1. Introduction

Competition law and theories of ecosystem governance examine how economic power, decision-making authority, access rules, and competitive relationships operate within interconnected markets. The concept is particularly important in digital markets, where a single business may control an operating system, an application store, a payment service, advertising infrastructure, data resources, and customer access.

However, ecosystem governance is not limited to technology. It also applies to banking networks, telecommunications, energy markets, logistics, healthcare, financial services, manufacturing, and public-private commercial networks.

The central question is whether the rules governing an economic ecosystem facilitate fair participation, innovation, and efficient coordination, or allow a powerful participant to restrict competition and entrench its market position.

Competition law does not require every business in an ecosystem to have identical market power. Rather, it seeks to prevent legally prohibited agreements, exclusionary conduct, anticompetitive mergers, and other practices that undermine competitive markets.

The European Union's litigation concerning Google's Android ecosystem illustrates this relationship: the General Court expressly considered the concepts of a multisided platform and an ecosystem in assessing contractual restrictions, product bundling, and alleged exclusionary effects.

2. Meaning of ecosystem governance

An economic ecosystem is a network of interconnected firms, consumers, suppliers, intermediaries, developers, infrastructure providers, and other participants whose activities affect one another.

Ecosystem governance refers to the rules, mechanisms, and institutions through which these participants interact. It determines matters such as:

Who may enter and participate in the ecosystem.

How participants obtain access to infrastructure, data, customers, and distribution.

Whether members can develop complementary products and services.

How prices, commissions, technical standards, and contractual conditions are determined.

How disputes are resolved and decisions are reviewed.

Whether the ecosystem's controlling firm competes with participants that depend on its services.

For example, an application-store operator may simultaneously provide infrastructure to developers, establish rules for distributing applications, collect commissions, and compete against those developers through its own applications.

Such an arrangement may generate efficiencies and a convenient user experience. It may also create a conflict of interest if the operator uses its governance powers to disadvantage competing applications.

Principal forms of ecosystem governance

1. Digital ecosystem governance

Operating systems, application stores, search engines, cloud services, social networks, online marketplaces, and digital payment systems establish technical and commercial rules for participants.

2. Industrial and supply-chain governance

Manufacturers, suppliers, distributors, logistics providers, and retailers coordinate production, standards, access, and distribution.

3. Financial ecosystem governance

Banks, payment networks, fintech companies, merchants, and financial infrastructure providers establish interoperability, access, settlement, and security requirements.

4. Infrastructure ecosystem governance

Telecommunications, energy, transport, and other infrastructure operators determine how businesses obtain access to essential networks and facilities.

These arrangements differ in their economic characteristics and legal obligations. Their common feature is that governance rules can influence the ability of independent participants to compete.

3. Major theories of ecosystem governance

A. Transaction cost economics

Transaction cost economics, associated with Ronald Coase and Oliver Williamson, explains why firms develop internal hierarchies, long-term contracts, and coordinated networks rather than relying exclusively on independent market transactions.

In an ecosystem, centralized governance can reduce the costs of negotiating contracts, maintaining compatibility, preventing fraud, and coordinating technical development.

Competition-law implication: A common set of rules can improve efficiency, but a controlling firm may also impose restrictions that prevent participants from dealing with rival providers.

Authorities should examine whether restrictions are reasonably related to legitimate objectives and whether their competitive effects are consistent with applicable law.

B. Network effects theory

Network effects arise when the value of a service to a user depends partly on the number of other users or participants.

For example, an online marketplace may become more attractive as it attracts more sellers and buyers. A payment network may become more useful as more merchants accept it.

Network effects can support rapid growth and substantial consumer benefits. However, they may also produce a feedback loop in which established platforms become increasingly difficult to challenge.

Competition-law implication: Authorities should investigate whether network effects, switching costs, data advantages, and barriers to entry protect a dominant business from effective competitive pressure.

A large user base alone does not establish an infringement. The inquiry concerns market power, conduct, and legally relevant competitive effects.

C. Platform governance theory

Platform governance concerns how an intermediary establishes and enforces the rules under which different groups interact.

A platform may determine admission criteria, ranking methods, commission rates, technical standards, data access, and dispute-resolution procedures.

