This study addresses this gap by employing a Spatial Durbin Model (SDM) using municipal-level panel data from 2000 to 2020 across 250 regions in South Korea. Our research results indicate that, in the long term, the presence of KTX stations does not significantly stimulate employment growth in the host regions. Instead, the employment effects of KTX are primarily indirect, operating through positive spillovers in adjacent areas. This contrast suggests that HSR acts less as a net generator of new employment and more as a tool for the spatial redistribution of labor, a logic driven by the interplay between enhanced labor mobility and the spatial constraints inherent in core urban areas. This pattern highlights the role of HSR as a catalyst for regional integration, enhancing interregional labor mobility and economic interaction. Sectoral analyses further reveal three distinct mechanisms: the construction sector experiences direct local job growth near KTX stations (centripetal siphoning), while health and social welfare (centrifugal relocation) and transportation and warehousing (peripheral derivation) benefit through spatial spillovers. In contrast, manufacturing, finance, and retail sectors show limited sensitivity to passenger-oriented infrastructure. These results suggest that maximizing the employment benefits of HSR requires coordinated regional planning, targeted industrial strategies, and investment in secondary cities to mitigate potential “hub siphoning” effects.</div></div>","PeriodicalId":47453,"journal":{"name":"Research in Transportation Business and Management","volume":"67 ","pages":"Article 101727"},"PeriodicalIF":4.4,"publicationDate":"2026-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148167504","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The main findings show that the hierarchy of preferences has not changed, but the magnitude of the probabilities changed substantially after the pandemic. In particular, the probability of choosing a low-cost carrier for travel to southern Italy decreased in the post-pandemic year compared to 2019, with potential implications for tourism development in peripheral regions. Furthermore, tourists who choose to fly with lowcost carriers have helped mitigate the typical summer peak season. Finally, the relative importance of origin markets changed, especially for Germany.

This study proposes a stochastic green hub network design model for LCCs by integrating seasonal demand variations and carbon emission costs into the network expansion process. Building upon a previously developed deterministic model, this research introduces stochastic definitions for economies of scale parameters and incorporates environmental cost penalties to achieve a greener and more adaptive flight network. The results indicate that carbon emission costs play a significant role in hub location selection, leading to substantial shifts in network structure under varying seasonal and environmental conditions. Furthermore, the findings demonstrate that integrating seasonality and carbon constraints enhances the operational resilience of LCC networks, enabling more efficient and sustainable service continuity amidst market and environmental uncertainties. Compared to the deterministic formulation, the stochastic green model reduces total network cost variability across parameter and seasonal scenarios by approximately 25 % (from −12.3 % to +14.7 % under simultaneous perturbations) while preserving up to 1.5–1.8 % more OD coverage under adverse conditions and maintaining largely stable hub configurations, providing quantitative evidence of improved operational resilience.

To conduct this analysis, the study uses a quantitative approach, where 527 questionnaires were administered in Romania, an emerging market for car sharing. Subsequently, the analysis was conducted using partial least squares structural equation modelling (PLS-SEM) with emphasis on both the direct and indirect impacts that these factors may have on young individuals' willingness to opt for car-sharing solutions. Findings reveal that the model successfully explains 36.2% of the variance in behavioural intentions towards car-sharing. Key findings of the research confirm the significant positive effects of expectations of car-sharing performance and technology embracement on behavioural intentions to use car sharing but indicate a negative impact of transaction costs on the respective intention. At the same time, unexpectedly transaction costs displayed a positive influence over passengers' trust, while the other drivers had positive influences on passengers' trust, as assumed. The results also highlight the significant mediating role of passenger trust across all hypothesised relationships within the model, pointing to the complex nature of factors influencing car-sharing adoption among Generation Z. The contributions of the research are multi-folded. First, from a theoretical perspective, the study reinforces the use of the Theory of Planned Behaviour (TPB) in the particular context of car-sharing for a specific user category, GenZ, while expanding the TPB model by adding trust as a psychological mediator. Further on, in applicative terms, implications are both practical (i.e., suggesting enhanced management and communication strategies for car sharing providers) and policy oriented (i.e., suggesting policy directions for policy makers in terms of sustainability and awareness development).</div></div>","PeriodicalId":47453,"journal":{"name":"Research in Transportation Business and Management","volume":"67 ","pages":"Article 101638"},"PeriodicalIF":4.4,"publicationDate":"2026-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147388002","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

An integrated conceptual framework was developed based on five established principles: diffusion of innovation, resource matching, transaction costs, the theory of planned behaviour and perceived risk theory. The data were collected through a structured survey of 1689 respondents from Egypt, Morocco, Kingdom of Saudi Arabia (KSA) and United Arab Emirates (UAE). The proposed model was tested using structural equation modelling. The study follows a multi-study approach, as it evaluates the model at the regional MENA level and individually for each of the four countries through multi-group analysis to assess differences across countries. The analysis confirmed that relative advantage, local convenience, and energy-saving intention significantly improved sustainable consumption behaviour, while transaction costs had a negative impact. Sustainable consumption behaviour emerged as a strong predictor of intentions to use pickup points and acted as a partial mediator between each of the four antecedents and behavioural intention. Perceived risk has a negative moderating effect in Egypt, Morocco and KSA, but this effect was not significant in the UAE.

Contrary to earlier studies, this study proposes a new sustainable circular agriculture supply chain and logistics network, incorporating a multi-objective mixed-integer linear programming model that considers current important real-world business concerns, like water consumption, agrochemical use, and new Agrivoltaic technologies.

The performance of the algorithms is evaluated by several indicators, and a new hybrid multi-objective decision-making approach is proposed to ease the comparison of the algorithms. Adjustments in influential logistics and transportation parameters and different aspects of the proposed problem are explored through several sensitivity analyses.
