The evolution of the GVTs rooted at South Korea’s electrical equipment industry (KOR_14).

<p>Panels (a), (b), and (c) show the GVTs for 1995, 2003, and 2011 respectively. The edge weight threshold is set to 0.019. Different colors of the nodes indicate different countries. The red edges indicate cross-country relationships while the gray edges indicate domestic relationships. The edge width is proportional to the edge weight, i.e., the share of the value-added contribution. China’s cluster is with light green color.
