We study the topological properties of the multinetwork of commodity-specific trade relations among world countries over the 1992-2003 period, comparing them with those of the aggregate-trade network, known in the literature as the international-trade network (ITN). We show that link-weight distributions of commodity-specific networks are extremely heterogeneous and (quasi) log normality of aggregate link-weight distribution is generated as a sheer outcome of aggregation. Commodity-specific… 
Community Structure in the Multi-network of International Trade
TLDR
Plastics and mineral fuels have the highest similarity with aggregate trade communities; both at aggregated and disaggregated levels, physical variables such as geographical distance are more correlated with the observed trade fluxes than regional-trade agreements.
A Network of Networks Perspective on Global Trade
TLDR
This study employs multi-regional input-output data to decompose 186 national economies into 26 industry sectors and utilizes the approach of interdependent networks to analyze the substructure of the resulting international trade network for the years 1990–2011, revealing specific industrial sectors tend to favor distinct directionality patterns and that the cross-clustering coefficient for geographically close country pairs is remarkably high.
The evolution of world trade from 1995 to 2014: A network approach
ABSTRACT This paper employs network analysis to study world trade from 1995 to 2014. We focus on the main connective features of the world trade network (WTN) and their dynamics. Results suggest that

Randomizing world trade. I. A binary network analysis.
TLDR
It is shown that, remarkably, the properties of all binary projections of the ITN can be completely traced back to the degree sequence, which is therefore maximally informative and should instead become one the main focuses of models of trade.
Bridging nestedness and economic complexity in multilayer world trade networks
Understanding the complexity of international trading is critical for a variety of issues ranging from quantifying the competitiveness of individual nations to forecasting the collective evolution of
Hierarchicality of Trade Flow Networks Reveals Complexity of Products
TLDR
It is claimed that the allometric scaling exponent can be used to characterize the degree of hierarchicality of a flow network, i.e., whether the trading products flow on long hierarchical chains.
Identifying the community structure of the food-trade international multi-network
Achieving international food security requires improved understanding of how international trade networks connect countries around the world through the import-export flows of food commodities. The
Distance-varying assortativity and clustering of the international trade network
TLDR
It is shown that trade partnership choices and trade patterns are highly differentiated over different distance ranges, even after controlling for the economic size and income per capita of trading partners, and it is persistent over time.

World-trade web: topological properties, dynamics, and evolution.
TLDR
It is shown that all node-statistic distributions and their correlation structure have remained surprisingly stable in the last 20 years -and are likely to do so in the future -and the distribution of (positive) link weights is slowly moving from a log-normal density towards a power law.
The architecture of globalization: a network approach to international economic integration
We combine data on international trade linkages with network methods to examine the global trading system as an interdependent complex network. We map the topology of the international trade network,

TLDR
This network displays the typical properties of complex networks, namely, scale-free degree distribution, the small-world property, a high clustering coefficient, and, in addition, degree-degree correlation between different vertices.
Fitness-dependent topological properties of the world trade web.
TLDR
It is found that the power-law distributed gross domestic product can be successfully identified with the hidden variable determining the topology of the world trade web: all previously studied properties up to third-order correlation structure are found to be in excellent agreement with the predictions of the model.
