A New Connectivity Index for Container Ports
نویسندگان
چکیده
We propose a new index, the Container Port Connectivity Index (CPCI), to measure the trade connectivity of ports within the network of container shipping. This index is based on both economics and network topology, and a distinctive feature is that the strength of a port is based on its position within the global structure of the shipping network and not just on local information such as the number of TEUs handled or direct links to other ports. Furthermore, it produces separate scores for inbound and outbound container movement and so supports more detailed analyses. We explore the usefulness of this index by analyzing the global network of scheduled mainline container-shipping services as it existed in September 2011. The interested reader may wish to explore the global network of container shipping in more detail at http://www2.isye.gatech.edu/~jjb/wh/apps/transportation/ container-network.html.
