INTRODUCTION
Globally, financial transactions and payment methods continuously evolve, driving modern economic development (Popelo, Dubyna, & Kholiavko, 2021). While the COVID-19 pandemic impacted national economies and consumer spending, it simultaneously accelerated e-commerce industry advancement (Ilieva et al., 2022). Traditional currencies and paper checks are gradually being replaced by rapidly emerging electronic payments and digital currencies (Lee, Yan, & Wang, 2021). Mobile payment systems now fundamentally transform transactional processes, financial management, and business interactions. Concurrently, new digital lifestyles—including online shopping, payments, and education—are proliferating (Gomber et al., 2018).
According to the China Internet Network Information Center (CNNIC), China had 1.079 billion internet users by June 2023, reflecting an 11.09 million increase since December 2022 with 76.4% penetration. Online payment users reached 943 million (87.5% of internet users), marking a 31.76 million growth. Online payment transaction volumes maintain steady growth, as illustrated in Figure 1 (Data from CNNIC).
Figure 1 Online Payment User Scale and Usage Rate From 2014 to June 2023
The emergence of mobile payment systems marks an extraordinary milestone in financial and technological history (Panetta, Leo, & Dell, 2023). Mobile payment—defined as conducting financial transactions via mobile devices—replaces cash, checks, and physical cards with electronic transfers for purchases, money movement, and bill payments (León, 2021). These systems deliver unmatched convenience and efficiency, enabling instant access to financial services through simple touch interactions. Today, mobile payments have not only become indispensable to daily life but also drive economic growth and technological innovation. Beyond mere transactions, they fundamentally transform fund management, commerce, and interactions with financial institutions (Mützel, 2021).
Mobile payment systems enable users to conduct transactions, transfer funds, and access financial services conveniently through mobile applications, websites, or specialized platforms. These systems are transforming traditional business models and accelerating the transition toward a cashless, interconnected global economy. They have redefined consumer behavior and expectations, establishing new benchmarks for efficiency, security, and convenience.
However, mobile payment adoption introduces significant challenges. Data privacy concerns, cybersecurity risks, and regulatory compliance have emerged as critical discussion points. Furthermore, compared to traditional financial systems, these novel payment mechanisms present distinct legal and regulatory implications requiring thorough examination and resolution.
Consequently, research on mobile payment systems holds high relevance, as it encompasses financial ecosystems, business practices, and societal structures. To map the field’s current landscape and future trajectory, the CiteSpace visualization tool is employed to analyze high-impact literature. Analysis focuses on three dimensions:
- Representative national research contributions
- Keyword co-occurrence patterns
- Co-citation networks of seminal works
This approach reveals the dynamic evolution of mobile payment systems and projects future research directions. Comparative examination of domestic and international scholarship enables a more comprehensive understanding of this rapidly evolving field.
LITERATURE REVIEW
Mapping knowledge domains was a graphical and serialized knowledge spectrum used to display the knowledge evolution process and knowledge structure (Chen, et al., 2015). Garfield (1955) introduced the idea of applying citation indexing for literature retrieval, and he also developed a series of mature conceptual tools to study the dynamic development of science. This greatly changed the way scientometricians studied scientific communities and laid the foundation for basic knowledge graphs. Price (1965) pointed out that the citation network was similar to the “topographic map” of contemporary scientific development and proposed a method of using citation networks to study the development context of contemporary science. Since then, analyzing citation networks has become a common method for studying the development context of science. It should be noted that the famous German scientometrician Kretschmer (1999) made significant contributions to the development of knowledge graphs through his research on a three-dimensional spatial model of scientific collaboration.
Chen (2002) believed that in-depth theoretical and practical research on scientific knowledge graphs would become a central topic in the future. Therefore, the concept of the scientific knowledge graph was proposed in a symposium organized by the National Academy of Sciences in 2003. Since then, with the development of information visualization, a variety of tools for creating scientific knowledge graphs have emerged (Chen et al., 2008). These included the business network analysis software “Ucinet” developed by Borgatti, Everett, and Freeman (2002), the large-scale complex network analysis tool “Pajek” written by Batagelj and Mrvar (2004), the visual knowledge analysis software “Citespace” jointly developed by Professor Chen (2006) and the WISE Laboratory of Dalian University of Technology, the specialized literature measurement freeware “Bibexcel” developed by Persson, Danell, and Wiborg (2009), the edge dynamics software “Gephi” based on the Java Virtual Machine by Bastian, Heymann, and Jacomy (2009), and the literature knowledge unit-specific visualization software “VOSviewer” developed based on VOS visualization technology by VanEck and Waltman (2010).
