This study examines the impact of geopolitical tensions on port-level carbon emissions using a monthly panel dataset covering 269 container ports across 40 countries and regions from 2016 to 2023. Employing a system generalized method of moments (SYS-GMM) estimator, we find that heightened geopolitical risks significantly increase carbon emissions at ports. A key mechanism underlying this relationship is that geopolitical tensions disrupt the vessel arrival schedules, which reduces port efficiency, and consequently increases emissions from ships at berth. Further heterogeneity analyses reveal that the environmental impact of GPR is more pronounced at ports serving larger container vessels, as these ports are typically involved in long-haul routes that are more exposed to geopolitical disruptions. In contrast, the impact is less significant at ports with fewer calling carriers, likely because dominant shipping lines tend to internalize the costs of inefficient berthing by smoothing vessel arrival times. This study provides novel empirical evidence on the environmental consequences of geopolitical shocks in the maritime sector, offering actionable policy insights for risk-sensitive and sustainable port governance.</div></div>","PeriodicalId":48378,"journal":{"name":"Transport Policy","volume":"173 ","pages":"Article 103809"},"PeriodicalIF":6.3,"publicationDate":"2025-09-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145049751","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 findings indicate that individuals exhibit risk preferences in response to waiting time uncertainty. When waiting times are shorter than expected, they show risk aversion with diminishing sensitivity to further reductions. Conversely, longer-than-expected waits lead to risk-seeking behavior, heightened sensitivity, and biases in probability perception. These risk preferences significantly influence individuals' parking choices, particularly in prolonged, uncertain waiting scenarios. Additionally, travel context factors (e.g., purpose, activity duration, and idle time) and parking attributes (e.g., cost, revenue, and social influence) significantly influence AV owners' parking decisions, along with socio-demographic characteristics (e.g., age, education, and car ownership).

This study represents one of the initial attempts to quantify the dynamic impacts of HSR on the upgrading of urban industrial structures. It distinguishes the sources of these impacts by considering the lagging effects for individual cities and the staggered expansion of the HSR network. In addition, the industrial structure upgrading is comprehensively evaluated from the servitization of the industrial structure and the improvement of industrial labor productivity. In which, the industrial structure servitization represents the upgrading of industrial structure towards tertiary industry. Using data from 278 Chinese cities over a span of 19 years, we developed and employed an improved synthetic control method (SCM) and staggered SCM for our empirical investigations. The results indicate that HSR generally facilitates the upgrading of a city's industrial structure. However, the effects of HSR on industrial structure servitization tend to fade quickly, while the impacts on improving industrial labor productivity are more persistent. Further regional heterogeneity analyses suggest the effects of HSR on industrial servitization is more enduring in core cities, while the labor productivity-improving impacts of HSR remain consistent across different cities.</div></div>","PeriodicalId":48378,"journal":{"name":"Transport Policy","volume":"173 ","pages":"Article 103806"},"PeriodicalIF":6.3,"publicationDate":"2025-09-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145020154","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 develops and tests a comprehensive model of UAM acceptance by integrating the constructs of perceived safety (PS), perceived usefulness (PU), price sensitivity (PSen), environmental awareness (EA), trust (TR), and behavioral intention (BI). Drawing upon technology acceptance models, risk perception theory, and environmental psychology, we analyze survey responses (N = 427) through structural equation modeling (SEM) to elucidate the drivers, barriers, and moderating factors influencing the potential uptake of UAM services. Results highlight that perceived safety positively influences trust, which mediates the effect of safety on behavioral intention. Perceived usefulness emerges as the strongest direct predictor of intention, while high price sensitivity curtails adoption. Environmental awareness exerts a modest positive impact on acceptance and moderates the adverse effect of high price sensitivity. These findings underscore the importance of transparent safety standards, strategic fare designs, and the communication of environmental benefits for promoting UAM adoption.
