Shore side electricity (SSE) is a promising solution for mitigating these emissions. Based on Automatic Identification System (AIS) data and national grid emission factors, this study developed a bottom-up model to evaluate SSE's emission reduction potential. We compiled an emission inventory of container ships at 37 coastal ports in mainland China in 2022 and evaluated the effectiveness of SSE. Results show that the emissions of air pollutants (SO<sub>2</sub>, NO<sub>X</sub>, PM<sub>2.5</sub>, CO, and NMVOC) from these ships totaled 5.58 × 10<sup>4</sup> tons, while greenhouse gases (CO<sub>2</sub>, CH<sub>4</sub>, and N<sub>2</sub>O) totaled 2.90 × 10<sup>6</sup> tons. SSE implementation results in significant emission reductions, decreasing overall port emissions by approximately 58 % and berth emissions by nearly 90 %. However, due to substantial differences in port characteristics and regional grid energy structures, the emission reduction potential exhibits considerable heterogeneity across ports. Based on our analysis of emission reduction data across various ports, we propose three targeted strategies: First, at the regional level, in areas with cleaner grid structures and high port activity, SSE facilities should be prioritized. In contrast, in regions that rely on fossil fuels, a combination of clean-energy vessels and route optimization measures should be promoted. Second, at the policy level, it is recommended to stimulate enterprise investment by implementing tiered subsidies, preferential electricity tariffs, and enhanced regulatory oversight. Third, at the implementation level, a collaborative mechanism between ports and shipping companies should be established to jointly optimize the planning and operation of SSE facilities.</div></div>","PeriodicalId":48378,"journal":{"name":"Transport Policy","volume":"167 ","pages":"Pages 130-144"},"PeriodicalIF":6.3,"publicationDate":"2025-03-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143746363","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}

To address the issue of information asymmetry between ports and investors, this paper proposes green port construction with the shore power berth installation rate as a core indicator as a signaling mechanism, constructing a dynamic Bayesian game model to analyze the strategic interactions and equilibrium conditions between ports and investors. The research demonstrates that when the shore power berth installation rate falls within a reasonable range (i.e., the cost of green construction for high-utilization ports is lower than their digitalization returns, while the cost exceeds returns for low-utilization ports), a separating equilibrium can be achieved—efficient ports signal their high quality through green construction to attract investment, while inefficient ports abstain from such initiatives. Numerical simulations, based on data from Hebei Port Group, validate the effectiveness of this mechanism and highlight that excessively high shore power installation standards can lead to a pooling equilibrium, resulting in investor refusal to finance. The numerical simulation also shows the speed at which the game tends toward equilibrium under different conditions. The stronger the profitability of the port after receiving investment, and the greater the probability that investors adopt a strategy to recognize green signals at the initial stage of the game, the faster the game tends to move towards a separating equilibrium.</div></div>","PeriodicalId":48378,"journal":{"name":"Transport Policy","volume":"167 ","pages":"Pages 178-190"},"PeriodicalIF":6.3,"publicationDate":"2025-03-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143760771","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}

Using resource dependence theory and transaction cost theory, we examine the positive role of infrastructure development represented by high-speed railroads (HSR) in alleviating SCD. Our findings reveal that the opening of an HSR can alleviate SCD, but this effect is primarily observed in alleviating downstream large-customer dependence, with no significant impact on alleviating upstream large-supplier dependence. This effect is more pronounced in environments characterized by high levels of economic uncertainty and low levels of digital infrastructure. The opening of an HSR alleviates SCD mainly through two paths: enhancing the competitive market environment and reducing transaction costs. Furthermore, alleviating SCD contributes to enhanced firm resilience. Our research advances the understanding of the relationship between transportation infrastructure and supply chain management, offering insights for academics and practitioners on strategies to alleviate SCD.</div></div>","PeriodicalId":48378,"journal":{"name":"Transport Policy","volume":"167 ","pages":"Pages 116-129"},"PeriodicalIF":6.3,"publicationDate":"2025-03-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143746358","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}

Amid rapid urbanization and expansion of HSR networks, HSR station areas tend to transition from singular transport nodes into multifunctional urban spaces. Although previous studies have assessed the vitality and development potential of station areas, they tend to overlook the diversity in functional characteristics and the varied factors shaping these areas. This study investigates the evolution and differentiation of 197 HSR station areas in the Yangtze River Delta (YRD), China in 2022, focusing on identifying dominant functional types and their determinants of functional differentiation. Offering a novel approach, this study develops a quantitative framework to classify the dominant functional types within HSR station areas, bridging a gap in the literature that has primarily relied on qualitative classifications. The Random Forest algorithm combined with SHAP (SHapley Additive exPlanations) analysis is employed to reveal the mechanisms that influence each functional type, providing a nuanced understanding of their dynamic characteristics. Results reveal the spatial scope of HSR station areas across various hierarchies and identify four dominant functional types: transportation function-dominant, business function-dominant, residential function-dominant, and comprehensive service function-dominant station areas. Each type exhibits distinct economic and geographic characteristics, reflecting specific urban development needs and growth patterns shaped by different factors. Based on these findings, this study proposes policy recommendations aimed at optimizing station area functions, thereby supporting the high-quality development of urban spaces induced by HSR development.</div></div>","PeriodicalId":48378,"journal":{"name":"Transport Policy","volume":"167 ","pages":"Pages 264-275"},"PeriodicalIF":6.3,"publicationDate":"2025-03-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143776361","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}
