Competition Law and Strategic Competition Policy for Denmark’s Digital Future

1. Introduction

Denmark’s digital economy is characterised by extensive use of digital platforms, fintech, e-commerce, cloud services, data-driven business models, digital public infrastructure and highly connected markets. Competition policy therefore has to address not only traditional concerns such as cartels and mergers, but also digital gatekeeping, data advantages, interoperability, algorithms, platform dependency and innovation competition.

The central question is:

How can Denmark preserve open, contestable and innovative digital markets while allowing firms to achieve legitimate efficiencies and scale?

Denmark's competition framework operates principally through the Danish Competition Act, EU competition law under Articles 101 and 102 TFEU, EU merger-control rules, and increasingly the EU's Digital Markets Act (DMA) and other digital regulation.

2. Objectives of Strategic Competition Policy

A strategic competition policy for Denmark's digital future should pursue several interconnected objectives:

Contestable digital markets

Prevention of exclusionary dominance

Protection of innovation competition

Interoperability

Data access and portability

Competitive neutrality

Effective merger control

Prevention of algorithmic collusion

Fair access to digital infrastructure

Protection against ecosystem lock-in

The objective is not to prevent successful digital firms from becoming large. Rather, the competition-law concern arises where market power is maintained or extended through exclusionary conduct rather than competition on the merits.

3. Denmark's Legal Framework

A. Danish Competition Act

The Danish Competition Act broadly prohibits:

agreements restricting competition;

concerted practices;

abuse of dominant position;

anti-competitive mergers and concentrations.

The Danish Competition and Consumer Authority and the Danish Competition Council play important enforcement roles.

B. Article 101 TFEU

Article 101 addresses agreements and concerted practices that restrict competition.

Digital examples include:

algorithmic price coordination;

platform parity clauses;

information exchange;

marketplace restrictions;

geographic allocation;

coordinated restrictions on suppliers.

C. Article 102 TFEU

Article 102 addresses abuse of dominance.

Potential digital abuses include:

self-preferencing;

tying;

discriminatory access;

refusal to provide interoperability;

exclusionary rebates;

leveraging;

exploitative conditions.

D. EU Digital Markets Act

The DMA adds a regulatory layer for designated gatekeepers.

It addresses practices including:

self-preferencing;

combining personal data in certain circumstances;

restrictions on business-user access;

interoperability;

data portability;

restrictions on alternative payment systems;

anti-steering restrictions.

The DMA is particularly significant for Denmark because digital markets are increasingly cross-border and many major platforms operate throughout the EU.

4. Strategic Competition Policy in Digital Markets

Traditional competition policy often asks:

Is the firm dominant?

Digital competition policy increasingly asks:

What allows the firm to remain unavoidable?

Relevant sources of durable digital power include:

network effects;

economies of scale;

data accumulation;

switching costs;

interoperability barriers;

ecosystem effects;

default settings;

app-store control;

cloud dependency;

digital identity;

payment infrastructure.

5. Network Effects

Digital platforms frequently become more valuable as more users join.

For example:

More users → more sellers → more products → more consumers → more sellers.

This can create rapid concentration.

A Danish competition policy must therefore distinguish between:

Competition through scale

Legitimate growth resulting from better products.

Entrenchment through exclusion

Growth maintained by preventing competitors from achieving comparable scale.

The second situation creates stronger competition-law concerns.

6. Data as a Source of Market Power

Data can provide competitive advantages through:

better algorithms;

targeted advertising;

fraud detection;

recommendation systems;

personalised services;

credit assessment;

demand forecasting.

A dominant platform may accumulate data across multiple markets.

The competition concern becomes particularly significant when competitors cannot obtain comparable data or when data is used to reinforce dominance in another market.

7. Interoperability as Competition Policy

Interoperability is strategically important for Denmark's digital future.

Examples include:

banking APIs;

payment systems;

cloud services;

messaging;

digital identity;

smart-city infrastructure;

healthcare technology;

energy systems.

Interoperability can reduce:

switching costs;

network effects;

ecosystem lock-in.

