Evolución del comercio electrónico B2B en el comercio internacional: un estudio documental sobre la intermediación comercial y las cadenas de distribución global (2020-2026)

Business-to-business (B2B) electronic commerce has reconfigured commercial intermediation structures and global distribution chains. This documentary study, qualitative in nature, analyzes how digital platforms have altered intermediation models and distribution dynamics in international B2B trade between 2020 and 2026. Based on a systematic review of academic literature and institutional sources, the processes of disintermediation and reintermediation were examined. The findings suggest that digital platforms have reduced barriers to accessing international markets, enabling smaller firms to participate in global supply chains previously reserved for large corporations. However, disintermediation has not implied the disappearance of intermediaries, but rather their transformation into new forms of digital intermediation that add value through data management, trust building, and logistics integration. It is concluded that B2B electronic commerce has redefined the value criteria of commercial intermediation.
