Fig. 5

Entire Regional Input‒Output Network (in Steady State, Hokkaido, 2005). Visualization based on the input coefficients matrix of the interregional Input‒Output Table 2005. The thickness of edges corresponds to the scale of input coefficients (thick if ω ≥ 0.05; moderate if 0.03 ≤ ω < 0.05; thin if 0.01 ≤ ω < 0.03; or omitted if ω < 0.01). Darker color of nodes indicates higher intensity of self-input. Industries are described in abbreviation in Table 3
