“…Network diameter refers to the maximum value of the shortest path between any two ports in the cruise shipping network. The larger the network diameter is, the more ports the itinerary has (Ito, Hanaoka, & Sugishita, 2022). The calculation formula is: …”

The frigid geographical environment in the Arctic has shaped the exploration attribute of the polar cruise shipping network. In this study, the typical characteristics and special structure of the Arctic adventure cruise shipping network are investigated by using the network analysis method based on the data of 172 adventure cruise itineraries in the Arctic. It is found that the Arctic adventure cruise itineraries are dominated by 8–17 days of medium itineraries, and the ratio of one-way itineraries to round-trip itineraries is about 1:1. There are differences in the centrality of different ports, forming two core ports Reykjavík and Longyearbyen and a sub-core port Kangerlussuaq. The overall contact strength of the Arctic adventure cruise shipping network is low. Under the joint influence of such factors as centrality and contact strength, the Arctic constitutes the dual-core clusters of Iceland and Svalbard Islands and a sub-core cluster of Greenland.

“…A maritime transport network can be described by tracking the activity of ships since they navigate between ports. The network explains the location and quantity of nodes (ports) that form the network and their edges or links (shipping routes) because of ship activities [32]. An investigation of network connectivity addresses associations amid nodes in a network that are connected by links between them.…”

“…Kanrak et al [35] further analysed the change in the cruise shipping network by comparing the networks before and after the pandemic. Ito et al [32] investigated the structural changes in the cruise shipping network via ship size in Northeast Asia adopting network science approaches along with AIS data. Rodriguez et al [36] adopted 2018 itineraries covering 902 ports to understand structural changes in Northern Europe and the Caribbean cruise networks.…”

“…The cruise ship size can potentially be a limiting factor in accessing the port, and thus, the cruise traffic is concentrated on the specific market along with the network [40]. In response, determining the ship size to be anchored is the starting point of cruise port development [32]. This is crucial in placing ports in a strategic position of home ports in the region and sustaining the competitive position of cruise destinations [37,41].…”

Empirical Analysis of the Cruise Shipping Network in Asia

et al. 2023

The cruise shipping market has been growing dynamically in the past two decades. This study presented an empirical analysis of the Asian cruise shipping network (ACSN) in which the nodes are cruise ports and links are cruise routes connecting the ports, using complex network analysis. An analysis of 245 voyages operated by 16 cruise lines between 215 ports in 26 countries found that ports in the ACSN are connected by 704 links. The ACSN is a small-world network with a small average path length and a high clustering coefficient, and its degree distribution follows an exponential function. A small number of ports have high connectivity, and most ports have low connections. Most high-degree ports connect to low-degree ports. The important roles and properties of ports vary depending on centrality measures.

“…Research on the structural characteristics of innovation networks mainly focuses on the overall characteristics of the network, network positions, and network relationships. In the research on the overall characteristics of innovation networks, indicators such as network density, average clustering coefficient, network centralization, and modularity have been used in studies [14]. In research on the position of innovation networks, most scholars have used indicators such as closeness centrality, betweenness centrality, and constraint to explore the position of nodes in innovation networks [15].…”

To clearly describe the structural characteristics of China's rare earth innovation network (REIN), this study used data on China's rare earth patents since 2001 in the Incopat global patent database to analyze the structural characteristics of China's REIN from 2001 to 2020 at the provincial and municipal levels using social network analysis. The study finds the following: (1) The overall characteristics of the network show that the connectivity and diversification of China's REIN is increasing. (2) The network spatial pattern analysis shows that the REIN exhibits a radial spatial pattern centered on Beijing at both the provincial and municipal levels. (3) Research on network nodes shows that the network is dense in eastern regions and sparse in western regions, showing distinct characteristics of coastal and resource agglomeration. Not all regions with high levels of economic development play leading roles in the REIN. Small and medium-sized cities with abundant rare earth resources also play important
