Dominant countries in global value chains (GVCs) tend to become richer, but their dominance does not correlate with diversification. Competitiveness does not determine a country's diversification within GVCs.
Area of Science:
- Economics
- Network Analysis
- International Trade
Background:
- Global value chains (GVCs) are complex networks of production and trade.
- Understanding competitive dynamics within GVCs is crucial for economic policy.
- Previous research has not fully explored the relationship between country dominance and diversification in GVCs.
Purpose of the Study:
- To investigate the relationship between country dominance and diversification in GVCs.
- To analyze the structure of sectoral GVCs and identify dominant players.
- To determine if economic dominance correlates with a wider range of activities within GVCs.
Main Methods:
- Utilized World Input-Output Database (WIOD) data from 2000-2014.
- Modeled GVCs as weighted directed networks with countries as nodes and value-added flows as edges.
- Employed network analysis metrics including in- and out-weighted degree centralization, centrality, and entropy.
Main Results:
- Found no correlation between diversification (entropy) and dominance (degree) in GVCs.
- Dominant countries, often wealthier nations, exhibited a tendency to increase their dominance.
- Diversification within GVCs was not found to be dependent on a country's competitiveness.
Conclusions:
- Economic dominance and diversification are distinct characteristics within GVCs.
- Wealthier nations consolidate their positions rather than diversifying their GVC participation.
- Competitiveness alone does not drive or explain a country's level of diversification in global value chains.

Entropy
Entropy
When an ideal gas expands isothermally, the disorder in the gas increases. From the molecular perspective, the gas molecules have more volume to move around in.
Consider an infinitesimal step in the expansion, which...

Entropy Change in Reversible Processes
The statement can be further generalized to prove that entropy is a state function. Take a cyclic process between any two points on a p-V diagram.
Entropy and the Second Law of Thermodynamics
The relation between entropy and disorder can be illustrated with the example of the phase change of ice to water. In ice, the molecules are located at specific sites giving a solid state, whereas, in a liquid form, these molecules are much freer to move. The molecular arrangement has therefore become more randomized. Although the change in average...