This creates a distinctive governance problem when the platform acts simultaneously as:

An infrastructure provider.

A regulator of participation within its own network.

A commercial competitor to businesses using that network.

Competition-law implication: Self-preferencing, discriminatory access, tying, exclusionary contractual terms, and restrictions on alternative distribution channels may require scrutiny, depending on the applicable legal framework and market circumstances.

D. Property rights and control theory

Property rights theory emphasizes how ownership and control of assets influence economic incentives. In ecosystems, these assets may include software interfaces, patents, customer relationships, data, distribution networks, and technical infrastructure.

A business that controls a critical asset may possess substantial influence over complementary businesses that depend on it.

Competition-law implication: Control over an asset is not unlawful by itself. The concern arises when an acquisition or the exercise of control violates merger rules, abuse-of-dominance provisions, or other applicable competition requirements.

E. Institutional economics and polycentric governance

Institutional economics examines how formal laws, private rules, industry standards, contracts, and dispute-resolution mechanisms shape economic activity.

Polycentric governance involves multiple decision-making centres rather than a single authority. An ecosystem may be governed simultaneously by competition regulators, sectoral regulators, courts, standards bodies, and private contractual institutions.

Competition-law implication: Effective governance requires coordination between these institutions without allowing private rules to undermine statutory competition protections. Transparent procedures and meaningful review can help prevent arbitrary exclusion.

F. Resource dependence theory

Resource dependence theory examines how an organization relies on resources controlled by other organizations.

Within an ecosystem, a smaller firm may depend on a major platform for customer access, cloud hosting, distribution, data, or payment processing.

The more difficult these resources are to replace, the greater the potential bargaining power of the controlling firm.

Competition-law implication: Authorities should investigate whether access restrictions or contractual conditions are capable of foreclosing competing firms. Dependence alone does not prove unlawful conduct, but it may be important evidence of the commercial effects of a challenged practice.

G. Governance of the commons

The governance-of-the-commons approach examines how shared resources can be managed through rules that prevent overuse and encourage cooperation.

Shared technical standards, open-source software, research infrastructure, and interoperable networks can function as common resources for participating businesses.

Competition-law implication: Joint governance may encourage innovation, but standard-setting and industry cooperation can also exclude particular firms, restrict competing technologies, or facilitate collusion. Competition analysis must distinguish legitimate cooperation from unlawful restrictions.

H. Dynamic competition and innovation theory

Dynamic competition focuses on how businesses compete through research, experimentation, new technologies, and emerging business models.

An ecosystem may provide a foundation on which independent innovators develop complementary products. At the same time, the ecosystem owner may have incentives to acquire, imitate, or disadvantage emerging rivals.

Competition-law implication: Merger review and abuse-of-dominance analysis may need to consider future competition, innovation incentives, and the possibility that a currently small participant could become a significant competitor.

4. At least 8 important case laws on ecosystem governance

The following decisions illustrate how courts and competition authorities have addressed platform control, interoperability, access restrictions, self-preferencing, and the competitive consequences of ecosystem governance. Some are direct ecosystem cases; others establish principles relevant by analogy.

Case 1. Google LLC and Alphabet Inc. v European Commission — Google Android (2022)

Court: General Court of the European Union
Case: T-604/18, judgment of 14 September 2022

Facts: The European Commission challenged Google's contractual arrangements involving Android device manufacturers and mobile network operators. The challenged practices included restrictions concerning pre-installation of Google applications, exclusive pre-installation incentives, and anti-fragmentation obligations affecting alternative versions of Android.

Legal issue: Whether Google's contractual arrangements, considered within the Android ecosystem, constituted an abuse of a dominant position under Article 102 TFEU.

Decision: The General Court largely upheld the Commission's findings, while annulling the decision in part concerning the assessment of certain exclusive payments and adjusting the fine. The judgment expressly addressed the concepts of multisided platforms and ecosystems.

Ecosystem governance principle: A platform owner may establish technical and commercial rules, but contractual conditions can become problematic where they restrict alternative products, operating systems, or distribution channels and reinforce an established market position.

Significance: This is a leading illustration of the relationship between ecosystem governance and competition law. It demonstrates why an authority may need to assess interconnected products and contractual arrangements together rather than examining each restriction in isolation.

