 The key takeaway from this research is that the structure of relationships between countries and companies can be analyzed using complex system principles. At the country level, a nested structure was found, whereby each country had a specific set of products they exported. However, when looking at individual companies, a local, in-block nested structure was discovered, whereby each company had a specific subset of products they exported. This finding suggests that companies are more likely to specialise in certain products than countries, which could provide insight into how companies compete against one another.