It can therefore make digital markets more contestable.

8. Case Law

1. Microsoft Corp. v Commission, Case T-201/04

Facts

The European Commission found Microsoft dominant in PC operating systems and abusive conduct involving interoperability information and the Windows Media Player.

Principle

A dominant technology firm may face competition-law obligations where its control over an important technological ecosystem is used to restrict interoperability or extend dominance.

Relevance to Denmark

The case is highly relevant to:

cloud ecosystems;

operating systems;

smart-city platforms;

digital public infrastructure.

A dominant digital infrastructure provider should not necessarily be able to make its ecosystem technically inaccessible to competitors.

9. Google Search (Shopping), Case T-612/17

Facts

The European Commission found that Google systematically favoured its comparison-shopping service in search results.

The General Court upheld the Commission's decision in substance.

Principle

A dominant search platform can face competition scrutiny where it gives preferential treatment to its own service and disadvantages competing services.

Relevance

The case illustrates the importance of:

ranking neutrality;

platform self-preferencing;

visibility;

access to consumer traffic.

For Denmark's digital economy, similar concerns could arise in marketplaces, travel platforms, food-delivery platforms and other digital intermediaries.

10. Google Android, Case T-604/18

Facts

The European Commission examined Google's conduct concerning Android, including arrangements concerning search, browsers and app distribution.

Principle

A dominant ecosystem operator may unlawfully reinforce dominance through contractual and technological arrangements that restrict competition from competing services.

Relevance

The case demonstrates the importance of preventing digital ecosystems from becoming closed environments.

It is particularly relevant to:

mobile applications;

digital payments;

app stores;

operating systems;

alternative digital services.

11. Intel v Commission, Case C-413/14 P

Facts

The case concerned Intel's rebate arrangements and the question whether those arrangements were capable of excluding competitors.

Principle

Competition analysis of exclusionary conduct by a dominant undertaking requires attention to the actual or potential competitive effects of the conduct.

Relevance to Denmark

Digital companies frequently use:

discounts;

preferential commissions;

loyalty arrangements;

platform incentives;

exclusive contracts.

Competition authorities must distinguish legitimate commercial discounts from strategies capable of excluding equally efficient competitors.

12. Deutsche Telekom v Commission, Case C-280/08 P

Facts

The case involved pricing conditions imposed by Deutsche Telekom in telecommunications markets.

Principle

A dominant infrastructure operator may engage in abusive conduct through pricing structures that make effective downstream competition difficult.

Relevance

The principle can extend conceptually to digital infrastructure such as:

cloud platforms;

telecom networks;

payment infrastructure;

digital advertising infrastructure.

Where a firm controls an upstream bottleneck and competes downstream, pricing can become a mechanism of foreclosure.

13. Slovak Telekom v Commission, Case C-165/19 P

Facts

The case concerned access to telecommunications infrastructure and exclusionary conduct.

Principle

A dominant undertaking controlling important infrastructure may face competition-law scrutiny where its conduct restricts downstream competitors.

Relevance

This is important for Denmark's digital infrastructure because telecommunications, cloud connectivity and digital services increasingly operate as interconnected ecosystems.

The case demonstrates why access and interoperability remain central to digital competition.

14. Bronner v Mediaprint, Case C-7/97

Facts

The dispute concerned access to a newspaper distribution network.

Principle

A refusal to provide access to infrastructure controlled by a dominant undertaking does not automatically constitute abuse.

The strict essential-facilities doctrine requires genuine indispensability and the absence of realistic alternatives, among other considerations.

Relevance

This is an important counterbalance.

Strategic competition policy should not force every successful digital company to open every component of its technology to competitors.

There must be a careful distinction between:

legitimate proprietary innovation; and

control of an indispensable bottleneck.

15. United States v Microsoft Corp., 253 F.3d 34 (D.C. Cir. 2001)

Facts

Microsoft's conduct concerning Internet Explorer, Windows and competing browser technologies was examined under U.S. antitrust law.

Principle

A monopolist may violate antitrust law when it uses control over a platform to restrict technologies that threaten its position.

