Abstract

This study investigates whether the world economy has been trending towards interdependence or economic nationalism. Since 2002, the world GDP has been increasing, but international trade has not increased at the same rate. Furthermore, previous studies had indicated complex global value chain production activities had declined. Our research analyzed the Global Value-Added Network (GVAN) built using World Input-Output Tables and a basic input–output model of Trade in Value-Added (TiVA) calculations. Then, we showed how global economies were interdependent either regionally or sectorally as flow-based communities. Moreover, analyzing structural changes of the communities of GVAN from 2000 to 2014, we found that characteristic changes happened in 2004 and 2011. This result illustrates changes in economic trends after the global economic crisis in 2009. In this chapter, we explain the whole study with illustrative examples.
