3.3.1. Keyword Co-Occurrence Analysis
Co-occurrence analysis of keywords can reveal the popular research topics and general research trends in a particular field over the years [
31]. The larger the node, the higher the frequency of occurrence of the keyword, which reflects the stronger research enthusiasm of scholars in the relevant field. The more connections between nodes, the stronger the co-occurrence relationship among them [
49]. By importing the literature into CiteSpace with a time range from 2008 to 2023, employing a “1-year” time slice and selecting “keyword” as the node type, along with selecting the Pathfinder and Pruning sliced networks and Pruning the merged network trimming method, a keyword co-occurrence network was constructed, consisting of 352 nodes and 738 edges. The network density was calculated to be 0.0119, indicating a relatively dense and interconnected structure of research themes.
Figure 5, dentered around enterprise social media, expands into several important key themes, including social media, communication, work performance, knowledge sharing, and more. The dense and intertwined connections among the nodes illustrate the strong association between research topics in the literature. Among them, keywords such as social media, behavior, influence, and performance exhibit larger node sizes, indicating a greater emphasis from researchers on the impact of enterprise social media, as well as aspects related to organizational management and performance.
Summary of high-frequency keywords and centrality statistics (
Table 5) based on keyword co-occurrence graph. From the analysis of keyword frequencies in the field of enterprise social media research, we determined that the term “enterprise social media” has appeared 133 times, significantly surpassing other keywords. It holds the largest node and represents the core of the entire research field. Other prominent themes include social media, work, influence, and communication. The advancement of internet technology has provided convenient services to humans in various ways, speeds, and scales. These services enable users to effectively conduct work on online platforms and foster the prosperity of businesses [
50]. Currently, internet technology has evolved from Web 2.0 to Web 3.0, where artificial intelligence facilitates bidirectional connections between humans and the internet [
51]. Technologies such as big data and AI automatically capture user needs and provide high-quality services [
7]. The user base of social media platforms has experienced explosive growth, and users’ reliance on social media has progressively increased. According to a report by the McKinsey Global Institute, it is estimated that by 2030, approximately 70% of businesses will adopt at least one form of AI technology. A report by market intelligence company Tractica suggests that AI may flourish in industries such as consumer goods, automotive, financial services, telecommunications, and retail. By 2025, the global annual revenue of the AI software market is projected to reach USD 126 billion.
Enterprise social media is a critical medium for information exchange and external governance. Leonardi et al. [
23] have mentioned that enterprise social media can serve as a tool for communication among employees and be used in organizational work. As a platform for users to create, disseminate, and acquire information, enterprise social media offers convenience and efficiency in its operation [
52]. Zhao [
53] found that employees can establish faster connections with others and obtain and disseminate information more quickly through social media. In the era of the digital economy, social networks and other media have expanded the spatial scope of information dissemination [
54]. The rise of social media has significantly reduced the speed and distortion rate of original information dissemination, improved information accuracy, and enabled employees to quickly access and share information, thereby increasing the diversity of information acquisition channels and accelerating the speed of information dissemination [
55]. Companies can utilize social networking to establish direct communication and good relationships with customers, further bringing sustainable performance to the organization [
56]. Mantymaki et al. [
57] studied how employees use corporate social networks from a knowledge management perspective and explored the value of using corporate social networks. They identified five purposes through qualitative content analysis: problem-solving, idea exploration, updates on activities, task management, and informal conversations. The use of social media can facilitate collaborative knowledge management and reduce the complexity of knowledge management through the integration of individual and collective knowledge [
58]. Zhao et al. [
59] suggest that managers should adopt an open attitude towards the use of social media. They should actively encourage employees to use social media for communication, bridging the gaps in formal communication within the organization, ensuring rapid information dissemination, and promoting effective knowledge sharing among employees.
