It proposes to model the social commerce process and outlines how Following, Communicating, Purchasing, and Sharing are systematically connected with each other in the social commerce process. The paper describes an exploratory review study using the systematic literature review method, including 384 social commerce research papers, which were published from 2011 to 2021. The data are refined by documentary analysis, including Study Selection Criteria and Quality Assessment processes. The paper systematically develops a conceptual framework for understanding social commerce. Previous research on social commerce mainly focuses on one or more particular key success factors (such as trust) in social commerce, and a few of them investigate social commerce as an integral business system. This review provides a more comprehensive basis for future social commerce research.

For a particular problem, systems thinking is a conceptual Systems 2022, 10, 56. https://doi.org/10.3390/systems10030056 https://www.mdpi.com/journal/systems Systems 2022, 10, 56 2 of 22 framework that considers the problem in its entirety [6]. Systems thinking examines the relationships between various components in a system and emphasizes the understanding of the mechanisms among these components. In a social commerce context, system thinking considers social commerce as a system and provides an integral perspective to depict complex components such as trust. This can enhance the understanding of social commerce initiatives to respond to the needs of business organizations. In order to provide a more comprehensive understanding of social commerce theory for academics, this study conducts a systematic literature review to explore the social commerce business model from a system thinking perspective and puts forward a possible theoretical explanation of why social commerce is essentially different from e-commerce. To achieve the main objective of this review, we propose three major research questions as stated below: 1. What is social commerce? 2. What are the key components of social commerce? 3. What does a social commerce system look like and how do its internal mechanisms make it different from e-commerce? Overall, the contributions of this research are as follows. First, through the analysis of 300 studies, this review proposes a more detailed social commerce components (SCCs) model compared to previous studies. This will deepen our understanding of the social commerce business model. Secondly, this paper provides a possible explanation of why social commerce is an important transformation of e-commerce. The authors propose that the network stream distribution mechanism is the key difference between social commerce and e-commerce. Lastly, this research develops a framework that includes the entire social commerce business cycle. This can be a cornerstone and starting point for future social commerce research. The remainder of this research is structured as follows. Section 2 explains the research method used in this review; Section 3 reveals the statistical results; Section 4 reports and analyzes the answers to the research questions; finally, Section 5 presents the three main conclusions of this research. 2. Methodology In this paper, a systematic literature review is conducted to describe the trend of social commerce in research and explore the social commerce business model. Meanwhile, this review is used to answer the research questions proposed in Section 1 by collecting and analyzing all the previous works in the social commerce research field that fit the pre-specified eligibility criteria. A systematic literature review is a tool for identifying, evaluating and interpreting all available research relevant to a particular research question, topic area or phenomenon of interest [7]. Systems thinking focuses on the understanding of the mechanisms among different components of a system [6]. In the social commerce context, system thinking considers social commerce as a system and provides an integral perspective to depict complex components such as trust. In this study, we apply systems thinking and use a systematic literature review to examine social commerce with the following objectives: To propose a conceptual framework of social commerce systems; To explain why social commerce is a distinct business paradigm from e-commerce by examining previous social commerce studies; To identify research gaps in current social commerce research for future study. 2.1.

Study Selection Criteria The primary reason for identifying selection criteria is to make sure that the selected articles are relevant and related to the social commerce research field. We develop a set of selection criteria as shown in Table 1. In Stage 2, we filter the studies collected in Stage Systems 2022, 10, 56 4 of 22 1 with these criteria and exclude 22,642 articles. Thus, 300 research papers remain in our database. Table 1. Inclusion and exclusion criteria.

Quality Assessment There is no generally accepted definition of ‘Quality’, but according to [8], a research’s quality relates to the extent to which the study minimizes bias, as well as its validity. Thus, we develop a quality checklist to evaluate the studies: QA1. To what extent is the article subject associated with social commerce? ( 1—low, 0—medium, 1—high) QA2. Is the research methodology specified in the article? ( 1—no, 1—specified) QA3. Is the data collection described in the article? ( 1—no, 1—described) QA4. Are the results of data analysis explained in the article? ( 1—no, 0—yes, but not well explained, 1—well explained) Each article receives a score from 4 to 4 in this quality assessment. Every study receives a label based on the total score: 4–0 for low quality, 0–2 for medium quality and 2–4 for high quality. Articles filtered by the low-quality label are excluded (735 articles), and 300 articles remain to answer the research questions (86 studies with the high-quality label and 214 studies with the medium-quality label). 3. Data Extraction and Synthesis The primary goal of this section is to extract the data and analyze the information of the selected studies in each stage. As shown in Table 2, most studies in this field appeared in the context of “social commerce”, and some studies also used the term ”s-commerce”. “Social e-commerce” and “social electronic commerce” are rarely used.

