Figure 2

Sample abstraction for possible linkages in a country’s specialization pattern. This figure represents a stylized example of a possible result of our investigations. We consider three sets of activities: export of services, investments in AI, and export of physical goods. Our database permits the identification of specific sectors within these activities, and to know which countries specialize in which sectors. If the number of countries active in two sectors, with a possible time delay, is high enough, then we put a link between those sectors. In the example above, many countries (with respect to our null model) are investing in robotics at time t and exporting oil from oil rigs at \(t+\Delta t\). Concrete examples are also reported.