Among them, CiteSpace knowledge visualization software has suddenly emerged and become one of the most popular knowledge mapping tools. The fundamental principles of CiteSpace are explained in the paper “CiteSpace II: Detecting and Visualizing Emerging Trends and Transient Patterns in Scientific Literature” by Chen (2006). As of October 25, 2023, this paper had been cited 5,747 times on Google Scholar (GS). The Chinese version of the paper, authored by Chen, Hou, and Liang (2009), has also been cited 552 times on GS. Due to the distinctive characteristics of the CiteSpace knowledge graph, CiteSpace has been rapidly and widely used, leading to several literature reviews on the application of CiteSpace and its knowledge graph.
Hou and Hu (2013) were among the early adopters of CiteSpace, using it to analyze the disciplinary distribution and functionality of papers utilizing CiteSpace in both WoS and CNKI. Hu, Sun, and Wu (2013) reviewed the current situation of knowledge graph application in China and stated: “After the introduction of CiteSpace and knowledge graph drawing methods, domestic scholars’ research on this topic has shown a spurt.” Zhao (2012) conducted a survey of the current state of knowledge graph applications in China based on CiteSpace. The study discussed important issues existing in CiteSpace applications from four aspects: search of domain documents, detection of mutation words, time zone segmentation and threshold setting of related parameters, and map interpretation. Since the outbreak of the new crown epidemic, changes have occurred in all aspects. Wan, Dawod, Chanaim, and Ramasamy (2023) conducted scientific measurements using CiteSpace to deeply research literature on IoT-assisted COVID-19 research. This has provided clearer insights into methods to contain the epidemic, bringing many conveniences to people’s lives.
Since May 2012, the Knowledge Graph project released by Google has announced the construction of the next-generation intelligent search engine. This initiative introduced the concept of knowledge graphs in the field of search engines and began to be widely applied. At present, many large-scale general knowledge graphs have been established. In 2012, the Wikimedia Foundation initiated the Wikidata project to make Wikipedia more precise by providing better data. In terms of applications, Google Knowledge Graph and Microsoft search engine Satori are both designed based on multi-data fusion to enhance search engine results and improve search experience. The Institute of Computing Technology at the Chinese Academy of Sciences has developed a prototype system based on the Open Knowledge Network (OpenKN) to build a knowledge graph using Open Knowledge Network data.
Wu, Yang, Lai, and Lin (2016) began with the construction of a knowledge graph and proposed a definition of a knowledge graph based on existing research results: a knowledge graph is a structured semantic knowledge base that describes the physical world in symbolic form, encompassing concepts, and their interrelationships. With the rapid development of the digital age and widespread applications across various industries, although mobile payment systems have made significant progress, this area is still full of potential and challenges. Scientific knowledge graphs hold important research and application value and will be more widely studied and applied. In this study, the advantages of CiteSpace will be leveraged to conduct an in-depth analysis of the literature related to mobile payment systems. This analysis aims to provide a better understanding of the primary developments and trends within this field.
Data Acquisition and Method
Data Collection
The Web of Science Core Collection database contains more than 12,000 of the world’s most authoritative and high-impact academic journals, dating back to 1900. WoSCC is one of the important sources of scientific information (Chen et al., 2012). The research in this study will use the search term “mobile payment” to explore literature published from 2004/01/01 to 2023/12/31. This period (2004-2023) was chosen due to PayPal’s rise to prominence as a significant online payment system in the early 2000s, prompting many researchers to study mobile payment during this time. Search terms include the following: TS (topic search) = “Mobile payment”. The selected language is “English,” and the selected document types are “Article” and “Review Article.” Choose “Plain Text File” for the file format and “Full Record and Cited Reference” for the record content. Ultimately, 1038 documents were obtained as data sources.
Bibliometric Analysis and Tools
CiteSpace is a software package commonly used for bibliometric visual analyses. It can visualize academic references, authors, or journals and create co-occurrence network maps of keywords, authors, countries, and institutions for a specific topic (Chen et al., 2012). In this study, the following CiteSpace parameters were utilized: time slice (2004 to 2023) with a year for each slice set to 1. Depending on the type of analysis performed, different node types were selected. The selection criteria in CiteSpace were as follows: g-index = 25, Top N = 50, Top N% = 10%/100. The thresholding parameters included citation (c), co-citation (cc), and cosine coefficient thresholds (ccv) set at 2/2/20, 4/3/20, and 3/3/20, respectively. Usage 180 = 50, Usage 2013 = 50 were selected, with no citations, pruning selected with Pathfinder, pruning sliced networks, and pruning the merged network. Visualization was selected with Cluster view and show merged network. This study extracted literature data on mobile payment from the WoSCC database and analyzed it from different angles, including keyword cluster analysis, citation burst detection, country and institutional analysis, and subject category analysis.