After the selection process, we sum up the publication year distribution of the 300 ar- ticles, which is presented in Figure 2. Although we have excluded studies that do not meet the criteria, we can still observe a clear increasing trend of social commerce academic publications. This increasing trend shows no sign of slowing down in 2021 since we do not include all the publications of 2021 (the search date is 25 October 2021). In particular, in 2019 and 2020, the number of social commerce publications is much higher than in previous years. Thus, we believe that social commerce research is still in an early stage and its volume will continue to experience a high level of growth. Systems 2022, 10, x FOR PEER REVIEW 5 of 22 publications.

Results In this section, we address the three research questions and answer them based on the results of Section 3. 4.1. What Is Social Commerce? Social commerce originated from e-commerce [9]. Online shopping, known as e- commerce today, emerged at the beginning of the 20th century. E-commerce needs to provide not only online business infrastructure, but also tools similar to the traditional offline commercial activities, such as word-of-mouth (WOM) advertising, bargaining, emotional implication, social shopping, etc. [10–13]. The reason for this is that the offline commercial activities are essentially emotional activities in which buyers are critical because they convey ideas, impressions or feelings about products [14]. Through these ideas or opinions, customers become the link between sellers and other potential buyers and have shown a great influence on this online business ecosystem in recent years. Thus, the customer ’s opinion is a central issue in online marketing and serves as an important signal of purchase decision making with previous transaction phenomena, such as repeat purchase and brand loyalty [15,16]. Reports show that people are more willing to make a purchase decision based on other customers’ recommendations, especially when these recommendations come from the people who they are familiar with [17]. Thus, the concept of so-called social commerce becomes more and more popular. The concept of social commerce mainly has two sources. First, social commerce is based on e-commerce. Without e-commerce, social commerce can only be a concept, which cannot be applied in commercial activities [18]. It is believed that e-commerce provides the fundamental ICT foundation of social commerce [19–21]. Secondly, social shopping is the other critical source of social commerce. Social shopping is the prototype of social commerce before social networking based on the Internet became available [11,22,23]. Some studies also conclude that the two sources of social commerce are online shopping and social networking, which is in line with our understanding [24]. In 2005, the first bloggers started to notice the upcoming changes in e-commerce and created the term “social commerce”. Rubel first defined social commerce as follows: “Social commerce can take several forms, but in sum it means creating places where people can collaborate online, get advice from trusted individuals, find goods and services and then purchase them. It shortens the research and purchasing cycle by creating a single destination driven by the power of many” [25]. The first formal definition of social commerce was given by [26]. They believe that social commerce is based on an e-commerce platform that can enable customers to collaborate with each other. Several early studies are found, as shown in Table 4. These definitions mainly focus on three aspects: E-commerce—emphasizing that social commerce comes from e-commerce and consid- ering social commerce as a new type (application) of e-commerce; Social media—considering that social media is the basis of social commerce and social media plays an important role in social commerce adoption; Systems 2022, 10, 56 7 of 22 Web 2.0—arguing that it is the Web 2.0 technology that makes social commerce a reality and Web 2.0 is the technology foundation of social commerce [27].

Since its introduction, the definition of social commerce has constantly evolved. As shown in Tables 4 and 5, early studies consider social commerce as a subset of e-commerce and believe that social commerce is a new kind of collaborative buying or social shop- ping [23]. However, as the importance of social media is gradually being recognized, some studies point out that social commerce is more than collaborative buying and social shopping. Social commerce actually is a new form of incorporating “social layers” into e-commerce or linking retail sellers to social media sites [20,31,33]. In general, with the deepening of social commerce study, researchers have incorporated e-commerce, social media and Web 2.0 technology into their studies and focused on specific components of social commerce. Essentially, the following components have been repeatedly examined: Follow. These studies focus on how eWOMs make potential customers become brand followers/fans or users [34,35]. Trust. These studies try to examine how trust is generated between sellers and buyers or among them in a social commerce context [36]. Share. These articles focus on how eWOMs transfer and spread on a social commerce platform or user communities [37]. Transaction. These studies seek to explain how UGCs on a social commerce platform lead to generating customers’ intention to buy or how customers’ purchase decisions are made in a social commerce context [38].

