Information and communication industry input-output tables are published every year. If we want to compare intertemporaly these tables, first, we must transform qualitative information and communication industry input-output tables by performing a coarse graining.In this study, we investigate the impact of these coarse-graining on the network scale. As the network scale, we use network centrality measures and centaralization.
