1. Introduction
Multi-sided platforms enabled by digital technologies are a dominant business model in the global economy. They have enabled new ways for individuals and companies alike to create, deliver and capture value by facilitating connections between two or more sides and fostering innovation [
1].
Their widespread adoption across industries, such as transportation (Uber, blablacar), accommodation (Airbnb), food (TooGoodToGo) and technology (Amazon AWS) can be attributed to network effects, an inherent characteristic of platforms, which arise when users create value for other users [
2]. The economic value they create is evidenced by their positioning in the global market, where four out of the top five most valuable companies are digital platforms with data-driven business models [
3].
Scholars within economics, innovation and information systems seeking to understand the ubiquitous platforms, have studied the core strategy concepts [
4,
5,
6,
7,
8] and proposed different platform architectures [
9,
10,
11]
While platform research has largely focused on the strategic decisions for successfully launching and scaling a business platform in the economic sense, this paper finds that the sustainability angle of platforms has so far been overlooked.
When looking into sustainable business models [
12], business models for sustainability BMfS [
13] and business models for sustainable innovation [
14] literature, efforts have been dedicated to understanding what kind of sustainable business models exist where the value creation logic integrates a social or ecological value at its core. Yet, their study focusing on designing platform business architectures in more sustainable ways is not clear. Therefore, this paper takes an integrated perspective combining both phenomena answering two questions:
What are the available business model design choices of platforms for sustainability? Are there fundamental design parameters which characterize platforms for sustainability in comparison to platforms without a sustainability angle?
The paper proceeds as follows. It starts by providing an overview of the methodology, followed by a review of platform literature as well as sustainable business research. In a third step, it presents the results of the morphological analysis which allocates key decisions on value creation, delivery and capture that are key to platforms. In a fourth step, it classifies the identified cases employing a qualitative content analysis and codifies them with regard to the selected variables. Finally, design strategies supporting the development of platforms for sustainability are discussed.
2. Materials and Methods
Utilizing a mixed-methods approach that draws on a wide range of literature streams, this paper aims to construct an integrative framework that effectively identifies key elements and design choices in platform businesses to foster sustainability outcomes. The research amalgamates essential concepts from platform literature, business models, and sustainable innovation, incorporating morphological analysis as a powerful tool to discern the crucial components and design alternatives in platform businesses, particularly concerning sustainability.
Following the three dimensions of business model design, as conceptualized by Teece (2010), this study systematically categorizes the extracted elements into three distinct areas: i) value creation, ii) value delivery, and iii) value capture. This chosen approach allows for a comprehensive qualitative analysis of multidimensional objects while offering the added advantage of reducing complexity, thereby accommodating diverse combinations of attributes [
15]. Employing the MAXQDA software, the individual design choices identified are meticulously assigned to their respective business model dimensions.
In order to validate and exemplify the proposed framework, the study extensively analyzes the business models of 50 identified platforms against the identified elements, utilizing qualitative content analysis as the primary methodological tool. To ensure relevance and appropriateness, a set of stringent criteria is applied, leading to the selection of 20 cases that meet the following criteria: 1) digital platforms, 2) possessing a sustainable value proposition, and 3) currently operational.
The ultimate objective of this research is to unveil specific design choices for platform architecture that have the potential to optimize their business models in favor of sustainability.
2.1. Theoretical framework
This section discusses and summarizes the most important features of digital platforms and business models for sustainability (BMfS) to prepare the foundation for the morphological analysis.
2.1.1. Digital platform organizations – a socio-technical construct
Digital platforms hold a predominant place in today’s economy. The combined market capitalization of the top four platforms by market capitalization, Apple, Amazon, Microsoft and Alphabet/Google was US$5,7 trillion in 2023, exceeding Germany’s GDP. These four companies, and digital platforms in general, share an underlying business model which leverages digital technologies to facilitate matchmaking and innovation. Scholars from both information systems and management have studied this phenomenon from diverging perspectives.
