This policy brief examines the network of Philippine ports and its partner country products and aims to describe the relative importance of each port over time, as well as the clusters of ports and partner products. The former was done by employing weighted centrality measures, and the latter through an algorithm of community detection within bipartite networks. The study found that ports in Metro Manila dominate in terms of number of transactions over time, with the rankings hardly changing over the study period. It also found that large ports tend to be in a cluster of their own, signifying that these may serve a separate niche market which makes it hard for other ports to substitute, even if they are located close to Metro Manila.