3.3.3. Cluster Analysis
Based on the co-occurrence of keywords in the relevant literature, a cluster analysis of the keywords was conducted using the log-likelihood ratio algorithm in CiteSpace software to identify the core theories and hot topics in the theoretical knowledge. The Modularity Q value and Mean Silhouette S value of the literature clusters indicate a good clustering profile. The Cluster ID represents the post-clustering numbering, presented in the form of #0, #1, #2, and so on in the graph. The smaller the cluster number, the earlier the theme appeared, and the larger the number of labels included in the cluster, the larger the cluster size. From
Figure 7, it can be observed that the keyword clustering map displays a total of 17 reasonable cluster categories, including #0 knowledge sharing, #1 impact, #2 coordination, #3 challenge stressors, #4 popularity, #5 digital transformation, #6 social media, etc., representing the main themes in the research on enterprise social media.
Table 6 presents the top ten clusters based on the clustering results. We will discuss these ten clusters at the individual level and the organizational level.
Cluster #0 “knowledge sharing” is the largest cluster. Knowledge sharing refers to the process wherein members of an organization share their individual knowledge with other members through various forms of communication, ultimately transforming it into an organizational intellectual asset [
63]. Only by using information technology, appropriate management practices, and other means can knowledge be effectively utilized. The introduction of enterprise social media in organizations is driven by the need to improve internal communication and knowledge sharing [
64]. The motivation for sharing knowledge through social media platforms within the organization is to assist colleagues and the organization in problem-solving and goal achievement [
39]. Lam et al. [
40] advocate that social media within companies can facilitate internal and cross-organizational information exchange and knowledge sharing, further enhancing interaction between companies and customers, and improving both internal and external collaborations. Users can acquire customer knowledge from enterprise social media to enhance customer relationship management in large organizations [
65] and improve product innovation [
66]. Companies can also utilize social media to reduce information asymmetry with the market, enhance corporate transparency, and improve market efficiency [
67]. Chen et al. [
68] confirmed that knowledge sharing serves as the best mediator for workplace social media usage and employee skill improvement. However, Leonardi [
69] explicitly points out that the potential of enterprise social media in communication visibility may lead employees to conceal certain knowledge to maintain exclusive skills and competitive advantages. Lin et al. [
70] believe that when users are in an environment lacking incentives for knowledge sharing, they are more inclined to refrain from participating in community contributions, often leading to knowledge hiding behaviors. Knowledge hiding may result from various factors, such as distrust, previous non-reciprocity, negative personal relationships, prior interactions, risks to reputation or status, subject complexity, time and effort constraints, task relevance, and organizational atmosphere [
71]. Nevertheless, Ford et al. [
72] discovered that employees may simultaneously engage in both knowledge sharing and knowledge hiding.
Cluster #1, “impact”, involves keywords such as job satisfaction, work-related use, and topic analysis. The use of social media enhances job satisfaction by increasing employee engagement and organizational commitment [
73]. Social media in the workplace can have a significant impact on knowledge sharing within the organization and help members achieve professional and personal goals, resulting in substantial cost savings. The use of enterprise social media can be divided into two categories: work-related use and social-related use [
74]. Work-related use refers to employees using it for work purposes, and activities related to work may have a positive impact on their task performance and outcomes [
75]. Conversely, social-related use involves employees using enterprise social media to build and maintain social relationships. Fu et al. [
21] found that both work-related and social-related use have positive effects on social capital bonding and bridging. Furthermore, bundled social capital promotes job satisfaction, while bridging social capital inhibits job satisfaction. Eliane et al. [
76] discovered that work-related social media has no significant impact on employees’ job satisfaction, whereas social-related social media has a positive influence on job satisfaction.
Cluster #2, “coordination”, reflects the perceived task autonomy for individual employees, which indicates their perception of having a certain degree of control over the management process and decision-making freedom regarding task assignments. The use of enterprise social media requires a significant amount of time balancing task scheduling, leading to no impact on perceived task autonomy for employees [
77].