Case 2. Microsoft Corp. v Commission (2007)

Court: Court of First Instance of the European Communities
Case: T-201/04, judgment of 17 September 2007

Facts: The European Commission challenged Microsoft's refusal to provide certain interoperability information to competitors and its tying of Windows Media Player to the Windows operating system.

Legal issue: Whether Microsoft had abused its dominant position by using control over a widely used operating system to restrict competition in related software markets.

Decision: The Court largely upheld the Commission's decision, including the findings concerning interoperability and tying.

Ecosystem governance principle: Control over a foundational technology can influence the competitive opportunities of businesses that depend on it. Interoperability rules can therefore be important to the functioning of an ecosystem.

Significance: The case shows that technical compatibility and access rules are not merely engineering questions. Where a dominant firm controls an important technological gateway, its decisions can shape the development of complementary products and services.

Case 3. Google LLC and Alphabet Inc. v European Commission — Google Shopping (2021)

Court: General Court of the European Union
Case: T-612/17, judgment of 10 November 2021

Facts: The European Commission found that Google had favoured its own comparison-shopping service in general search results while applying less favourable treatment to competing comparison-shopping services.

Legal issue: Whether the treatment of Google's own service and competing services amounted to an abuse of dominance.

Decision: The General Court largely upheld the Commission's decision.

Ecosystem governance principle: A company that controls an important intermediary may influence competition by determining how its own products and independent rivals are displayed, ranked, or accessed.

Significance: The case is central to discussions of self-preferencing. It illustrates the potential conflict between a platform's role as an intermediary and its role as a competitor within the same ecosystem.

The decision does not mean that every preference for a platform's own product is unlawful. The applicable legal test and the evidence of exclusionary effects remain important.

Case 4. United States v. Microsoft Corp. (2001)

Court: United States Court of Appeals for the District of Columbia Circuit
Citation: 253 F.3d 34 (D.C. Cir. 2001)

Facts: The US government challenged Microsoft's conduct in the market for personal-computer operating systems, including its treatment of browser competition and its agreements with computer manufacturers and other businesses.

Legal issue: Whether Microsoft had unlawfully maintained its operating-system monopoly through exclusionary conduct.

Decision: The Court of Appeals affirmed important findings of unlawful monopolization but reversed or remanded other aspects of the district court's judgment, including the breakup remedy.

Ecosystem governance principle: A firm controlling a foundational platform may have the ability and incentive to use contractual arrangements or technical restrictions to protect its position against emerging competitive threats.

Significance: The case demonstrates the importance of evaluating how technical integration, contractual relationships, and control over distribution interact. It also illustrates that legitimate product development must be distinguished from conduct that unlawfully maintains monopoly power.

Case 5. Ohio v. American Express Co. (2018)

Court: Supreme Court of the United States
Citation: 585 U.S. 529 (2018)

Facts: The case concerned anti-steering provisions in American Express's merchant agreements. These provisions restricted merchants from encouraging customers to use competing payment cards.

Legal issue: How competition should be assessed in a two-sided transaction platform that connects merchants and cardholders.

Decision: The Supreme Court held that the plaintiffs had not established the required anticompetitive effects under the applicable analysis of the two-sided transaction platform.

Ecosystem governance principle: In certain multisided platforms, the competitive effects on one group of participants cannot be adequately understood without considering the platform's effects on the other side.

Significance: The case highlights the importance of network effects and cross-platform interactions. It cautions against analysing a platform's rules in isolation when the business model depends on balancing the interests of interconnected user groups.

The ruling is specific to the US antitrust framework and does not establish that every platform restriction is lawful.

Case 6. Epic Games, Inc. v. Apple Inc. (2021)

Court: United States District Court, Northern District of California
Citation: 559 F. Supp. 3d 898 (N.D. Cal. 2021)

Facts: Epic Games challenged Apple's App Store rules, including restrictions concerning alternative payment mechanisms and the distribution of applications on iOS devices.

Legal issue: Whether Apple's app-distribution and payment rules violated US antitrust law or other applicable legal requirements.