While on the one hand management and economics literature looks at platforms from a market-based perspective, where their ability to mediate complex transactions between two or more groups of agents [
6,
7,
16], and creating value by leveraging network effects [
17] are key.
On the other hand, information systems literature studies platforms from a technical perspective. Scholars in this field have focused on the layered architecture and modularity that distinguishes digital platforms. They define them as a set of stable components that provides functionalities in a system by constraining the interfaces through which they operate [
8,
18]. The interfaces dictate the degree of openness and control which creates value for the platform sides in terms of innovative outcomes.
Furthermore, a socio-technical perspective of digital platforms is being increasingly adopted from scholars on both ends [
19] taking a more unified view that incorporates elements from both economics and information systems. Here, platforms are market intermediaries between two or more sides and digital, modularly-architectured entities.
By adopting the socio-technical view, this paper sees platforms as an IT artefact which exists within a network of stakeholders that interact in complex ways, and whose existence and evolution is influenced by a broader set of external forces with implications for its long-term sustainability [
20]. As such, platforms rarely exist in isolation and are part of an ecosystem which contributes to its functioning [
6].
2.2.2. Platform and their ecosystems as a collaboration environment for sustainability
The platform ecosystem is referred to in the literature as a set of interdependent and interconnected components, including firms, developers, users, and other stakeholders, that interact with each other and with the platform owner to create value [
21]. Inherent to digital platforms, and as a result to platform ecosystems, are network effects where the value of the platform increases as more users join and more complementary products and services are offered [
17]. The ecosystem can also be affected by platform governance, which includes policies, rules and interfaces that determine how the platform and its participants interact.
Platform ecosystems play a critical role in promoting sustainable development by facilitating collaboration and increasing the pace of innovation which would otherwise not be possible [
20]. There is a growing body of literature which links platform ecosystems, viewing them as a multi-stakeholder collaboration framework for sustainability [
22], as interactions between stakeholders to facilitate collective efforts towards increased societal impact [
23,
24] and from a socio-technical perspective where the ecosystem is composed of interdependent technical, social, political and spatial components [
20] which together have an impact on sustainable development.
In their work, Hellemans et. al (2020) highlight the role of digital platforms for sustainability as they facilitate joint action by lowering the barriers to access and reach [
25] by means of technology. The increasing ubiquity as well as decreasing cost of digital technologies has enabled previously unconnected people and organizations in distant places to exchange and share information [
20]
For instance, eKutir in India is a digital platform joining farmers, retailers and consumers to share information and resources to tackle food waste [
26]. The ecosystem that results from the platform players and interactions has the potential to facilitate collective efforts towards increased societal and environmental impact [
23].
However, digital platform firms can generate unwanted outcomes and paradoxical effects [
20,
27], such as citizen surveillance, questionable work practices, increased pollution and the rise of monopolistic powers [
28]. Understanding how digital platforms can be designed to encourage positive outcomes and minimize their paradoxical effects is still unresolved [
23]
2.1.3. Business models for sustainability (BMfS)
Scholars from economics and management have increasingly put their attention into business models due to their importance in determining the fundamental logic of a company [
29]. With the term first appearing in the twentieth century in management theory [
30], it has expanded to business informatics and strategy theories and has become an integrated management concept [
31]. In practice, a successful implementation of a business model signifies the success of a business. It describes a firm’s logic of creating, delivering and capturing value [
30]
In this view, social and environmental value is seen as subordinate to economic value [
12], and organizations are seen as purely economic entities. However, sustainability scholars have increasingly adopted business models as a unit of analysis and are looking to understand the triple bottom line value creation [
32]. This phenomenon has been studied under the labels of sustainable business models (SBMs) and business models for sustainability (BMfS) and, in essence, extend the purely economic view of business models including the natural environment and society [
33].
