Theoretical Lens: DCT

The theoretical perspective used to understand the development of the fintech-sustainable development literature is Dynamic Capabilities Theory (DCT). DCT is used to interpret the development of fintech-sustainable development literature. According to Teece et al. (1997), dynamic capabilities are organisational processes that help companies adapt and reconfigure resources in the face of technological and market shifts. Teece (2007) then comes up with three sets of interrelated skills: sensing, seizing, and reconfiguring, which describe how organisations discover opportunities and marshal resources around them, and how they convert resources and processes. This view is especially relevant to the fintech industry, given the swift pace of technological advancements and the necessity for organisations to adapt as necessary.

For the purposes of this review, fintech may be defined as a technological capability that can be applied and reconfigured in various ways by organisations and the financial ecosystem, thus implying sustainability consequences. The sensing dimension is about recognising emerging sustainability needs and opportunities, including the gaps in the financial markets, climate finance needs, ESG information needs, and emerging digital financial needs. The seizing dimension relates to the creation and availability of digital payments, digital lending, green-finance platforms, sustainable investment mechanisms, AI-based analytics, blockchain applications and other fintech solutions that will meet the above opportunities. The reconfiguring dimension reflects changes in organisational processes, the allocation of resources, stakeholder relationships, governance mechanisms and business strategies that can help fintech deliver lasting economic, social and environmental value.

This theoretical interpretation also serves as a link between the bibliometric results and the organisational themes that were found in the review. Financial inclusion can be seen as an opportunity for sustainability that fintech can sense and seize, green finance as the mobilisation of financial and technological resources for sustainability; and enterprise transformation, innovation, governance and stakeholder engagement as possible reconfiguration outcomes. In fact, the literature leaves the adoption of fintech behind to shift to questions of transformation of the organisation and the related sustainability performance, which DCT explains. The framework does not suggest that sustainable development outcomes are necessarily generated by fintech. Instead, the results are highly dependent on organisational capacities, the institutional context, governance arrangements and on technology actors’ ability to combine technological innovation with sustainability goals.

Descriptive Statistics of Publications

Between 2017 and 2024, the academic community produced 256 publications in this field across 97 journals and other publication sources. A total of 736 authors contributed to these publications, demonstrating the collaborative nature of the field, with far more works written by multiple authors (711) than by single authors (25). The average number of citations per document was 11.32, suggesting that the research has made a good academic impact. Additionally, 13.28% of the publications involved researchers from different countries, indicating a good level of international collaboration.

The 1,234 Keywords Plus (ID) and 764 Author’s Keywords (DE) demonstrate the rich and diverse nature of research in this field. On average, each author contributed to 0.34 documents, with an average of 2.875 authors (3.44 co-authors) per document, reflecting the highly collaborative nature of contemporary research. Overall, the review period has been quite productive in terms of research activity and academic collaboration (Table 1).

Annual Publication and Citation Trends

Publications related to fintech and sustainable development have increased substantially between 2017 and 2024. Both 2017 and 2018 recorded only one publication each, whereas 2024 recorded 132 publications, reflecting the rapid growth of the field. The average total citations (TC) per article peaked at 66.00 in 2017 and gradually declined to 1.77 in 2024.

A notable increase in publication output began in 2021, with 22 publications, and further increased to 56 publications in 2023. Although the number of publications has grown significantly over time, the average citations per article have declined (Table 2). This pattern is expected in bibliometric studies because recently published articles have had less time to accumulate citations. Therefore, the lower citation counts of recent publications should not be interpreted as lower research quality but rather as a citation time-lag effect (Figure 2).

The co-occurrence network map illustrates the relationships between important concepts or keywords that appear together in the literature on fintech and sustainability. In this visualisation, the nodes represent concepts, while the edges (lines) connecting them represent the frequency with which these concepts occur together in the literature. The size of the nodes and the thickness of the edges generally indicate the importance or strength of these relationships, helping to identify the major research themes and the integration of different research areas (Figure 10).

Figure 10. Co-occurrence Network Map.

The largest node represents ‘fintech’, indicating that it is the central concept within the network. This suggests that fintech serves as the foundation of the research field, linking several related concepts. Its prominence demonstrates the importance of fintech across multiple research domains, including financial technologies, environmental sustainability, and innovative financial practices.