Decision: The district court rejected most of Epic's federal antitrust claims, finding that Epic had not established the required monopoly or attempted-monopolization liability under the theories presented. It nevertheless found Apple's anti-steering provisions violated California's Unfair Competition Law and issued an injunction addressing those provisions.

Ecosystem governance principle: An ecosystem operator's control over app distribution and payment rules raises questions about access, competition, consumer choice, and the ability of developers to communicate alternative purchasing options.

Significance: The case illustrates the tension between platform security, integrated user experience, commercial control, and independent developer freedom. It also shows that different legal doctrines can produce different outcomes within the same dispute.

Case 7. Epic Games, Inc. v. Apple Inc. — Ninth Circuit appeal (2023)

Court: United States Court of Appeals for the Ninth Circuit
Citation: 67 F.4th 946 (9th Cir. 2023)

Facts: Epic appealed the district court's judgment concerning Apple's App Store policies and the applicable antitrust and state-law claims.

Legal issue: Whether the district court had correctly applied the relevant legal standards to Apple's ecosystem restrictions and Epic's claims.

Decision: The Ninth Circuit largely affirmed the district court's judgment, including the disposition of the principal federal antitrust claims and the injunction concerning anti-steering provisions.

Ecosystem governance principle: Competition analysis must distinguish between restrictions that are established to violate a particular legal rule and restrictions that are commercially restrictive but do not satisfy the applicable test for antitrust liability.

Significance: Read together, the district court and appellate decisions provide an important case study in the limits of competition-law intervention in integrated digital ecosystems.

Case 8. Aspen Skiing Co. v. Aspen Highlands Skiing Corp. (1985)

Court: Supreme Court of the United States
Citation: 472 U.S. 585 (1985)

Facts: Aspen Skiing Company controlled three of the four major ski areas in Aspen, Colorado. It discontinued a joint, multi-area lift-ticket arrangement with its smaller competitor, Aspen Highlands, and rejected alternatives that had previously supported cooperation.

Legal issue: Whether the dominant firm's refusal to continue a profitable course of dealing could constitute monopolization under Section 2 of the Sherman Act.

Decision: The Supreme Court upheld the finding of unlawful monopolization on the particular facts.

Ecosystem governance principle: Cooperation between independent firms can create value for customers. A dominant participant's termination of an established cooperative arrangement may raise concerns when the evidence supports an inference of exclusionary conduct rather than ordinary commercial decision-making.

Significance: Although not a digital-platform case, the decision is relevant to ecosystem access and interoperability disputes. It illustrates the importance of examining prior dealings, commercial incentives, and the competitive significance of denying access to a jointly provided service.

The case is narrow and does not establish a general duty for dominant firms to cooperate with competitors.

Comparative case-law table

5. Application under Indian competition law

The theories of ecosystem governance can be applied to the Competition Act, 2002, particularly where businesses control digital platforms, distribution channels, payment networks, or other interconnected markets.

A. Section 3 — Anti-competitive agreements

Section 3 addresses agreements that cause or are likely to cause an appreciable adverse effect on competition in India.

In ecosystem governance, relevant arrangements may include:

Agreements among competitors to restrict entry or coordinate prices.

Exclusive supply or distribution arrangements that restrict competing firms.

Contractual restrictions imposed on developers, sellers, or distributors.

Cooperation agreements that may facilitate innovation but also restrict competition.

The legal assessment depends on the nature of the agreement, the applicable statutory provisions, and its competitive effects.

B. Section 4 — Abuse of dominant position

Section 4 prohibits the abuse of a dominant position. It is particularly relevant when a powerful ecosystem operator controls access to customers, essential infrastructure, distribution channels, or complementary services.

Potential concerns include:

Unfair or discriminatory conditions imposed on participants.

Denial of market access.

Tying or bundling that unlawfully restricts competition.

Practices that protect dominance in one market by restricting competition in another.

Restrictions on technical development or commercial opportunities.

Dominance alone is not prohibited. The relevant question is whether the business has engaged in conduct that amounts to abuse under the Act.

C. Sections 5 and 6 — Combinations

Sections 5 and 6 regulate combinations, subject to the applicable statutory thresholds and requirements.

In an ecosystem context, merger analysis may need to consider whether a transaction combines control over:

A major platform and an emerging competitor.