Relevance

The case remains useful for understanding platform competition.

For Denmark, analogous issues can arise where a dominant digital ecosystem controls:

operating systems;

default settings;

application distribution;

APIs;

digital identity;

cloud interfaces.

16. Apple and App-Store Competition

European competition enforcement concerning Apple's App Store practices also illustrates a central digital-policy issue: control over an app-distribution ecosystem can give a platform significant power over downstream businesses.

Competition concerns may include:

payment restrictions;

anti-steering provisions;

commissions;

restrictions on alternative distribution;

discriminatory access.

The policy significance for Denmark is that many Danish digital businesses depend upon global app ecosystems. Thus, the competitive conditions facing Danish firms may be determined partly by platforms operating outside Denmark.

17. Digital Gatekeepers and Denmark

One of the most important strategic developments is the emergence of gatekeeper regulation.

A gatekeeper can control access to:

consumers;

app users;

advertisers;

business users;

search traffic;

digital payment systems;

operating systems.

This creates a structural problem:

Danish businesses may be formally independent competitors but economically dependent upon foreign digital gatekeepers.

Competition policy therefore needs to address both:

local competition and cross-border platform dependency.

18. Strategic Autonomy and Competition

Denmark may have legitimate strategic interests in maintaining resilient digital infrastructure.

These can include:

cybersecurity;

digital infrastructure;

cloud capacity;

payment systems;

telecommunications;

AI;

data infrastructure.

However, strategic autonomy should not automatically mean protectionism.

Competition policy should avoid simply replacing foreign dominance with domestic monopoly.

A competitive strategic-autonomy model would instead promote:

multiple suppliers;

interoperability;

portability;

open standards;

contestable procurement;

competitive neutrality.

19. Digital Mergers

Merger control becomes particularly important because digital acquisitions may involve valuable assets that are not reflected in conventional turnover.

A startup may have:

few revenues;

important technology;

valuable data;

strong network effects;

significant innovation potential.

A larger platform acquiring that startup could eliminate a future competitive threat.

Therefore, strategic merger analysis should consider:

Current competition

Who competes today?

Potential competition

Who could compete tomorrow?

Innovation competition

Which technologies could challenge existing firms?

Data competition

Does the transaction combine unique datasets?

Ecosystem competition

Does it strengthen an existing digital ecosystem?

20. Algorithmic Competition

Algorithms can facilitate:

independent price optimisation;

personalised pricing;

inventory management;

fraud detection.

These uses can be pro-competitive.

But algorithms may also facilitate:

collusion;

market allocation;

coordinated pricing;

discriminatory access.

The critical question is not:

“Was an algorithm used?”

It is:

“Did the algorithm facilitate conduct that competition law prohibits?”

21. Algorithmic Collusion

Consider four Danish online retailers using software that automatically observes competitors' prices.

If the systems independently optimise prices, that is not automatically unlawful.

But competition concerns become greater where firms:

communicate their pricing intentions;

agree on common parameters;

use a common algorithm to coordinate;

exchange competitively sensitive information;

intentionally design systems to sustain supracompetitive prices.

The traditional prohibition against anti-competitive coordination remains applicable even where coordination occurs digitally.

22. Cloud Computing and Competition

Cloud infrastructure is strategically important because businesses may depend upon:

computing capacity;

storage;

software;

databases;

AI infrastructure.

Potential competition concerns include:

switching costs;

technical lock-in;

data portability problems;

interoperability restrictions;

tying;

preferential treatment of affiliated services.

Competition policy should therefore encourage multi-cloud and interoperability where economically and technically feasible.

23. Fintech and Digital Payments

Denmark's sophisticated digital economy makes payment infrastructure particularly important.

Competition concerns may arise where a platform controls:

payment initiation;

digital wallets;

authentication;

transaction data;

merchant access.

Potential issues include:

exclusion of competing payment providers;

tying;

discriminatory access;

excessive fees;

data advantages.

24. Digital Public Infrastructure

Public digital systems can also raise competition issues when public infrastructure interacts with private markets.

