Achieving sustainability has become a global priority, with environmental sustainability gaining significant attention from policymakers due to its critical importance. While numerous studies have empirically examined the relationship between CO2 emissions and green initiatives, they often overlook sectoral differences. Since different sectors contribute unequally to carbon emissions, the environmental effectiveness of green solutions may vary across sectors. This study addresses this research gap by focusing on the transport sector, a major contributor to global CO2 emissions. This study investigates the role of green technology, green energy, green finance, digital economy, economic growth, and urbanization on transport sector CO2 emissions in G-20 economies from 2002 to 2022. Using panel quantile regression, the results reveal that green energy and economic growth reduce transport emissions in lower quantiles; while green energy, green finance, and urbanization enhance environmental quality in upper quantiles. However, green technology is associated with higher transport emissions across all quantiles. Moreover, we employ a simple regression tree model, a machine learning approach, to identify which countries are winners and losers in terms of predicted transport emissions. Our results predict a 13.72 % increase in transport emissions across G-20 nations, with Japan, Australia, Saudi Arabia, the United States, Argentina, Russia, South Africa, South Korea, France, Brazil, India, and Italy among the most affected. These findings recommends shifting to non-motorized vehicles and public transportation systems that enhance transport efficiency and mitigate environmental degradation through green transportation.

This study investigates the efficiency and returns to scale of Korean logistics firms using stochastic frontier analysis of panel data from 2006 to 2019. Drawing on a firm-level dataset from a substantial number of logistics companies, this study assesses the impact of innovation activities, government certification, and stock market participation on firm-level efficiency. The results indicate an average efficiency score of 0.75, with improvements over time primarily driven by investments in research and development and the attainment of government excellence certifications. The analysis reveals that firms engaging in innovative activities exhibit significantly higher efficiency levels, whereas stock market listings have minimal or negative impacts. Furthermore, most logistics companies operate under increasing returns to scale, suggesting that expansion can enhance efficiency and performance. These findings offer managerial insights for logistics firms by emphasizing the value of innovation, certification, and strategic scaling. The study provides policy recommendations aimed at encouraging innovation and certification initiatives to improve the overall efficiency of the logistics industry.

Robo-taxis are fast becoming the new mobility option for city dwellers. Based on the data of 666 valid questionnaires in China, this study conducted a comprehensive analysis across economics, sociology and psychology by using structural equation model (SEM), and explored the key factors influencing the adoption of Robo-taxi by potential users, with special attention to demographic differences. The results show that performance expectation and hedonic motivation significantly enhance the price value of Robo-taxi and enhance the willingness to use it. However, risk perception obviously inhibits the public's willingness to use. In addition, gender, age and education level have important effects on behavioral intention: men attach more importance to economic values, women attach more importance to social factors; With the increase of age, the willingness to use decreased; Higher education is associated with greater willingness to use. Through interdisciplinary analysis, this study reveals how multiple factors work together to make Robo-taxi adoption decisions, providing strategic guidance for autonomous vehicle manufacturers, taxi service providers, and public transportation strategic planners to accelerate public acceptance and adoption of Robo-taxis.

Government outsourcing of highway services (GOHS) has become a popular choice for the public sector who struggles to meet rising demands for highway services but with dwindling resources. However, owing to the incompatibility of objectives, preferences and values among stakeholders of GOHS, interest conflicts are inherent during the process of highway service delivery. To resolve the interest conflicts and promote the development of GOHS policy, this paper employs the graph model for conflict resolution (GMCR) method to simulate the dynamic evolution of interest conflicts among stakeholders. Particularly, text mining technology is used to extract the options of decision makers (DMs) and a segmented option weighting method is proposed to determine the preference rankings of DMs, which contributes to the improvement of GMCR method. After constructing the conflict model with the improved GMCR method, conflict analysis is conducted to find the resolutions of GOHS conflicts. Research results show that governments are suggested to supervise the third-party vendors and take incentive measures to motive contractors to deliver high-quality highway services. Under the supervision, third-party vendors are more inclined to fulfill contracts and comply with the terms of outsourcing contracts. Citizens who are highway service users should also involve in the service delivery process actively and promote the development of GOHS by evaluating and supervising. Additionally, the sensitivity analysis results indicate that the equilibrium state of GOHS conflict is highly sensitive to the DMs' relative preferences over states.