The network also shows several important thematic clusters surrounding fintech. One sustainability-oriented cluster includes ‘natural resources’, ‘climate change’, and ‘energy efficiency’. These keywords represent the environmental dimension of sustainable development and indicate that innovative financial technologies are increasingly being explored as solutions for environmental challenges, sustainable resource management, and climate change mitigation.

Another major cluster revolves around ‘financial technologies’, incorporating concepts such as ‘artificial intelligence’, ‘blockchain technology’, and ‘sustainable finance’. This cluster reflects the technological dimension of fintech research. It demonstrates how emerging technologies are being integrated to improve the efficiency, transparency, and sustainability of financial systems. Blockchain technology contributes to transparency and accountability, while AI supports prediction, analysis, and financial decision-making for sustainable development.

The network also illustrates the relationship between fintech and concepts such as corporate social responsibility (CSR) and environmental quality. This reflects increasing research interest in the ethical and governance aspects of fintech and how these technologies can support sustainable business practices. The close relationship between fintech and CSR indicates growing attention to improving corporate governance while reducing environmental and social impacts through technological innovation.

The network further highlights the connections between the banking sector, commercial banks, innovation, financial inclusion, and economic growth. Much of the existing research focuses on how fintech promotes access to financial services, particularly in developing countries, encourages entrepreneurship, and improves financial inclusion for economically and socially disadvantaged populations. The concept of innovation occupies a central role within these relationships, reflecting the transformative potential of fintech in modern financial systems.

Thematic Map and Research Clusters

The thematic map classifies research themes according to their levels of development and relevance (Figure 11). The themes are grouped into four quadrants: Motor Themes (high density and high centrality), Niche Themes (high density and low centrality), Basic Themes (high centrality and low density), and Emerging or Declining Themes (low density and low centrality).

Figure 11. Thematic Map.

The Motor Themes include ‘fintech’, ‘natural resources’, and ‘green finance’, indicating that these topics are both highly developed and highly relevant within the field. In contrast, ‘blockchain’ and ‘COVID-19’ appear in the Emerging or Declining Themes quadrant, suggesting that these areas are still developing or remain relatively peripheral. The thematic map also indicates that ‘digital finance’ and ‘banking’ are highly relevant but comparatively less developed, suggesting promising opportunities for future research.

The three-field diagram illustrates the relationships among authors (AU), keywords (DE), and sources (SO) within fintech and sustainable development research (Figure 12). On the left, authors such as Li Y., Wang C., Zhang Y., and others are shown as active contributors to the field. The connections between the authors and the keywords illustrate the research topics they have investigated, including ‘fintech’, ‘sustainable development’, ‘green finance’, and ‘environmental sustainability’.

Figure 12. Three-field Path.

The diagram indicates that authors such as Li Y. and Wang C. have the strongest links with ‘fintech’ and ‘green finance’, suggesting that these are their primary research interests. Other keywords such as ‘financial inclusion’, ‘SDGs’, and ‘renewable energy’ further demonstrate the growing integration of sustainability within fintech research.

On the right side, the keywords are connected to the journals in which the studies were published. For example, ‘green finance’ is strongly associated with the journal Sustainability, while Resources Policy is more closely connected with ‘natural resources’ and ‘sustainable development’. Other important publication outlets include Environmental Science and Pollution Research and the Journal of Risk and Financial Management, highlighting the interdisciplinary nature of fintech and sustainability research.

Conceptual Clustering (Dendrogram Analysis)

The dendrogram illustrates the conceptual clustering of keywords within fintech and sustainability research (Figure 13). The clustering reveals several distinct but interconnected research themes.

Figure 13. Dendrogram Analysis.

One major cluster consists of sustainability-related keywords such as ‘Sustainable Development Goals’, ‘environmental’, ‘green finance’, and ‘social responsibility’. These closely related concepts demonstrate the strong relationship between fintech and environmental as well as social sustainability. Among these keywords, ‘green finance’ emerges as one of the most central concepts because of its close association with environmental sustainability and CSR.

