Macroscopic features of production network and sequential graph drawing

From Butterfly Wings to Sectoral Clusters: Unveiling the Anatomy and the Dynamic of the Moroccan Production Network

“…Additionally, Trade (G00), Transport (H00), and Utilities (DE0, encompassing the industries of electricity, gas and water distribution, sewage and waste treatment) occupy middle positions due to their widespread connections throughout the network. This bipartite structure mirrors the "butterfly" or "bow-tie" pattern observed in other national production networks (Chakraborty et al, 2018;Fujita et al, 2019;Newman, 2018). This structure indicates a balance between industries serving as primary suppliers of intermediate inputs and those acting as major consumers.…”

“…One common feature is the butterfly structure, observed in Morocco and elsewhere. In this structure, sectors with a strong focus on supplying intermediate inputs, which are associated with high forward linkage, are balanced with sectors that chiefly use these inputs to manufacture final products, demonstrating high backward linkage (Chakraborty et al, 2018;Fujita et al, 2019;Newman, 2018). These two subnetworks are linked through the core of the butterfly, thereby incorporating sectors that produce the basic goods (electricity, gas, and water) or services (trade and transport).…”

Special feature: Econophysics 2017: synergetic fusion of econophysics and other fields of science—Part II

“…Four papers (Inoue 2018 The article "Macroscopic features of a production network and sequential graph drawing", authored by Fujita (2019), proposed a new method that can generate successive layouts of changing large-scale complex networks to visualize series of Japanese production networks with supplier-customer link directions. The analysis successfully shows how the bow-tie structure changes with time to find stable core parts and ephemeral peripheral parts.…”