Other components, such as Exchange, Communication and Like, are also examined in previous studies. However, these components can be integrated into the components listed above. Although there is no standard definition of social commerce, the opinions among researchers have actually tended to be consistent: in other words, social commerce is a subset of e-commerce activities that incorporates or is realized by social media and social networks. In this study, we follow this definition temporarily and examine other questions listed at the beginning. 4.2. What Are the Key Components of Social Commerce? As shown in Section 4.1, recent research in this field focuses on particular aspects or components of social commerce, such as trust, purchase decisions, etc. We count the Systems 2022, 10, x FOR PEER REVIEW 10 of 22 keywords of social commerce in the database and display them in Figure 3. Previous studies can be classified into four main categories or components. Figure 3. Distribution of some of the most frequent key components. Notes: The vertical axis shows Figure 3.

Notes: The vertical axis shows how often these components appear in titles, abstracts and keywords. how often these components appear in titles, abstracts and keywords. 4.2.1. Following Following is one of the key components of social commerce and can be considered as the starting point of the social commerce eco-system [49]. This component is also exam- ined as Like, which indicates that a person has become a potential customer and is begin- ning to pay attention to the products and services that a company provides [34]. As shown in Figure 4, previous studies indicate that social commerce users start following a partic- ular product or service after being exposed to WOM or UGCs on social media; then, they tend to either communicate with others (become UGC creator) or go directly to purchase the products or services (become customers). Several studies focus on this particular component [35,47,49,50]. In general, Follow- ing is an intermediate component between Sharing and Communication (Transaction). It is Following (Like) that causes a WOM become a purchase intention [51]. Early studies consider Facebook and Twitter as social media or SNS, which draw people’s attention by UGCs (including WOM) and transform this attention into purchase intention by leading them to an e-commerce platform such as eBay or Amazon [47]. However, some rising content media such as TikTok have not been fully examined in a social commerce context, while businesses based on these content platforms have already become an important tool for companies to gain customers in the real business world [52]. The mechanism of Fol- lowing can be summarized as follows: • Sharing—Following: Studies analyze how UGCs (including WOM) affect potential customers’ behavior, especially how to attract potential customers’ attention to par- ticular products and services. Hairudin et al. (2019) analyze how a follower’s quality affects followers’ behavior in a social commerce context and identify five key factors, including social sharing, that affect customers’ behavior [52]. • Following—Communication: Studies in this field focus on how followers communi- cate with each other and generate content that can be used by companies to promote products and services [34]. In particular, Hofer and Aubert (2013) used data collected on Twitter to analyze how bridging and bonding social capital affect communication among followers and these social capitals can be used by companies to generate UGCs in order to build brand loyalty [53].

The reason for this is that it is widely believed that trust research as one component. The reason for this is that it is widely believed that trust comes from regular communications among users in a social commerce context [46] and communication is also the prerequisite of creating trust either among users or between buyers and sellers [43]. There are plenty of studies that focus on Communication and Trust. In general, the following questions are frequently examined in previous research. The first is how trust is generated or how communication among users can be promoted [39,54–57]. This ques- tion is considered to be important because communication and trust are critical factors that have a great influence on purchase decisions [58]. The second is to what extent this trust affects users’ purchase intention [59,60]. The last is how WOMs and UGCs affect the formation of trust [61,62]. Based on these research topics of previous studies, we can con- struct the mechanism of Communication (Trust) as shown in Figure 5. A few studies have compared the role of social e-commerce and traditional e-com- merce in promoting sales. Taking Facebook as an example, Wongkitrungrueng and As- sarut (2020) discuss the role of social commerce in promoting sales through streaming video. Their conclusion points out that, unlike traditional e-commerce, social commerce has important advantages in building trust and improving user participation. Figure 5.

Jung (2014) conducted empirical research on how social commerce website design affects followers’ purchase intention and results show that the information characteristic generally has a more significant impact on purchase intention than the visual property [49]. However, few studies can integrate other components such as Trust to exclude influences caused by factors outside the model. Figure 4. The mechanism of Following in social commerce [34,50,52]. 4.2.2.