RESULTS AND DISCUSSION
This study presents the analysis results and discussions of mobile payment research in two stages: (1) Descriptive analysis and retrieval, which includes the distribution of countries/regions, institutions, authors/co-cited authors, and co-cited journals. (2) Conducting an in-depth analysis of the topic, combining bibliometrics and visual analysis to describe the evolution of the topic in this field, and identifying the characteristics and trends of mobile payment research.
Descriptive Analysis
The changes in the number of articles can be visualized to observe the development status and trend of a research field. As shown in Figure 2, the number of Mobile payments published articles, it was shown that there were five articles published from 1999 to 2004. These five articles were published in conference journals, which can be seen as the beginning stage of exploration. Therefore, this study will start in 2004. Since 2004, it can be seen that there has been a gradual increase in the number of studies on Mobile payment. By 2012 the number of articles published this year was more than ten. The rapid development of the Internet has also contributed to the progress of the payment industry. The expanding field of mobile payment research and the deepening of research content indicates that the field has received active attention from various researchers. As of 2023, the number of articles published in the current year has reached 185. From the trend, it can be concluded that mobile payment is multiplying. This growth is expected to continue in the coming years, making it an important field of study. Additionally, with the continuous development of technology, new payment methods will be created, further driving the growth of the payment industry.
Figure 2 The Publication of Mobile Payment from 1999 to 2023
Distribution of Countries/Regions and Institutions in the Mobile Payment
Table 1 and Table 2 displayed the number of publications, total number of papers, and centrality of the top 15 countries/regions (84 in total) and institutions (350 in total) that had published on mobile payment. Figure 3 and Figure 4 illustrated the visualization of the research countries/regions and institutions that had published mobile payment literature in WoSCC. From this data, it was evident that these countries/regions and institutions formed a complex network of relationships, reflecting close cooperation among them. The larger the node, the greater the number of publications in that country, and the width of different colored circles indicate the number of publications per year. The color of the connecting line between the nodes indicates the time when the two nodes first cooperated, and the thicker the connecting line, the deeper the cooperation between the two countries (Chen et al., 2012). Centrality represents the importance of a particular node in the network (Chen et al., 2012). Therefore, the more central a country/region or institution was, the more publications it had from other countries/regions or institutions. After implementing the “Removal-duplication” function in CiteSpace, a total of 1,038 mobile payment research papers were obtained between 2004 and 2023. The visualization of countries conducting mobile payment research was generated with the help of pruning parameters (based on Pathfinder/Pruning sliced networks and Pruning the merged networks).
Figure 3 Countries/regions Cooperation Network Map
After running the software, the network contained 100 nodes and 98 links with a density of 0.0281 (as shown in Figure 1). Table 1 listed the 15 countries/regions with the most mobile payment studies. According to the number of studies, China had the highest number of publications, totaling 325, followed by the United States with 131 and India with 130, followed by Taiwan, China with 84, and Malaysia with 77. Although China had the largest number of articles, it ranked seventh (0.17) in terms of comparative centrality. This indicated that mobile payment in China was at a booming stage. However, another point that could not be ignored was that the number of articles in Chinese was concentrated at the start of 2018, which also indicated that in recent years, China had also conducted more in-depth research and innovation in the field of mobile payment. Furthermore, with development, China’s mobile payment technology and experience had also provided reference and guidance for other countries and regions. This was also evidenced by the citation volume of the articles issued. Shao et al. (2019) had 197 citations, and Cao et al. (2018) had 178 citations. It is worth noting that nodes (countries/regions) with high centrality measures did not necessarily have high “counts” (counts represented the number of publications). This suggested that China was not cooperating extensively with other countries in terms of publications.

