This paper reviews the extant literature on LCCs, categorizing existing studies into seven major themes: general impact/competition, pricing strategies, efficiency, service quality dimensions, regulatory/policy considerations, airport-related aspects and others. Through our review of more than 300 related academic references, we develop a concise representation of the state of the art, identify key insights, and highlight areas where research has remained rather sparse. In addition, our study synthesizes critical directions for future research to address emerging challenges and opportunities for LCCs during this important era of air transportation.</div></div>","PeriodicalId":47453,"journal":{"name":"Research in Transportation Business and Management","volume":"63 ","pages":"Article 101458"},"PeriodicalIF":4.4,"publicationDate":"2025-08-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145265710","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}

However, limited research has examined how logistics service quality (LSQ) influences customer behavior in emerging e-commerce markets such as Vietnam. Addressing this gap, this study investigates the relationships between LSQ dimensions, customer trust, satisfaction, and repurchase intention in Vietnam's dynamic e-commerce sector, utilizing the Stimulus-Organism-Response (SOR) framework. Data from 981 online shoppers were analyzed using Partial Least Squares Structural Equation Modeling (PLS-SEM) to examine the relationships among nine LSQ dimensions, customer trust, satisfaction, and repurchase intentions. The results reveal that LSQ dimensions such as availability, information quality, order accuracy, order condition, timeliness, and convenience of return significantly enhance trust and satisfaction. Ordering procedures and personal contact quality primarily improve satisfaction, without directly building trust. Trust and satisfaction mediate the relationship between LSQ and repurchase intention, with trust emerging as a key antecedent to satisfaction. Shopping habits moderate these relationships, and demographic factors like age and income influence repurchase intentions. The study contributes to theory by integrating LSQ, trust, satisfaction, and repurchase intention into a unified model, emphasizing the multidimensional nature of LSQ. Practically, it offers recommendations for e-commerce businesses to prioritize key LSQ dimensions, tailor strategies to customer habits, and address demographic variations. Limitations include the reliance on self-reported data, focus on Vietnam, and the cross-sectional design. Future research could explore longitudinal studies, cross-cultural comparisons, and the inclusion of variables like sustainability. This research highlights the importance of LSQ in fostering customer repurchase intentions and provides actionable insights for enhancing logistics strategies in competitive e-commerce markets.</div></div>","PeriodicalId":47453,"journal":{"name":"Research in Transportation Business and Management","volume":"63 ","pages":"Article 101474"},"PeriodicalIF":4.4,"publicationDate":"2025-08-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144772514","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}

Our investigation highlights the vast role of transportation within the SDGs’ scope, which was earlier limited to a few indicators; we stress transportation’s transformative potential, including its role in enhancing urban accessibility, reducing greenhouse gas emissions, promoting equity and inclusion, and fostering economic opportunities. Key findings underscore gaps in the current SDG framework, such as limited recognition of active mobility, inequities in access, and underrepresentation of transportation’s environmental and social impacts. In addition, thresholds for the different indicators interacting with the transport sector must be defined for a universal, transparent evaluation process. Moreover, there is a need to consider the interlinkage between several indicators within different goals that are closely linked, and their relationship should be considered when evaluated, and they should be evaluated simultaneously and not separately. The paper proposes refining indicators to capture the nuanced relationships between transportation and sustainable development, emphasizing context-sensitive approaches to address regional disparities and informal transit systems.

Ports naturally prefer cooperation as it can generate higher profit, but this preference must be contextualized by service relationships. For complementary ports, cooperation can also generate higher social welfare. For substitutable ports, competition is better and should be promoted, while cooperation can lead to monopoly and social welfare losses. Such losses increase with the level of overcapacity compared with competition. The results underscore a key policy implication: rather than universally promoting cooperation, port strategies should be tailored to service complementarity/substitutability. Specifically, encouraging competition among substitutable ports to safeguard social welfare.

Import/export-focused ports were more affected than transshipment hubs, with gateway ports experiencing more severe bottlenecks. Short-term events such as labor strikes also substantially impacted port congestion. Next, using econometric analyses, estimated impulse response functions indicate a decrease in the number of ship calls following stricter mobility restrictions, with average waiting time at anchorage promptly increasing, while average service time at berth was comparatively less affected.

The results demonstrate that features of e-booking, ease of use, and service information significantly enhance the implementation intention to try DRBus, while e-booking, ease of use, and service reliability play a pivotal role in reducing the perceived walking distance to bus stops. The findings further reveal that in-vehicle travel time (IVT) and the number of bus interchanges (NBI) are the key moderators in the relationship between walking distance and their implementation intention to try DRBus. Specifically, shorter walking distances were found to increase the likelihood of adoption; however, this effect diminished as IVT and NBI increased, emphasising the critical role of travel efficiency in influencing commuter behaviour.