A second major cluster focuses on the technological aspects of fintech, including ‘blockchain’, ‘cryptocurrency’, ‘digital transformation’, and ‘artificial intelligence’. These keywords represent the technological innovations driving modern financial systems. The close relationship between blockchain and cryptocurrency reflects their integrated role within digital finance. The analysis also shows that ‘corporate governance’ and ‘green bonds’ serve as important connecting concepts between fintech and sustainability. Corporate governance links technological innovation with responsible business practices, while green bonds connect financial innovation with environmental sustainability. Similarly, ESG (Environmental, Social and Governance) and impact investing bridge sustainable finance with responsible investment practices.

Author Collaboration Networks

The diagram illustrates the author collaboration network concerning fintech and sustainability (Figure 14). It reveals the complexity of collaboration partnerships among researchers who have worked together or conducted joint research. The central nodes in the network, ‘Nassani A’ and ‘Chen Z’, are larger than the others, indicating that they are key contributors to the field. The size of their nodes reflects their impactful research contributions and extensive collaborative partnerships. Within this research area, their prominence suggests that they play significant roles as emerging leaders and influential contributors in fintech and sustainability research.

Figure 14. Author Collaboration Network.

The network displays multiple clusters representing concentrated research groups or sub-disciplines. For example, the collaboration between ‘Ij J’ and ‘Muda I’ suggests that they belong to a similar research cluster focusing on dominant themes within fintech and sustainability. These clusters reflect academic collaboration networks where researchers with similar interests work closely together, allowing greater knowledge sharing and research synergy. Such clusters also indicate the specialised nature of research interests within the field.

Several authors, such as ‘Chen Z’ and ‘Alromaihi A’, serve as bridge or connector authors between different clusters. These researchers play a critical role by facilitating collaboration across research groups and connecting different sub-disciplines. Their presence promotes the exchange of ideas and supports the integration of diverse research themes. Without these bridging authors, the collaboration network would become more fragmented, limiting the integration of knowledge across fintech and sustainability research.

Authors located on the periphery of the collaboration network have opportunities to increase their research visibility by collaborating with more central researchers such as ‘Nassani A’ or ‘Chen Z’. Such collaborations can significantly enhance academic development by expanding research influence, increasing access to resources, and improving recognition within the scholarly community. Establishing new collaborations between currently isolated research clusters may also create new research directions, encourage interdisciplinary studies, and generate innovative perspectives by combining complementary areas of expertise.

Overall, the collaboration network demonstrates that authors play an important role in shaping the future direction of fintech and sustainability research. Collaboration, particularly across disciplines and geographical regions, strengthens knowledge integration, promotes innovation, and advances the development of the field.

Institutional Collaboration Networks

The institutional collaboration network illustrates the connections among universities and research institutions involved in fintech and sustainability research through joint publications and collaborative projects (Figure 15). King Saud University stands out because of its larger node size and extensive connections with other institutions, including Tashkent State University of Economics. The size of its node indicates its leading position in international collaboration and advanced research related to fintech and sustainability. Its central position reflects its significant contribution to promoting international research partnerships and innovation through collaborative research activities.

Figure 15. Institutional Collaboration Network.

The network diagram also illustrates several regional collaboration clusters. King Saud University serves as an important connecting institution among universities in the Middle East and Asia. These regional clusters indicate strong collaborative research networks that have developed due to shared research interests, geographical proximity, and cultural or linguistic similarities. Such collaborations allow institutions to collectively address common research challenges and strengthen regional research capacity. At the same time, institutions such as King Saud University help connect these regional groups with researchers from other parts of the world.

Cross-border collaborations are also evident within the network. Institutions such as Ibn Khaldun University collaborate with King Saud University and several universities across Europe and Asia. These international partnerships create opportunities for exchanging knowledge, expertise, and innovative ideas related to fintech and sustainability. The presence of such global collaborations highlights the international nature of research in this field and supports the development of diverse and inclusive research partnerships.

The network also identifies opportunities for institutions with relatively fewer collaborations. Such institutions could strengthen their research capacity by establishing partnerships with highly connected universities such as King Saud University. Increased collaboration would improve access to research expertise, technology, funding opportunities, and international academic networks, thereby enhancing the overall quality and global impact of their research.