Schaltegger et. al (2016) provide a definition of BMfS where “A business model for sustainability helps describing, analyzing, managing, and communicating (i) a company’s sustainable value proposition to its customers, and all other stakeholders, (ii) how it creates and delivers this value, (iii) and how it captures economic value while maintaining or regenerating natural, social, and economic capital beyond its organizational boundaries”. This view integrates the most prominent literature on sustainable business models [
12,
14,
34] taking both the creation of customer and social value and the integration of social, environmental, and business activities into the definition.
Furthermore, attempts to conceptualize BMfS are relatively scarce. Scholars in this field have researched the potential of BMfS in different industries and use cases (Kien & Raharso, 2017; Rosen 2017)[
20], network and stakeholder ecosystem [
35], and the different typologies [
36,
37,
38] which greatly contribute to better understanding business models for sustainability.
This paper defines digital platforms for sustainability (DPfS) as a socio-technical construct where:
“DPfS are an i) IT artefact which exists within a network of stakeholders that interact in complex ways, and ii) creates, delivers and captures economic value while maintaining or regenerating natural, social and economic capital beyond its organizational boundaries”.
4. Discussion
The role of current and future entrepreneurs in promoting sustainable development is significant. A paradigm shift towards fostering value not solely for financial objectives but also for social and ecological purposes challenges the conventional notion of business, where ethical considerations and profitability may not necessarily align. For digital platforms, this transformation entails harnessing their network effects and market influence to create economic value while simultaneously preserving or regenerating natural, social, and economic capital beyond their organizational boundaries.
In view of the winner-take-all nature intrinsic to platform businesses, their profound impact on society entails a corresponding importance to act responsibly and equitably. Presently, numerous instances underscore the need for platforms to be held accountable for their actions, as they face scrutiny for imprudent practices and unintended negative consequences. Such instances may encompass social networks propagating misinformation and polarization, food delivery platforms with negative employment practices, and short-term rental platforms exacerbating gentrification in urban centres.
This research contributes to the existing literature on sustainability and platforms by introducing a morphological box, which serves as a valuable instrument for platform practitioners to identify, validate, and implement sustainable practices within their platform architecture. Adopting an integrated perspective that combines sustainability and platform theory, this study reveals specific design choices for platform architecture that empower platform practitioners to optimize their business models for sustainability. The ensuing paragraphs expound upon the architecture of the principal business model dimensions and the fundamental design parameters that characterize digital platforms for sustainability (DPfS).
First, digital platform businesses create value through the deliberate design of architecture and mechanisms that regulate interactions between different sides of the platform, as well as orchestrate resources and processes. The process of building a platform requires careful consideration of its type, governance, and capabilities to ensure its effective and sustainable operation over time. In this regard, mechanisms like cooperative ownership and public-private partnerships play a vital role in transcending narrow for-profit and profit-maximizing models, contributing to platform sustainability. However, it is important to note that effective governance remains a critical factor for ensuring the long-term sustainability of a platform.
Interestingly, the research findings indicate that transaction platforms are more prevalent in the sustainable business landscape, not necessarily because they inherently produce more sustainable outcomes, but due to the resource-intensiveness associated with innovation platforms. This insight sheds light on the factors influencing the distribution of platform types in the context of sustainability.
In terms of pricing, we observed that prices for goods and services on platforms are typically determined by the supply side, whether it's for a ride, an egg carton, or a ton of CO2. Notably, we did not find evidence of pricing being set by the demand side or through direct negotiations between parties. However, consumers can ensure fair prices through competition amongst suppliers on the same side of the platform. Additionally, trust mechanisms play a significant role, where consumers can review products or services, or the platform itself assumes the role of a reviewer to ensure quality across the supply side.
Moreover, the value delivery dimension of platforms should extend beyond traditional customers and incorporate a broader range of stakeholders. This requires a comprehensive understanding of the major stakeholder groups, including private sector, social enterprises, NGOs, government, international organizations, bottom of the pyramid consumers, and the natural environment. Platforms rarely exist in isolation and are the foundation for a multi-stakeholder collaboration which facilitates collective efforts towards increased impact. A sustainable platform architecture requires a conscious effort to balance the interests of these various stakeholders while simultaneously promoting social and environmental sustainability.
