The platform ecosystem could generate unlimited innovation with outside complementors and various consumers. Some researchers focused on the competition between two platform ecosystems in the same market and constructed theoretical models of indirect network effects between complementors and consumers. However, the implications from these researche...

Technological platforms such as hardware or systems form platform ecosystems, which are communities orchestrated by platform providers, outside complementors such as software providers, and consumers. Previous studies have suggested that a winner-takes-all situation among platform ecosystems could be induced by interactions between complementors an...

Physical intermediary firms, such as logistics firms, are the foundation of marketplace platform ecosystems.