Country-level Collaboration

The country collaboration network provides a macro-level view of global research partnerships in fintech and sustainability by illustrating co-authorship and international collaboration patterns (Figure 16). At the centre of the network, China occupies the largest node, demonstrating its extensive research output and broad international collaboration with major research countries such as the United States, Saudi Arabia, and Malaysia. China’s central position reflects both the volume of its research and its important role in facilitating global knowledge exchange and collaborative research. It also indicates that China serves as one of the major driving forces in advancing fintech and sustainability research worldwide.

Figure 16. Country Collaboration Network.

The network also highlights the important roles of countries such as the United States, United Kingdom, and Saudi Arabia, all of which serve as major contributors to the global research network. The United States acts as a central hub for collaboration across North America, while Saudi Arabia plays a significant role in connecting research activities across the Middle East with the global research community. These countries facilitate both regional and international collaborations, contributing to the advancement of fintech and sustainability research.

Countries such as India, Indonesia, and Vietnam are emerging contributors within the collaboration network. Although their collaborative networks are not yet as extensive as those of China or the United States, their growing participation demonstrates increasing research interest in fintech and sustainability. Continued international collaboration will strengthen their research capabilities and contribute valuable regional perspectives to the global research community.

Theoretical Interpretation Through DCT

The transition can be explained with the help of DCT. The theory suggests that in ‘fast-changing environments’ organisations must have sensing capabilities to detect opportunities and threats, mobilising resources to exploit opportunities, and restructuring assets and processes to continue adapting (Teece, 2007; Teece et al., 1997). This logic is supported by the present bibliometric data. In recent years, fintech research has shifted its focus from technology adoption to the conversion of technological resources into innovative financial and sustainability capabilities: AI, blockchain, big-data analytics, green finance, ESG and digital financial ecosystems are becoming more and more prominent.

The review thus views fintech as an enabling capability and a value that has to be sustained, which in turn is facilitated by organisational and institutional processes. Sensing is the process of identifying unmet financial needs, climate finance opportunities, ESG information demands and new types of digital demand. Seizing is the process of introducing digital financial products and technologies to bring about a financial mobility of capital, financial extension, decision-making, and sustainable investments. The reconfiguration process includes reconfiguring organisational processes, stakeholder relations, governance, resource allocation and strategy, such that fintech becomes part and parcel of sustainability-oriented processes. The choice of the non-causal interpretation is intentional: the bibliometric study aims at finding patterns and relationships in the literature, whereas DCT aims at providing a theoretical account, a theory to interpret the patterns.

Fintech and Firm Behaviour

The citations to the literature in the dataset are evidence enough that the nexus of fintech and sustainability is becoming more granular and is now at the firm level. The studies on fintech adoption and the transformation of businesses suggest that fintech can have an impact on how firms can access finance, how they allocate resources, how they manage information and how they innovate and adapt to market conditions. Digital financial skills can thus influence behaviour, for example, in terms of managerial attention, investment decisions, risk assessment, and project selection for sustainable development. A dynamic capabilities view suggests that businesses with the ability to identify the opportunities for sustainability and translate those opportunities into sustainable activities via digital finance may have the best chance of being able to re-align resources to the new business models.

Fintech and Stakeholder Relationships

There are also shifts in stakeholder relationships highlighted by the bibliometric themes of financial inclusion, digital ecosystems, SMEs, and sustainable investment. Fintech has the potential to overcome geographical and informational constraints that limit the reach of financial services between financial institutions, customers, companies, investors, governments and underserved communities. Digital financial inclusion can expand access to financial services and systems through mobile banking, digital payments, digital lending and crowdfunding, and digital investment and ESG platforms can make sustainability-related information more visible. The developments indicate that further studies should not be only about the impact of fintech on access to finance but also on the redistribution of information, the impact on the involvement of actors and the impact on trust and accountability.

Fintech, Governance and Accountability

Governance becomes an important linkage between fintech and sustainable development. Some corporate governance, CSR, ESG, transparency and blockchain are considered significant bridging concepts in the keyword and conceptual analyses. AI and big-data analytics can enable monitoring and risk assessment, and blockchain can reinforce the traceability of transactions. But technology transparency is not a one-to-one guarantee of good governance. Issues surrounding data quality, privacy, cybersecurity, algorithmic bias, regulatory coordination, and accountability are still relevant. Therefore, the review recommends that governance arrangements should be in place to transform technology transparency into trustworthy accountability and responsible decision-making, in order to safeguard the future of fintech-enabled sustainability.

