Summary. Global innovation networks expanded significantly from 1999 to 2020, becoming more accessible and showing scale-free characteristics. Developed countries in Europe and the United States remain central nodes, though polarization weakened. Four distinct subgroups emerged. Economic and technological factors drive network formation more strongly than demographic factors. China's position strengthened substantially, increasingly serving as a transit hub connecting innovation partners.
