Communities in world input-output network: Robustness and rankings

Abstract

We introduce a method for assessing the robustness of community detection and apply it to a world input-output network (WION) to obtain economically plausible results. This method enabled us to rank communities in the WION in terms of their robustness and stability. The algorithmic assignment variability index proposed in this study is shown to have predictive power in terms of forthcoming community rearrangement. We also provide several new approaches for identifying key economic communities. These approaches are based on the application of several centrality measures to a synthetic network in which nodes represent WION communities. Using these methods, we show that in 2000–2014, United States and Japan-centered communities demonstrated decreasing trends, while the importance of the China-centered community predominantly increased. A notable feature of the Germany-centered community rank evolution is that its influence grew only as a result of the inclusion of the Netherlands and Belgium in 2013.

Analysis of the impact of network characteristics on the industry's value-added rate

“…A parallel observation is reported in an international study (del Río-Chanona et al ., 2017), highlighting similar findings. Another international study, conducted by Kireyev et al . (2022), similarly underscores the high correlation between eigenvector and PageRank.…”

“…Additional notable contributions include those by del Río-Chanona et al . (2017) and Kireyev et al . (2022).…”

“…Other studies that correlate centrality with primary objective measures such as value added and profit rates in network research include Harvey and O'Neale (2019), del Río-Chanona et al . (2017) and Kireyev et al . (2022).…”

“…Meanwhile, PageRank and eigenvector centrality has been employed in studies by del Río-Chanona et al . (2017), Kireyev et al . (2022) and Harvey and O'Neale (2019).…”

“…Another PageRank-focused study was conducted by Kireyev et al . (2022), who also examined the international trade market (world input–output table).…”