Figure 5. The mechanism of Communication in social commerce [39,43,56,61]. Figure 5. The mechanism of Communication in social commerce [39,43,56,61]. The main importance of the mechanism of communication can be summarized as follows. Following—Communication: As mentioned in Section 4.2.1, studies in this field focus on how communication and trust are built among followers. Moreover, several studies examine the factors that affect the formation of trust among followers. Alhulail et al. (2018b) conducted empirical research and point out that reputation, satisfaction, WOM and social presence have a positive effect on trust [63]. Yahia et al. (2018) also examined a similar topic and concluded that the social habits, reputation and price advantage of users have positive impacts on trust formation, while product differentiation generally weakens the formation of trust and communication [64]. Sharing—Communication: Studies focusing on this topic seek to explain how UGCs such as customers’ reviews influence users’ behavior (Trust/Communication). Patrick et al. (2017a) examine the relationship between content shared among users (as well as that between social commerce vendors and users) and find that the perceived security and general credibility of the content have a more significant positive impact on users’ trust than susceptibility to reviews and persuasiveness [61]. Similar studies are conducted by [65,66]. Communication—Transaction: These studies seek to examine how communication and trust are transformed into a purchase decision. WOM [67], informational support and community commitment [68,69] are the main factors that transform trust and communication into a purchase decision. Moreover, Makmor et al. (2018) further confirmed that trust acts as an intermediate variable that connects social supports (emotional and informational) and purchase intention (transaction) [70].

Moreover, from the perspective of transaction, several studies conclude that peer influ- ence [83], brand relationship [84], perceived ease of use [85–87] and IT affordance [88] are also important factors that promote transaction. Following—Transaction: As examined in Section 4.2.1, studies in this field seek to explain how a purchase is generated among users. Moreover, some studies examine this question from the perspective of the culture dimension. For example, Yin et al. (2014) pointed out that intimacy among followers contributes to trust-building and both of their positive impacts on purchase intention show distinct effects in different cultures [89]. Transaction—Sharing: Studies focusing on this question attempt to examine how customers’ sharing behavior is determined [90]. For example, Ko (2018) points out that commercial desire is more influential for social sharing intentions on SNS [91]. Generally, brand co-creation [92], technical support [93] and social relations (such as guanxi) [94] are the key factors that promote customers’ sharing behavior after a purchase in a social commerce environment. 4.2.4. Sharing Sharing is the last key component found in social commerce research. In these studies, we integrate the concepts of share, recommend, spread, review and rate as the Sharing component because research in this field generally focuses on customers’ behavior after a purchase, which can still be utilized in a social commerce system. Studies that focus on Sharing mainly try to explain the following four questions. The first is how customers’ rate/review/recommend (known as the “3Rs”) behavior is determined after a transaction [92–95].

The main mechanisms of the Sharing component can be summarized as follows. The main mechanisms of the Sharing component can be summarized as follows. • Transaction—Sharing: As mentioned in Section 4.2.3, studies in this field focus on the Transaction—Sharing: As mentioned in Section 4.2.3, studies in this field focus on the influential factors that determine users’ sharing behavior after a transaction. influential factors that determine users’ sharing behavior after a transaction. • Communication—Sharing: Studies in this topic try to explain how UGCs and WOM Communication—Sharing: Studies in this topic try to explain how UGCs and WOM generated from Communication and Trust affect users’ post-purchase behavior. It is generated from Communication and Trust affect users’ post-purchase behavior. It is believed that perceived trustworthiness [85], social capital bonding [96,102] and individual capital (such as reputation and the enjoyment of helping others) [103] are the key factors that promote users’ sharing behavior. Sharing—Following: As mentioned in Section 4.2.1, studies in this field analyze how to attract potential customers’ attention to particular products and services by UGCs (including WOM). Moreover, from the perspective of Sharing, several studies focus on explaining the relationship commitment, which has a positive impact on users’ following behavior, such as customer loyalty [97,104–115]. Sharing—Transaction: Studies focusing on this question seek to examine how sharing behavior promotes other users’ purchase intention. For example, Chen et al. (2019) conducted empirical research to explain how product recommendations on social media affect users’ urge to buy impulsively [106]. Results indicate that purchase intention influenced by recommendations is determined by affective trust in the recommender and affection toward the recommended product. This conclusion is also supported by other previous research, such as [107]. However, the results presented by [97] showed that online consumer reviews do not have a direct influence on users’ intention to buy. Thus, the question of whether there is a direct relationship between Sharing and Transaction still needs further investigation. 4.3.