政府将公路服务外包（GOHS）已成为公共部门的一种普遍选择，因为公共部门正努力满足日益增长的公路服务需求，但资源却在不断减少。然而，由于政府公路服务外包的利益相关者之间的目标、偏好和价值观不一致，在提供公路服务的过程中存在着固有的利益冲突。为解决利益冲突，促进全球公路服务政策的制定，本文采用冲突解决图模型（GMCR）方法，模拟利益相关者之间利益冲突的动态演化过程。其中，利用文本挖掘技术提取了决策者（DMs）的选项，并提出了分段选项加权法来确定 DMs 的偏好排序，有助于 GMCR 方法的改进。利用改进后的 GMCR 方法构建冲突模型后，进行冲突分析以找到解决全球统一制度冲突的办法。研究结果表明，建议政府对第三方供应商进行监督，并采取激励措施促使承包商提供高质量的公路服务。在监督下，第三方供应商更愿意履行合同，遵守外包合同条款。作为高速公路服务使用者的公民也应积极参与服务提供过程，通过评价和监督来促进全球公路服务系统的发展。此外，敏感性分析结果表明，政府公路服务冲突的均衡状态对管理部门对各州的相对偏好非常敏感。

Using the Habit Discontinuity Theory (HDT), we explored the habits, perceptions, difficulties and potential disruptions related to ridesharing and ridehailing services in a developing country. The initial data were gathered from 22 individuals in October–December 2022. We used a diverse and multifaceted strategy, including face-to-face semi-structured interviews and participant observations,

which provided complementary insights by capturing real-world practices and interactions beyond verbal accounts. The participants had favourable opinions of the aforementioned services, praising their usefulness, sustainability, adaptability, accessibility, price and speed. Environmental, safety and security concerns influenced their decisions to use or not use these services. In ridehailing services, the participants emphasised the importance of trustworthy background checks on drivers for increased safety. In ridesharing services, the issues of regulatory shortcomings and a lack of government backing were raised, including a lack of clear legislation and licensing frameworks, which breeds mistrust. Government backing and better regulation were considered essential for the sustainable development of this sub-sector of the economy. The participants also emphasised the need for accountability systems and driver training programmes to improve service quality. The study makes valuable contributions, such as offering insightful information to regulators, legislators and ridehailing firms and suggesting that ridehailing businesses prioritise safety measures, such as thorough driver screening procedures and practical approaches to handling rude drivers. Policymakers and regulators are urged to develop precise and practical rules that promote expanding ridesharing services while ensuring consumer safety and protection.

In recent years, the air transport system has faced a number of major setbacks and demands, making the re-evaluation of traditional design and operational paradigms essential. This has also highlighted the need to explore new aircraft configurations offering improved capacity, efficiency, reduced environmental impacts, and better adaptability to evolving market demands. Consequently, this paper focuses on box-wing aircraft, an innovative aircraft configuration that might be a future improvement of current commercial airplanes' tube-and-wing design. While the innovative box-wing configuration has been studied from various perspectives, no research has examined it from a financial standpoint. This paper aims to explore this issue in depth. By leveraging data and financial models developed over a three-year interventionist experience with the Horizon 2020 PARSIFAL project, this article evaluates whether a box-wing aircraft could be a financially viable alternative to existing aircraft configurations. The results suggest that the introduction of a box-wing aircraft as a future mode of air transportation could provide the aviation sector and society with substantial financial benefits.

This paper investigates and compares the economic and environmental benefits of a traditional business model as opposed to a fleet leasing model for electric buses (e-buses). A combination of the emission model and financial model, along with secondary data, was adopted to simulate the environmental and economic impacts of three bus technologies (i.e. diesel buses, compressed natural gas buses, and electric buses). The environmental aspects were evaluated by setting the energy flow of CO₂ emission simulation, considering both direct and indirect emissions. The economic impacts of e-bus versus baseline diesel and CNG alternatives were estimated using the metric total cost of ownership (TCO) per km. We determined that although the mandatory e-bus program might represent a viable option when compared to the combustion alternatives from an environmental standpoint, e-buses are less appealing to bus companies due to their significantly lower cost-competitiveness under a traditional (current) business model. In contrast, a fleet leasing model brings large financial benefits to bus companies, increasing more probability of acceptability and intention of compliance from bus operators. Specifically, our analysis estimates that implementing the e-bus mandatory program with a new leasing model will result in a maximum of 47 %, 90, and 97 % emission removal in 2030, 2040, and 2050 respectively. In the same period, the TCO per km reduces a maximum of 41.8 %, 31.0 %, and 17.4 %, respectively, compared to the traditional business model. The findings can be valuable for cities, practitioners, and bus companies, aiding in a better understanding of the challenges and benefits of the bus leasing model in order to better plan for e-bus uptake in Vietnam.

