This paper investigates the centrality of cruise ports in the Asian cruise shipping market while proposing the hubs and authorities centrality (HACC) metric as a directional synthesis of the hubs centrality and authorities centrality to explore cyclical and directional features of centrality in the cruise shipping network. With the development of the cruise shipping industry, research has been actively conducted with a particular focus on identifying the characteristics of hub ports. This paper employs social network analysis to investigate the HACC which is originally developed for analyzing the cruise port centrality problem. Empirical study implies that Ho Chi Minh City, Hong Kong, Nagasaki, Penang, Phuket, Port Klang, Shanghai, and Singapore (in alphabetical order) reflects particulars of cruise hub ports. One of the exceptional results of this paper is Ho Chi Minh City, Penang, Phuket, and Port Klang have demonstrated high HACC (refers to hub ports) while limited degree and betweenness centrality. In contrast, Busan and Keelung are not classified as hub ports. 相似文献

ABSTRACTBased on an analysis of 253 related papers drawn from the Web of Science database, this study examines holistic sustainability research in liner shipping management literature using a citation network analysis (CNA) approach followed by a qualitative analysis of findings. We identify four major research domains, namely shipping performance, port selection and management, shipping markets, and environment, as well as related sub-domains of shipping performance. We discuss the current research trends and focal issues in these domains with a focus on their implications for policy development. Our results indicate that while the sustainability discourse in the literature has developed and matured significantly over the last decade, generating valuable insights for practitioners and regulators alike, it still struggles with blurry terminology and a lack of holistic frameworks jointly addressing the different aspects of sustainability: Economic considerations of liner shipping are still the main concern, while environmental and social issues are less regarded in the academic discourse. Furthermore, we identify a dearth of studies rooted in managerial or economic theory. In this regard, our study provides insights on the scope of the holistic sustainability discourse in liner shipping management, its contributions to theory and practice, and its implications for the further development of policies addressing sustainability in liner shipping management. We advocate further construct development for sustainability in liner shipping, as well as empirical tests of the antecedents of sustainability practice adoption in the industry for future research. 相似文献

As the dry bulk shipping market seems to have been stuck in a trough period for a long time, investors need to pay more attention to their investment strategies to survive during this period. This study aimed to find a suitable model to assess dry bulk ship investment decisions in the tough and peak periods based on real options theories. Two options, involving an abandonment option and a deferrable option, were used to define investors’ responses to the uncertainty in investment processes such as stopping or selling vessels. The option valuation was solved by using a binomial valuation model, due to data limitations. In accordance with shipping cycle theories, different volatility parameters for the tough and peak periods were calculated using a generalized autoregressive conditional heteroskedasticity (GARCH) model. The application of the real options model to a case study involving secondhand ship trading indicated its viability. According to the results of the case study, the new model has advantages over the traditional net present value (NPV) method in uncertain investment environments. Thus, the results demonstrate that the real options model is a more suitable method for use in the current dry bulk shipping market. 相似文献

近些年,因新浏河沙头部的淤浅,长江口南北港分汊口河段宝山北航道的通航环境转差。为找到有效解决方案,利用地理信息系统(GIS)分析近10年该河段的河势变化,研究航道格局调整方案。结果表明,该水域河槽容积、深泓线平面及等深线变化比较明显,新浏河沙包收缩变小,新浏河沙头部逐渐淤浅并向航道方向移动的趋势仍在发展,现阶段可通过微调航道格局改善通航环境。 相似文献

长江口岸直水道泰兴顺直段近期演变分析 总被引:2,自引:0,他引:2
泰兴顺直段是长江下游主要碍航浅滩之一。历年河道实测水文、地形资料表明,该段多年来河道外形相对稳定,但深泓线以及滩槽变化较大。深泓线年际间发生大幅度摆动,鳗鱼沙心滩具有易变反复,不易消失的演变特点,左、右槽主支地位交替发展。并且该河段演变受特大洪水影响很大,甚至出现滩槽易位现象。 相似文献

长江是我国的“黄金水道”,创造超过40%的国内生产总值和约35%的外贸进出口额,是沿江地区交通物流和经济社会可持续发展的重要命脉.然而,航道拥挤、船舶压港、航道出浅等碍航事件在长江却时有发生,特别是在枯水期,严重影响了我国航运的可持续发展.针对长江的实际情况提出了基于事故特征分析的碍航风险研究思路,在现有历史水上交通安全事故数据的基础上,采取相关性分析的方法对各影响因子进行筛选,并通过贝叶斯网络建立碍航风险的网络评价模型,充分利用其在有限数据的情况下处理不确定性问题的能力,对长江碍航风险进行评价和预测. 相似文献
