Fig. 4

Detailed network in agriculture and food processing (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. Agriculture is classified as rice (ric), wheat and barley (wht), other crops (ocr), feeding crops (fed), dairy farming (dai), livestock (liv), and fisheries (fis). Food processing is classified as follows: slaughter (slt), meat products (mtp), dairy products (dap), processed marine products (pmp), rice milling (rml), flour milling (fml), noodles bread confectionary (nbc), other processed products (opp), prepared food products (pfp), and tobacco alcohol tea (tab)