Finland, France, and Spain had 22, 21, and 46 articles. It was observed that these three countries did not have a large number of articles, but their centrality was relatively high: Finland (0.73), France (0.57), and Spain (0.45). Finland ranked first in centrality (0.73), with the highest cited article from Finland (433) published in 2007, indicating relatively early engagement in the study, with only three articles on mobile payments in 2007. Mallat (2007) explored consumer attitudes towards mobile payments, offering an in-depth qualitative analysis of the research. Dahlberg’s articles on mobile payments, published in 2008 and 2015, had citations of 382 and 271. Karjaluoto etal., (2019) also contributed to mobile payment research with 152 citations. It was evident that Finland had started its mobile payment research earlier and had a relatively long history in the field.
Table 1 also indicated that Spain (0.45), the UK (0.22), and Australia (0.28) followed in terms of centrality and also had a certain number of publications. Therefore, it could be concluded that Europe has been in a leading position in the field of mobile payment. Furthermore, the articles demonstrated that research and development efforts covered various aspects, including technological innovation, market demand, laws, and regulations. The results of this research were not only applied in Europe but also had an important impact on the global mobile payment industry. Additionally, the distribution of countries revealed that both developed and developing countries were actively conducting big data-related research. Mobile payment research has garnered the attention of countries worldwide, making it a global research hotspot and key issue.

Analysis of Keywords
Keywords are typically the core and essence of an article, serving as a high-level summary and condensation of the article’s topic. Keywords with high frequency are often used to identify hot issues in a research field (Chen et al., 2012), providing a macroscopic reflection of the research hotspots within a certain period. Furthermore, keywords can also be instrumental in identifying potential topics for future research, tracking trends, and determining further research directions. In order to explore the research hotspots, developmental contexts, and future trends of mobile payment, this study conducted keyword co-occurrence analysis, keyword cluster analysis, and keyword burst analysis on literature spanning from 2004 to 2023.
Keyword Co-Occurrence Knowledge Map
This study analyzed the keyword co-occurrence knowledge graph to illustrate the evolution of the mobile payment field (keywords were extracted from 1038 records). The categories studied in mobile payment were determined by pruning parameters (based on Pathfinder/Pruning sliced networks and Pruning the merged networks). The network contained 142 nodes, 179 links, with a density of 0.0179 (as shown in Figure 10). In the keyword co-occurrence knowledge graph, node size represented the frequency of keyword co-occurrence. Changes in node color and connections between nodes represented keywords appearing at different times and the different times for establishing connections between them. The thickness of connections represented the co-occurrence intensity between nodes. As seen from the co-occurrence map in Figure 10, in addition to the keyword search based on mobile payment in this article, nodes such as Information technology, Adoption, and User acceptance followed mobile payment. This indicated that technology, innovation, and acceptance were research trends in the field of mobile payment. Additionally, the closely connected nodes and connections in the figure showed that research on mobile payment was establishing a closely connected network. This co-occurrence network diagram provided a comprehensive and clear perspective on the research topic in the field of mobile payment.
Figure 10 Keywords Co-Occurrence Network Map
Keywords with high centrality and frequency represented issues of common concern to researchers within a period, signifying research hotspots. The importance of a node’s position in the network reflected its significance in the field. The higher the co-occurrence frequency of keywords and the higher the centrality, the more important the node was in the field (Chen, 2017). However, high frequency did not necessarily equate to high centrality, and vice versa. The keyword co-occurrence frequency table was shown in Table 8. Excluding “mobile payment,” it was observed from the table that “adoption” ranked first in both centrality (0.52) and frequency (271). “Information Technology” followed with centrality (0.42) and frequency (223), while “User Acceptance” held centrality (0.24) and frequency (210). It was evident that the primary keywords studied in mobile payment included “Adoption,” “Technology,” and “Acceptance.” Additionally, other prominent keywords comprised “model” (0.15), “services” (0.12), “intention” (0.1), “trust” (0.05), and “Perceived risk” (0.03). Indeed, these terms collectively highlighted key areas of concern in the field, providing valuable insights into the complexities and challenges associated with mobile payment systems.

Based on the keywords in Table 9 and the Timeline Map in Figure 11, it can be observed that there were four research stages in the field of mobile payment. Early exploration stage (2004-2008): During this period, mobile payment was primarily in its initial exploration phase, with research focusing on technical feasibility, consumer acceptance, and the establishment of payment systems (Chen, 2008; Mallat, 2007). Development and popularization stage (2009-2013): With the gradual maturation and increasing popularity of mobile payment technology, research shifted towards the practical application of mobile payment systems, consumer adoption behavior, and the expansion of payment services (Schierz etal., 2010; Kim et al., 2010). Rapid growth stage (2014-2018): During this phase, mobile payment rapidly evolved into one of the mainstream payment methods, leading research to concentrate on the security, user experience, and business model of mobile payment systems (Olivera et al., 2016; Qasim &Abu-Shanab, 2016). Maturity and optimization stage (2019-2023): As the mobile payment market continued to mature and competition intensified, research began to focus on optimizing the mobile payment system, enhancing user satisfaction, and constructing and standardizing the mobile payment ecosystem (Chang & Ferreira, 2019; Sufyan & Mas, 2022).
