Visualizing Global Value Chains: Smile Curve, Network and Revealed Comparative Advantage
他機関との共同研究成果
To visualize global value chains (GVCs), IDE-JETRO offers some GVC visualization tools at country, sector and bilateral levels based on inter-country input-output (ICIO) models and databases. These tools include smile curves, GVC networks and value-chain based Revealed Comparative Advantage (RCA) figures and source data which have been used in the “Global Value Chain Development Report 2017, 2019, 2021, and 2023”. Examples are shown below.
1. Smile Curve Figure (example)
Smile curve tools display the value-added gains (bubble size), positions (X-axis) and value-added ratio (Y-axis) of various countries and sectors along a specific value chain.
2. GVC Network Figure (example)
Network tools illustrate the interdependency of value-added trade among countries by trading route, their dynamic changes over time and the influencing area of a specific hub country (as supply or demand center) in GVCs for a specific sector.
3 GVC-based RCA Figure (example)
Global value chain-based RCA tools indicate the relative advantage or disadvantage of a certain country in a certain category of value-added exports by trading route (traditional trade, simple GVC and complex GVC trade).
As the initial version of the Global Value Chain (GVC) visualization tools, we provide free-downloadable results for all countries/regions included in the corresponding international input-output datasets. These results cover selected sectors such as Textile, ICT, Auto, and Financial Services, and are available for various years. For a comprehensive explanation of how we generate these figures and additional details about country names, sector names, and the data sources utilized, please consult our Technical Note provided below.