Cluster #3, “challenge stressors”, includes interruption overload, hindrance stressors, and psychological transitions. Challenge stressors are a type of stressor that can generate challenges and may lead to positive outcomes [
78]. Employees can overcome this type of stress to achieve their work goals and developmental capabilities [
79]. On the contrary, hindrance stressors arise from constraints that hinder individual developmental goals. Prevalent hindrance stressors include bureaucracy, organizational politics, job insecurity, and career stagnation [
80]. Liu et al. [
18] argue that the use of social media enriches emotional communication among employees, increases their social interaction scope, and provides them with more social support and networking resources. Consequently, this can lead to a reduction in both challenge stressors and hindrance stressors. The social use of enterprise social media during working hours can result in interruption overload and psychological transitions, which negatively impact employee well-being, creativity, and overall productivity [
81]. Harris et al. [
82] indicated that the use of social media may lead to social overload and even task overload, resulting in emotional exhaustion and tension.
Cluster #6, “social media”, emphasizes that through social media, employees can not only communicate their explicit knowledge in written form but also share tacit knowledge. Social media allows for an increasingly diverse range of knowledge-sharing activities, and actively using social media enables users to gain knowledge and information to help them solve problems [
37].
Cluster #7, “employee agility”, refers to the ability of employees to adapt to rapidly changing and unpredictable environments [
83]. Individuals can use enterprise social media to cope with unpredictable market changes [
84]. Sherehiy et al. [
85] propose autonomy, job demands, and collaboration as important strategies to promote individual agility. Lai et al. [
86] found that task autonomy significantly influences employee agility. High communication quality and trust among employees lead to high agility [
87]. The pressures related to enterprise social media can reduce the relationship between communication visibility and employee agility. However, the pressures related to enterprise social media have an insignificant moderating effect on the relationship between communication quality and employee agility [
88]. Ma et al. [
89] applied the Grounded Theory to investigate and found that the use of enterprise social media can impact employees’ work performance through work efficiency and emotional maintenance.

The Impact of Enterprise Social Media on Organizations
Cluster #4, “popularity”, reveals that key factors such as external pressure, internal readiness, expected benefits, strategic goals, and perceived risks influence the use of social media within organizations. This subsequently affects the performance outcomes in operations and marketing, as well as customer, employee, partner, and supplier satisfaction [
90]. Zhang et al. [
91] pointed out that in influencer marketing, influencer outreach is a crucial step, where brands engage with influencers and establish cooperative relationships. When customers perceive a brand as highly interactive on social media, they are more likely to purchase the brand’s products. Additionally, perceived social media interactivity has a positive influence on customer purchase, recommendation, influence, and knowledge, varying depending on the brand and social media platform type [
92].
Cluster #5, “digital transformation”, involves online social relationships, small organizations, and proactive creativity. It suggests that internal social media within organizations can help establish a flexible platform that facilitates employee communication and collaboration [
93].
Cluster #8, “critical theory”, states that media theory provides a specific perspective that explains how media shape, form, support, promote, hinder, and determine organizational communication [
94].
Cluster #9, “team boundary spanning”, involves keywords such as ESM usage regret, job reattachment, and task performance. Team boundary spanning indicates that the relationship between enterprise social media use, network structure, and content with task performance varies depending on the degree of team dispersion in terms of geography and time. The use of enterprise social media significantly influences the content and structure of individual social networks, thereby enhancing task performance. While the use of social media has certain benefits, it can also have negative impacts. For example, social media use is positively correlated with work overload, leading to reduced employee performance, and information overload in social media can affect workplace anxiety among employees [
95]. Deng et al. [
77] found that employees’ perception of task structure plays a mediating role between the use of enterprise social media and task performance.
Through the above analysis, it is found that the use of enterprise social media has both positive and negative impacts on individuals and organizations. For instance, enterprise social media can facilitate internal and external knowledge sharing [
40,
68], improve employee satisfaction [
73,
76], enhance employee agility [
84,
88], and boost overall corporate performance [
75,
77,
89]. However, it may also lead to negative effects such as knowledge hiding [
69,
72], hindrance to individual development [
81], and information overload for employees [
82]. Therefore, for different types and scales of enterprises, further research is needed to effectively enhance the positive effects and mitigate the adverse effects brought about by enterprise social media. This will enable the maximization of net benefits for employees and organizations, thereby promoting sustainable development for the enterprise.