CONCLUSIONS
This study finds that the current research landscape in mobile payment primarily encompasses user experience and adoption research. Researchers delve into users’ engagement with mobile payment applications, examining their acceptance of mobile payment, usage motivations, and perceptions of security and convenience (Kim et al., 2010; Wong et al., 2020). As mobile payment gains widespread adoption, security and privacy protection have emerged as central research themes. Scholars investigate secure payment technologies, user privacy safeguards, and users’ trust in mobile payment security (Yang et al., 2015; Liebana et al., 2020).
Regarding business models and ecosystems, research focuses on collaborative dynamics and profit allocation among ecosystem stakeholders, alongside business model innovation and competitive interactions between different payment frameworks (Liebana et al., 2014; Patil et al., 2020). Additionally, mobile payment’s cross-disciplinary nature has spurred growing interest in interdisciplinary research, where scholars analyze influencing factors and developmental trends from multifaceted perspectives (Oliverira, 2016; Ooi, 2016). The integration of emerging technologies such as blockchain and artificial intelligence has also become a prominent research focus, with studies exploring their application potentials in mobile payment and their impacts on transaction security and efficiency (Pal et al., 2020; Faridi & Siddiqui, 2020).
The key research focuses and emerging trends in mobile payment prominently include intelligent payment solutions. As artificial intelligence technology advances, intelligent payment has emerged as a core research domain, encompassing areas such as user behavior analysis via big data, machine learning-driven intelligent risk control, and automated transaction optimization (Dhanasekaran & Kasi, 2019; Teng & Khong, 2021). Globalization has also shaped research on cross-border payment systems, addressing technical standardization, regulatory harmonization, and payment settlement mechanisms across jurisdictions (Zetzsche et al., 2021; Bindseil & Pantelopoulos, 2022). Meanwhile, studies on the socioeconomic impacts of mobile payment have gained traction, examining its effects on financial inclusion, shifts in consumption patterns, and business model innovation (Siano et al., 2020; Pal et al., 2020, 2021).
The rise of blockchain technology and digital currencies has introduced new dimensions to mobile payment research. Researchers focus on blockchain’s applications in secure transaction verification, decentralized finance (DeFi) integration, and the developmental trajectory of central bank digital currencies (CBDCs) (Zhang & Huang, 2022; Islam et al., 2022). Additionally, payment standards and regulatory frameworks hold significant importance in the field. Scholarly attention centers on the formulation and global harmonization of payment protocols, as well as the adaptive adjustment of regulatory policies to balance innovation and risk management (Ahmed et al., 2021; Brunnermeier & Landau, 2023).
This study offers empirical insights through CiteSpace-based visual analysis of the current landscape and emerging trends in mobile payment research. The findings reveal that new key research themes and developmental trajectories continue to emerge in the field of mobile payment. Researchers are expected to deepen their exploration of critical areas such as mobile payment technologies, business model innovation, and security mechanisms, thereby driving further development and innovation in the mobile payment domain.
Limitations and Suggestions
In terms of keyword selection, various keywords have been used in research on mobile payments, such as “mobile payment,” “electronic payment,” “digital payment,” and “online payment.” However, in this study, only “mobile payment” was selected as the keyword. This selection limits the breadth and comprehensiveness of the research, potentially resulting in the omission of other relevant studies in the field. Therefore, future research should consider using a wider range of keywords to enhance comprehensive understanding of the field.
Regarding database selection, this study used only Web of Science as the data source. Although Web of Science is an important and authoritative academic database, relying solely on a single database may lead to the omission of certain research. Therefore, future research should consider integrating multiple databases (e.g., Scopus, Google Scholar, IEEE Xplore) to ensure data comprehensiveness and diversity, thereby improving the accuracy and reliability of results.
By expanding keyword scope and database usage, future research will be able to more comprehensively cover the latest developments and trends in mobile payments, providing more comprehensive reference materials for academic research and practical applications.
