As a consequence, when such firms from larger domestic markets enter export markets, they will be more competitive than competitors coming from smaller markets that have less access to information prior to entering foreign markets. This can partly explain the dominance of Chinese and US firms in digital-intensive sectors, and it also suggests that there is potential for large developing economies to enter digital-intensive sectors. As products are increasingly supplied digitally and GVCs possibly become shorter (see Section C.2(c)), trade will rely less and less on roads, ports, airports or railways, and this would counteract some of the competitiveness gains of high-income countries in digital-intensive sectors and tasks. However, Section C.2(c) also discusses a scenario in which GVCs become longer.