Technological interfaces, particularly software tools, play a crucial role in facilitating and managing the relationship between the platform owner and its ecosystem, thereby creating value. The level of complexity in these digital interfaces varies based on the platform type, with innovation platforms generally being more technologically intricate compared to transaction platforms. However, both types rely on IT infrastructure and gather valuable data to function effectively as socio-technical constructs.
The openness and accessibility of data and digital interfaces have a significant impact on various aspects, including innovation, transparency, and privacy. Depending on the platform's approach to data sharing and interface availability, these factors can either hinder or foster value delivery within the platform ecosystem. Additionally, the degree of openness can also influence the platform's potential for practicing and promoting sustainability.
Capturing value in multi-sided platforms, particularly those deemed sustainable, presents an added layer of complexity. Platform owners face the challenge of striking a delicate balance in devising an optimal pricing strategy that simultaneously maximizes economic profit, enhances consumer welfare, and promotes ecological well-being. To achieve this delicate balance, platforms employ a range of monetization mechanisms, including subscription models, transaction fees, advertising revenue, differentiated pricing, and performance-based pricing.
The adoption of sustainable business model design patterns further contributes to fostering sustainability. Examples of such patterns include charging different prices to various groups based on their income levels and implementing freemium pricing models, where basic services are provided for free, with additional premium features offered for a fee.
In the context of transaction platforms, our sample data indicates that subscription fees are relatively uncommon. Instead, platform owners predominantly rely on transaction fees charged to consumers. In this role, the platforms function as matchmakers, facilitating transactions between different sides of the platform.
In conclusion, this study highlights the significant role of current and future platform owners in promoting sustainable development, challenging traditional business notions by emphasizing value creation for social and ecological purposes. Digital platforms have the competitive characteristic of creating network effects and market influence to generate economic value while preserving or regenerating natural, social, and economic capital beyond organizational boundaries. However, platform businesses' winner-take-all nature necessitates responsible and equitable actions to address their profound societal impact. The research contributes to the literature through a morphological box that empowers platform practitioners to identify and implement sustainable practices throughout their value creation, capture and delivery chains.
Managerial implications
The resulting morphological box can aid platforms owners to identify sustainable business model elements, review their current businesses and innovate towards platforms that do well and do good and remain competitive.
Platforms should embrace the paradigm shift towards fostering value for social and ecological purposes alongside financial objectives. Aligning ethical considerations with profitability can lead to more sustainable business practices and enhance the overall impact of digital platforms. Employing effective mechanisms such as effective governance, prioritizing sustainable design patterns, engaging multiple stakeholders and leveraging technical interfaces is encouraged.
As platform owners use the proposed framework to design their platforms’ value creation, delivery and capture mechanisms, we expect new business models to arise and platform owners to adjust their business strategy according to the design choices.
Future research and limitations
The digital economy is increasingly being driven by platforms and further research on this phenomenon is relevant both to platform practitioners, policy makers and society at large. While this paper advances research on the implementation of business models for sustainability (BMfS) in the context of digital platforms, the author acknowledges that the research gap can be further developed.
The morphological box was empirically tested with selected cases and a relatively small sample (20). Digital platforms for sustainability are in continuous growth across the globe and entrepreneurs are finding innovative ways to design their business models which may not have been captured within the proposed artefact. Therefore, the author acknowledges the limitations of the empirical approach and encourages researchers to continue the identification of additional elements which could be included.
Furthermore, this research has taken one of the existing business model frameworks [
30] as a guide to classify the dimensions, subdimensions and individual elements of the morphological box, however, there are other ways to structure digital platforms when using a different theoretical lens which can help further the sustainability and digital platform agendas.
Lastly, this work did not focus on specific industries or geographies to build the morphological box. By taking one industry type as a focal point of digital platforms, the design choices which optimize the business model for sustainability may appear clearer and could extend the model into more verticals.
