A systematic literature review on port competitiveness
No full textThe continuous investment and expansion of ports has introduced new requirements for the sustainable development of seaports. Port competitiveness is an increasingly relevant subject due to the value that ports create for enterprises in the maritime supply chain. As the functions and requirements of ports evolve, this article aims to present an up-to-date review of the research trends and future directions of port competitiveness. A systematic literature review was performed to comprehensively gather and review 81 journal papers on port competitiveness published in the past two decades. The result shows a hierarchy of the top ten port competitiveness drivers based on their research frequency in the literature, categorised into four aspects. The frequency ranking of port competitiveness strategy is further summarised based on the reviewed papers. This paper also provides a critical analysis of port competitiveness mechanism in order to identify research trends, gaps, and future research directions.</p
Building sustaining port competitiveness constructs: a case study of ports in China
No full textBackground: Ports play a pivotal role in global logistics and the supply chain by handling a significant volume of cargo transported worldwide. The continual investment and expansion of ports necessitate new requirements for their sustainable management. With the rapid spread of the COVID-19 pandemic worldwide, there has been a profound impact on global economic and trade development, leading to surge shipping prices have surged, and regional policies have also affected port production activities. Global port congestion, labour shortages at ports, and other challenges underscore the critical role of ports in the maritime supply chain. Similarly, trade conflicts between China and the United States have disrupted the normal operations of the port industry, underscoring the significance of ports in the maritime network. Port competitiveness is an increasingly pertinent subject due to the value that ports bring to enterprises in the maritime supply chain, and more broadly, to the economic, social, and environmental development of the regions in which they are located. Purpose: With the constantly changing port market environment, shipping backgrounds, and local policies, the factors affecting port competitiveness need to be reconsidered and updated. Some factors may have become less influential on port competition than before, while others, previously overlooked or lacking in-depth research, may potentially improve port competitiveness. To address this gap, this research aims to explore issues important for port competitiveness in Chinese ports and how can port competitiveness be improved through sustainable competitiveness strategies. Insights are drawn from cutting-edge topics of research in port management, including port supply chain integration, port collaboration and port sustainability, for the investigation of the port competitiveness and competition.Approach: First, a systematic literature review was conducted, comprehensively gathering and reviewing 81 journal papers on port competitiveness published in the past two decades. Research trends, gaps, and opportunities in the field were discussed based on a critical analysis of the port competitiveness mechanism. Then, a grounded theory approach was utilized to systematically construct the theory of sustaining port competitiveness grounded in the data. This research utilized a theoretical sampling approach to investigate how port operators and stakeholders understand sustaining port competitiveness. The data were primarily collected through 35 semi-structured interviews with representatives of experts, Chinese port companies, and stakeholders, including shipping lines, cargo forwarders, and port service providers. After data collection, the strategy of coding and comparative analysis was adopted to categorize issues and construct the prototype of the theory. By summarizing findings and comparing them with the literature, several dimensional frameworks and the model of sustaining port competitiveness were constructed.Findings: The study's findings suggest that China’s port competition and competitiveness are influenced by several cutting-edge trends in the shipping and supply chain industry, such as port supply chain integration, port cooperation, and port sustainability. The results of the data analysis show that the sustainable competitiveness of the port can be classified into four dimensions: resource-based advantages, platform advantages, network advantages, and sustainable advantages. A theoretical framework was accordingly developed to deeply understand the relationships of these four dimensions to a port’s sustainable competitiveness. Resource-based advantages represent the traditional strengths that ports possess, typically not easily altered. Achieving sustainable competitiveness requires two major strategic advantages: platform and network advantages, which can be enhanced by establishing appropriate strategies. To maintain a high level of competitiveness in the long term, ports need to consider the potential elements of sustainable advantages.Moreover, this research discussed seven sustainable port competitiveness strategies, which are: 1) Attracting investment and construction; 2) Establishing port alliance; 3) Attracting shipping companies; 4) Attracting cargo from the hinterland; 5) Optimizing logistics service; 6) Developing innovative technology; 7) Capitalizing on the policy and national strategies. Contributions: This research significantly advances the theoretical landscape of port and shipping studies. It enhances understanding by conducting a comprehensive literature review, introducing the concept of sustainable port competitiveness, and proposing conceptual frameworks. The study offers fresh perspectives on port competitiveness from port resources, port supply chain, cooperation, and sustainability angles, paving the way for diversified approaches in future research. Additionally, it provides practical implications for both port operators and policy makers, guiding operators to enhance their competitive edge, attract investors, and optimize strategies for long-term competitiveness. Policy makers can leverage insights to design policies that encourage sustainable development, eco-friendly practices, trade facilitation, investment, and skill development, fostering a collaborative approach that contributes to the industry's resilience and positive socio-economic and environmental impact
Study on the propagation of sustainable development concept among Gulf ports based on complex network
No full textThe development of the Gulf ports group has brought challenges to the marine environment and global climate change. Deconstructing the propagation mechanism of the sustainable development concept among the Gulf ports group will help to provide a new perspective for the ports governance in the Gulf region. This paper constructed the ports relationship network of Gulf region with the method of complex network, established the propagation model of sustainable ports concept, and simulated the model. The results suggest that: the relationship structure of Gulf ports group affects the spread of sustainable development concept, and the political conflicts, complex interest structure and randomization of ports network in the Gulf region will hinder the spread of sustainable development concept to some extent; the enhancement of ports’ sustainable development competitiveness in Gulf region can effectively promote the spread of sustainable development concept, and the increasing pressure of international regulations on sustainable development and regional consensus will make ports more receptive to the concept of sustainable development
Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
