Platforms and Ecosystems

A “platform” is a business model that utilizes a technological interface to connect two or more distinct but interdependent groups of customers, facilitating value-creating exchanges. For example, Google’s Android, with its Play Store, facilitates interactions between app developers and end users by providing a distribution channel for applications. Simultaneously, it connects hardware manufacturers, who integrate Android into their devices, with consumers seeking a seamless mobile experience. Building on these platforms, “ecosystems” emerge—networks of firms known as “complementors,” which develop complementary products, services, or technologies. In the case of Google’s Android, complementors include app developers, who create software for the platform, and hardware manufacturers, who design devices that run the operating system (OS). These ecosystems are critical to the platform’s success, expanding its offerings and generating powerful network effects, where the value of the platform increases as more users and complementors join. This bibliography begins by discussing existing literature reviews on platforms and ecosystems, shedding light on the key theoretical foundations and empirical studies that have shaped this area of research. It then contrasts platform thinking with product thinking, focusing on the strategic mindset shift required to harness the collaborative potential of platforms. The bibliography proceeds to outline the core players in a platform ecosystem, and the discussion then shifts to the different types of platforms, such as transaction and innovation platforms, and the ways they function in various industries. Next, a key focus is placed on the distinctions between platform and pipeline businesses, with the latter being firms that create value through a linear sequence of activities—from production to distribution to sale—rather than by facilitating interactions between interdependent customer groups. Platforms shift from controlling resources to orchestrating them, leveraging external contributors to co-create value. Competitive advantage moves from internal optimization to fostering interactions among ecosystem participants, driven by network effects. While pipelines rely on supply-side economies of scale, platforms benefit from demand-side economies. Platforms also shift focus from customer value to ecosystem value, using flexible governance that relies on external contributions, and they measure success through ecosystem-level metrics rather than firm-level performance. The bibliography then examines competition within platform ecosystems, discussing how actors participating in a platform ecosystem may end up competing against each other. Next, the article discusses platform performance in terms of both winner-take-all-or-most outcomes and the market value of platforms in today’s economy. Finally, it examines the increasing regulatory scrutiny of platform markets, focusing on how governments and policymakers are addressing issues such as market dominance, data privacy, and the protection of fair competition in a rapidly evolving digital economy.