Serious debt problems have greatly hindered the healthy development of China's toll road industry. The key aspect concerns increasing costs, especially maintenance costs. To address this issue, this paper analyzes the effectiveness of China's toll road maintenance system reform policy by using a sample of state-owned toll road operators (STROs). Based on the time-reversed difference-in-differences (DID) model of transition time, the results show that the implementation of the policy has not achieved the expected cost reduction or efficiency improvement. A further analysis reveals that the main reasons for this policy failure are the incompleteness of the management system reform and insufficient marketization. The findings of this paper provide theoretical and empirical references for implementing further reforms in the toll road industry.

New mobility concepts such as Mobility as a Service (MaaS) are emerging as potential solutions to move people more sustainably in an increasingly urbanized world. Planning for this multi-modal mobility requires a whole system approach (STEEP - social, technical, economic, environmental, and political) to evaluate alternative future scenarios and address varied stakeholder concerns. A strategic planning tool was selected that can model alternative scenarios for how urban mobility systems may evolve over time. A sustainable mobility scorecard was defined, comprised of individual metrics generated from the tool's output. The Analytical Hierarchy Process (AHP) was selected and applied to generate stakeholder weightings from an online survey of U.S. transportation planning professionals. Those weightings were applied to the scorecard to demonstrate their influence on alternative planning outcomes. Results include the scorecard metrics assessed with the greatest relative importance to sustainability; increases in no car ownership, increases in the transit/walk/bike mode share especially in lower income populations, maintaining the average peak traffic speed (actual/posted), and reducing cars per capita. The resulting weighted scorecard, part of a strategic assessment methodology for mobility sustainability (SAMMS), is then used to evaluate four future planning scenarios with contrasting trends (socio-demographics, travel behavior, employment, land use, transport supply) for the greatest overall sustainable mobility outcome.

Results include the scorecard metrics assessed with the greatest relative importance to sustainability; increases in no car ownership, increases in the transit/walk/bike mode share especially in lower income populations, maintaining the average peak traffic speed (actual/posted), and reducing cars per capita. The resulting weighted scorecard, part of a strategic assessment methodology for mobility sustainability (SAMMS), is then used to evaluate four future planning scenarios with contrasting trends (socio-demographics, travel behavior, employment, land use, transport supply) for the greatest overall sustainable mobility outcome.</div></div>","PeriodicalId":47453,"journal":{"name":"Research in Transportation Business and Management","volume":"60 ","pages":"Article 101336"},"PeriodicalIF":4.1,"publicationDate":"2025-03-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143562537","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}

This study examines Ningbo Zhoushan Port as a case to explore how emerging ports enhance global competitiveness through the synergistic effects of multidimensional factors such as innovation input (RD), organisational resilience (RES), and corporate social responsibility (CSR). The research, based on grounded theory using qualitative and quantitative analyses, systematically reveals the internal mechanisms of port development. The findings indicate that innovation input significantly enhances port operational efficiency and economic performance, with organisational resilience as a mediating variable to strengthen this effect further. Moreover, CSR demonstrates a dual effect in moderating the relationship between innovation input and economic performance: it amplifies the positive impact of innovation under conditions of efficient resource allocation, whereas it may diminish innovation efficiency in scenarios of resource dispersion. The study further identifies that national policy integration and the coordinated development of port-adjacent industries significantly enhance the port's adaptability to market fluctuations and long-term competitiveness. By identifying the multiple driving factors and their interactive mechanisms in port development, this study enriches the theoretical framework of port management and economic growth while offering systematic strategic guidance for other ports worldwide. The paper further discusses the critical role of integrated strategies involving innovation input, organisational resilience, and CSR in achieving long-term sustainable development for ports while highlighting the study's limitations and future research directions.