Infrastructure and complementary services.

Data resources and distribution networks.

Competing businesses operating at different levels of a supply chain.

The analysis should consider the potential effects on entry, innovation, foreclosure, and competitive constraints, alongside substantiated efficiencies.

D. Section 18 — Duties of the Competition Commission of India

Section 18 sets out the CCI's duties, including eliminating practices having adverse effects on competition, promoting and sustaining competition, protecting consumers, and ensuring freedom of trade carried on by other participants in markets in India.

These objectives are relevant when private ecosystem rules influence how independent businesses participate in a market.

E. Sections 19 and 20 — Assessment and combinations inquiry

Section 19 provides for inquiries into specified competition concerns and identifies relevant factors for assessing adverse effects on competition. Section 20 addresses inquiries into combinations.

These provisions are important for evaluating market structure, barriers to entry, foreclosure, efficiencies, and other relevant competitive conditions.

The precise legal outcome depends on the statutory requirements and facts of each case.

6. Principles of effective ecosystem governance

A competition-compliant ecosystem should establish governance rules that enable efficient coordination without unnecessarily restricting independent competition.

1. Fair and transparent access

Admission, distribution, and participation rules should have legitimate objectives and should not be used to unlawfully exclude competing businesses.

2. Interoperability

Where appropriate, technical standards should permit compatible products and services to interact, while accounting for security, privacy, and legitimate intellectual-property interests.

3. Non-discriminatory treatment

Comparable participants should not be disadvantaged without an objectively defensible basis where the applicable law prohibits such discrimination.

4. Accountability and review

Participants should have meaningful procedures for challenging account suspensions, access decisions, technical restrictions, and contractual disputes.

5. Innovation and independent entry

Governance arrangements should preserve opportunities for new firms and complementary innovators to compete, subject to legitimate commercial and technical constraints.

These are policy principles, not universal legal obligations in every market. Their application depends on the relevant jurisdiction and the nature of the ecosystem.

7. Major challenges in ecosystem governance

7.1 Concentration of decision-making power

An ecosystem owner may control the rules governing participation while also competing with participants. This creates potential conflicts of interest, particularly where businesses depend on the owner for distribution or infrastructure.

7.2 Information asymmetry

The platform operator may possess extensive information about customer behaviour, transaction patterns, pricing, and demand. Independent participants may lack equivalent information or the ability to verify how decisions are made.

7.3 Network effects and barriers to entry

Network effects can create substantial value but may also make it difficult for a new entrant to attract enough users to compete with an established ecosystem.

7.4 Rapid technological change

Traditional market definitions may become less reliable where services converge, new technologies emerge, or firms compete through innovation rather than price alone.

7.5 Balancing regulation and innovation

Overly intrusive regulation may weaken incentives to invest, develop secure systems, or introduce new products. Insufficient intervention may allow an established ecosystem to restrict competition and entrench market power.

8. Policy recommendations

Effective competition policy for ecosystems should:

Evaluate how governance rules affect independent participants and end users.

Examine the economic justification for exclusionary restrictions.

Assess market power across interconnected services where the evidence supports such an approach.

Protect legitimate innovation, security, and investment incentives.

Investigate mergers that may eliminate emerging competitive threats.

Encourage appropriate interoperability and fair access where supported by law and economic evidence.

Coordinate competition enforcement with sectoral regulation when necessary.

Ensure that remedies are proportionate, enforceable, and directed at the identified competitive harm.

9. Conclusion

Competition law and theories of ecosystem governance explain how power, rules, access, and incentives shape competition among interconnected businesses. Transaction cost economics explains the benefits of coordination; network effects theory explains the growth and persistence of platforms; resource dependence theory highlights participant vulnerability; and institutional economics explains the importance of transparent, accountable governance.

The cases involving Google, Microsoft, Apple, American Express, and Aspen Skiing demonstrate that ecosystem governance can raise questions about interoperability, self-preferencing, contractual restrictions, platform access, and cooperation between competitors.

The central legal principle is that ecosystem control is not inherently unlawful, but it must not be used in ways that violate applicable competition law. The goal is to preserve the benefits of integrated systems while protecting competitive opportunities, consumer choice, innovation, and fair access to markets.