Fintech, Innovation and Sustainable Finance

The thematic analyses and co-occurrence show that the concepts of fintech, green finance, innovation, natural resources, renewable energy and sustainable development are closely related. This means that innovation is not only a product of technology, but also a process which can free up financial resources for activities that support sustainability. Fintech solutions like digital green-finance platforms, AI-driven assessment, blockchain-based verification, and more can enhance the efficiency and transparency of sustainable finance. The literature thus suggests that, going beyond traditional financial innovation, a transition towards sustainability-focused financial innovation is underway, where technological design, financial products, and environmental and social goals are becoming more and more intertwined.

Fintech and Firm Strategy

The results also indicate that fintech is gaining momentum as a strategy for companies rather than as a technology. Within the literature, the inclusion of themes such as enterprise transformation, sustainable business models, competitive advantage, innovation and digital ecosystems suggests that fintech can impact strategic decision-making regarding markets, resource allocation, partnerships and business-model configuration. This movement can be understood with the help of DCT: strategic value comes from the ability to adapt capabilities continuously in the face of technological and sustainability challenges. In future, it is therefore necessary to investigate whether there is a relationship between fintech capability and strategy oriented to sustainability, and under which organisational and institutional conditions this is the case.

Policy Implications

Fintech services and technologies provide new opportunities for policymakers to develop governance and regulatory frameworks that promote sustainable development while ensuring responsible financial innovation. These technologies enable faster responses to customer needs by improving financial accessibility, supporting income generation, and promoting greater social and economic inclusion. In turn, they contribute to building a more balanced and sustainable financial ecosystem.

Policies supporting fintech innovation should be designed alongside broader sustainable development strategies. This integration is essential because fintech has the potential to promote financial inclusion, improve public financial management, and strengthen sustainable economic growth. Policymakers who align fintech innovations with global sustainability initiatives, such as the SDGs, can accelerate financial innovation while ensuring that technological advancement contributes to long-term social and environmental sustainability.

Industry Implications

The financial sector is well positioned to benefit from the growing integration of sustainable finance and fintech innovations. This convergence creates significant opportunities for responsible finance, business development, and sustainable investment. Fintech technologies enable investors to channel funds toward renewable energy projects, green initiatives, and environmentally and socially responsible investments. Through improved transparency and greater accessibility, digital financial technologies expand sustainable investment opportunities to a broader range of investors.

Beyond investment opportunities, fintech also provides affordable digital financial services to underserved populations, particularly SMEs and rural communities. Digital lending, peer-to-peer lending, and crowdfunding offer alternative financing options that are often more accessible than traditional banking services. These innovations strengthen entrepreneurship and improve collaboration between rural and urban business communities.

Digital financial technologies also facilitate economic development in underserved regions. Mobile banking, digital payments, and microfinance help integrate rural populations into the formal financial system by providing access to savings, credit, insurance, and other financial services. As a result, fintech promotes economic inclusion by supporting entrepreneurs, farmers, and small businesses.

Furthermore, many fintech firms are increasingly incorporating ESG principles into their financial products and services. By embedding sustainability metrics into investment and financing decisions, fintech companies can promote responsible business practices while providing customers with sustainable investment opportunities.

Academic Implications

Academically, the study contributes by moving the fintech-sustainable development discussion from a descriptive mapping of publications towards a theory-informed interpretation of the field. DCT provides a coherent lens for explaining how fintech-related technological change may be translated into sustainability-oriented organisational and ecosystem transformation. The findings suggest that future scholarship should examine not only which fintech technologies are adopted, but also the capabilities through which organisations sense sustainability opportunities, seize them through digital financial innovation, and reconfigure processes, relationships, governance, and strategy.

The results also support greater integration across finance, strategic management, information systems, sustainability, entrepreneurship, environmental studies, and public policy. In particular, research should examine the boundary conditions under which fintech creates inclusive and sustainable outcomes, including institutional quality, digital infrastructure, regulatory environments, organisational capabilities, data governance, and stakeholder trust. Such work would strengthen the theoretical development of the field by connecting fintech adoption with organisational transformation and measurable sustainability outcomes.