Examples:

digital identity;

public payment infrastructure;

government data platforms;

digital procurement platforms;

health-data infrastructure.

The principle of competitive neutrality is important.

Public infrastructure should not unnecessarily favour one commercial provider where alternative providers can compete safely and effectively.

25. Competition and Artificial Intelligence

AI introduces several emerging concerns:

Data concentration

Large firms may possess superior datasets.

Compute concentration

Advanced AI may depend upon scarce computing resources.

Foundation-model concentration

A small number of firms may control foundational AI systems.

Distribution concentration

AI systems may be integrated into dominant search, operating-system or cloud ecosystems.

Vertical integration

Cloud providers may simultaneously supply:

computing;

foundation models;

application stores;

AI applications.

Competition policy must therefore examine whether integration creates foreclosure opportunities.

26. Danish SMEs and Platform Dependency

Small Danish businesses may rely upon:

search engines;

marketplaces;

app stores;

social media;

cloud providers;

digital advertising.

This creates a platform dependency problem.

Competition policy should therefore consider whether SMEs have:

reasonable switching opportunities;

access to their own data;

alternative distribution channels;

transparent platform rules;

fair contractual conditions.

27. Public Procurement as a Competition Tool

Denmark can also use public procurement strategically.

Large public procurement contracts can influence market structure.

Poorly designed procurement can create:

incumbent lock-in;

vendor dependence;

barriers to entry;

interoperability problems.

Competition-friendly procurement can instead encourage:

modular contracts;

interoperability;

multiple suppliers;

open technical standards;

portability;

competitive tendering.

28. Competition Governance Model for Denmark's Digital Future

A useful strategic framework is:

Pillar 1 — Contestability

Can new firms realistically enter?

Pillar 2 — Interoperability

Can competing systems communicate?

Pillar 3 — Portability

Can businesses and consumers move their data?

Pillar 4 — Neutrality

Are infrastructure and platforms treating competing businesses fairly?

Pillar 5 — Innovation

Does market structure preserve incentives for technological development?

Pillar 6 — Merger Control

Are emerging competitive threats being preserved?

Pillar 7 — Algorithmic Accountability

Can competition authorities understand and test automated market behaviour?

Pillar 8 — Cross-Border Enforcement

Can Danish authorities cooperate effectively with EU institutions?

29. Strategic Competition Policy: A Balanced Approach

Denmark should distinguish between three categories.

30. Key Principles from the Case Law

The cases demonstrate several principles relevant to Denmark's digital future:

Microsoft — platform control can be used to exclude technological competitors.

Google Shopping — search and ranking systems can affect competition between platforms.

Google Android — ecosystem arrangements can reinforce dominance.

Intel — exclusionary conduct should be assessed through its competitive effects.

Deutsche Telekom — control of infrastructure can affect downstream competition through pricing.

Slovak Telekom — access to important infrastructure can be central to effective competition.

Bronner — access obligations should remain carefully constrained where infrastructure is not genuinely indispensable.

U.S. Microsoft — platform power can create competitive concerns where a dominant ecosystem is used to suppress emerging technological threats.

31. Exam-Ready Conclusion

Strategic competition policy for Denmark's digital future requires a shift from purely traditional market-share analysis toward a broader examination of contestability, ecosystem power, data, interoperability, algorithms, infrastructure and innovation.

Denmark's competition authorities must preserve the benefits of digital scale while preventing dominant firms from using control over critical digital gateways to foreclose competitors. EU competition law, the Danish Competition Act and the Digital Markets Act provide complementary tools for achieving this objective.

The key challenge is especially significant because many digital markets used by Danish consumers and businesses are cross-border markets. A Danish firm's competitive position may depend upon access to a global app store, cloud provider, search engine, advertising platform or payment ecosystem.

Accordingly, effective strategic competition policy should promote:

contestability + interoperability + data portability + competitive neutrality + innovation + effective merger control + algorithmic accountability.

The ultimate objective should not be to prevent large digital firms from succeeding, but to ensure that success remains contestable and that today's digital infrastructure does not become tomorrow's permanent competitive bottleneck.
