The platform as ecosystem: Configurations and dynamics of governance and power

Abstract

Digital ‘platforms’ owned and operated by powerful Big Tech companies have shaped and impacted social, economic, and political life in significant ways. Yet, platforms remain an ambiguous phenomenon. What exactly are these platforms? How can we identify and understand the features of their power? The platform as ecosystem explains how not merely the platforms themselves but especially their larger ‘ecosystems’ are important for understanding the unique features of platform governance and power. Platform ecosystems have become the dominant technological, organisational, and governance model for digital platforms over the past fifteen years. These ecosystems comprise many different types of users including end-consumers, software developers, marketers and advertisers, and business partners who build software tools, products, and services of their own ‘on top’ of the interfaces provided and controlled by leading platforms. These users each help build and expand platform ecosystems while negotiating governance and control by central platforms. This dissertation examines different aspects of platform ecosystems to determine how platforms’ material foundations or infrastructures relate to governance and power. It develops several novel empirical and historical approaches for studying the distinct material and relational features of digital platform ecosystems. This reveals how platforms derive considerable power from their ecosystems and provides unique empirical and historical insights into the technological, organisational, and evolutionary features of platform (and mobile app) ecosystems. These approaches and insights are relevant to digital media and platform researchers and help policymakers, regulators, and authorities worldwide dealing with the challenges of governing digital economies and societies.
