The article examines digital business ecosystems as subjects of private regulation of consumer behavior. Today, many digital platforms not only connect sellers and buyers but increasingly decide who gains access to the market. Digital platforms now set the terms of market access, determine which goods and services are visible, manage reviews, ratings, bonuses, and user data. Consequently, consumer choice is increasingly shaped not only by personal preferences but also by the rules, algorithms, and incentives embedded in the platform environment. This is particularly evident in markets where consumers interact not with a single service but with an entire network of interconnected services, payments, subscriptions, and personalized offers. The aims of the article are to typologize the mechanisms of private regulation implemented by digital business ecosystems and to identify indicators that capture their effects on consumer markets. The methodological basis of the study is a theoretical and empirical review of Russian and international publications from 2021 to 2026. As a result, the study identifies normativecontrol, technological, economic, datainfrastructural, and reputational mechanisms of platform influence on consumers, revealing how these factors jointly affect attention allocation, choice autonomy, trust, switching costs, and platform market power. The scientific novelty of the article lies in integrating legal, economicsociological, and management approaches to digital platforms into a single analytical framework, as well as in developing a “mechanism–effect–metric” matrix. From a practical standpoint, this research is important because these indicators can be used for empirical studies, help track risks to consumers, and prove useful in discussions on regulatory models for digital platforms.
