both modes because it could trigger a severe cannibalization problem or an excessively high price for the refurbished product. The refurbisher (manufacturer) benefits with (without) blockchain under mode R, but this result occurs under mode A only when the blockchain service fee is low. We also discuss the welfare and environmental implications of blockchain.

Related literature has considered a diversity of relationships between Lean and Industry 4.0 but used contradictory models to explain their associations to operational performance. Also, while much attention has been given to the contribution of Lean and Industry 4.0 to operational performance, little is known about their effect on worker outcomes. Therefore, we aim to investigate how these two paradigms interact and their effects on both operational performance and worker outcomes. We propose competing research models – mediation and moderation – to explain plausible relationships between Lean and Industry 4.0 on worker outcomes and operational performance. We test these models through empirical analysis of survey data from 415 manufacturing companies. Our results reveal that Industry 4.0 technologies act as antecedents when they are used to enhance Lean practices for operational performance (Lean as mediator) but serve as moderators in shaping worker outcomes within Lean systems. We also examine the detailed relationships between specific Lean bundles and Industry 4.0 technologies. Our findings highlight the need to strategically balance the adoption of technologies that support Lean for operational performance improvements with technologies that modify worker activities to enhance overall worker outcomes.

Human-robot collaboration (HRC) is an appropriate solution to enhance the productivity of manual systems compared to traditional robots. However, to ensure the success of HRC implementation, it is necessary to investigate the production systems, considering several influencing factors. Workforce diversity can be mentioned as one of the factors since workers may possess different skills and experience levels, as well as varying levels of fatigue. Therefore, creating a realistic and effective optimization model that includes workforce diversity is crucial. This study proposes a mathematical model to optimize a human-robot collaborative assembly line performance to minimize the cycle time. The model integrates several collaborative scenarios (i.e. sequential, simultaneous, supportive and all possible combinations), and the workforce differences are considered in terms of skill level and fatigue, allowing the flexible selection of collaboration scenarios across the assembly line and assigning workers and cobots to stations based on individual characteristics.

This research identifies a significant gap in existing methodologies for the scheduling, routing, and assignment of floating cranes, which are essential for improving efficiency and sustainability in maritime logistics. To bridge this gap, we propose the Reinforcement Learning Variable Neighbourhood Strategy Adaptive Search (RL-VaNSAS) algorithm, a novel integration of reinforcement learning with variable neighbourhood search strategies. This advanced model aims to holistically minimize energy consumption, labor costs, and penalty costs, while simultaneously enhancing service efficiency. Through rigorous simulations, RL-VaNSAS was benchmarked against conventional methods such as Differential Evolution (DE), Genetic Algorithm (GA), and the original Variable Neighbourhood Search Adaptive Strategy (VaNSAS), revealing its superior capability in significantly reducing annual energy costs to $1,211,948, labor costs to $270,948, penalty costs to $19,948, and operational hours to 12,087. Demonstrating notable advancements in operational efficiency and cost reduction, RL-VaNSAS offers a sustainable solution to the dynamic challenges of maritime logistics, characterized by fluctuating vessel arrivals and diverse cargo requirements. The findings illuminate the critical need for innovative optimization techniques in enhancing the sustainability and efficiency of maritime logistics operations.