Figure 8. A systems thinking view of social commerce systems. A typical social commerce business cycle (closed loop) consists of four components: A typical social commerce business cycle (closed loop) consists of four components: Following, Communication, Transaction and Sharing. Social commerce completes the Following, Communication, Transaction and Sharing. Social commerce completes the connection between buyers and sellers through social media and can be summarized as a connection between buyers and sellers through social media and can be summarized as closed loop as follows: social commerce users, including potential buyers and sellers, gen- a closed loop as follows: social commerce users, including potential buyers and sellers, erate an online community based on the same value identification driven by social media; generate an online community based on the same value identification driven by social media; continuous and in-depth interactions in SNS build long-lasting relationships among users; trust attached to these social relationship can be turned into purchase intention according to previous studies; social commerce transactions are realized by a mutually accepted payment system, which is built by the e-commerce platform; buyers share the “3Rs” on social media and sellers improve products and services based on buyer ’s feedback. Based on the experience after the transaction, WOM is formed and continues to attract new potential followers (network stream). We can draw some internal mechanisms of social commerce from Figure 8. First, as shown in sub-graph I–II, new followers generate an online community in a so- cial network, which can be considered as the starting point of social commerce. Interactions among users, including potential buyers and sellers, promote the formation of customer loyalty to particular brands. Moreover, this process also can be induced by company players and its feedback is an important source of product and service improvement. Secondly, as shown in sub-graph II–III, communication on a social network generates trust among users and trust can strengthen the herd mentality before a purchasing decision is made. As shown in previous research, an online community formed by social media can amplify the conformity among users, which has already been used by many brands as an effective marketing tool. Thirdly, as shown in sub-graph III–IV, transactions led by trust will be realized by a payment system built by the e-commerce platform and the “3Rs” will be more actively produced by social commerce users compared to traditional e-commerce transactions. This is mainly because, in the social commerce context, the transaction is a kind of social activity rather than a purely business activity. Once a transaction or a brand becomes the subject of Systems 2022, 10, 56 15 of 22 an online community, the “3Rs” will continuously be created until the end of the brand life cycle. Lastly, as shown in sub-graph IV–I, the e-WOM generated by the “3Rs” will attract more potential followers and continue this social commerce business cycle. The potential new online followers are also called a network stream or traffic in some previous stud- ies [110,111]. Streaming is a concept in physics that indicates the amount of fluid flowing through a section of a closed pipe or open channel per unit time. Internet economics and e-commerce theory use this concept to refer to the online views or clicks of a specific network channel per unit time. In this study, we use this concept to refer to the number of page views (PVs) and unique visitors (UVs) on a social commerce website. Sub-graph I–IV constructs the complete social commerce system. In this model, Follow- ing, Communication, Transaction and Sharing are the key components of social commerce, which are also the main steps that social commerce users perform. Social media, the online community and the e-commerce platform are the main supporting components, which are the infrastructure of the social commerce system. Moreover, followers, fans, customers, KOLs, cyberstars and companies are the main players on the social commerce platform. We can thus obtain the answer regarding the difference between social commerce and e-commerce. The main difference between social commerce and e-commerce is shown in Figure 9. In the traditional e-commerce context, an e-commerce platform has deci- sive power in allocating a network stream through the search engines that they develop. This centralized mode of network stream allocation has caused e-commerce platforms to become huge, such as Alibaba and Amazon, which benefit from these “economies of scale” [108,109]. Although e-commerce platforms and social media still play a critical role in the social commerce context, they have no decisive power to allocate a network stream, i.e., social commerce users (buyers and sellers) connect with each other on their Systems 2022, 10, x FOR PEER REVIEW 16 of 22 own. This fundamental difference is an important sign of social commerce as a new kind of online business. Figure 9. The transformation from e-commerce to social commerce. Figure 9.

Conclusions As shown in the Results section, in the social commerce context, systems thinking considers social commerce as a system and provides an integral perspective to depict com- plex components. From the systems thinking point of view, we categorize all components of social commerce systems identified in previous publications to further investigate the relationships among different components of social commerce systems and propose a con- ceptual framework of social commerce systems. Some interesting conclusions can be drawn from this study. First, social commerce is an important evolution from e-commerce. Many previous studies consider social commerce as a subset of traditional e-commerce [21,110,112,116]. However, in this study, we believe that social commerce is a new form of online business that is essentially different from the traditional e-commerce that we are familiar with. Future research can be conducted from the perspective of social commerce as a new form of online business rather than a subset of traditional e- commerce. Secondly, social commerce is changing the foundation of online marketing. As has already been widely accepted, e-commerce represents a paradigm shift as a “disruptive” innovation that is radically changing the traditional ways of doing business [113]. Social commerce may be a “disruptive” innovation that is changing the traditional e-commerce methods of doing business, rather than an alternative means of online marketing. Social commerce is an emerging trend in which sellers are connected by online social networks [114], and this has changed the core of marketing from brand recognition to community recognition and from brand management to relationship management [84,114]. This shift in social commerce has turned traditional online marketing into e-marketing or digital marketing, which is completely data-driven. Further marketing studies should not ignore this fundamental change brought about by social commerce. Lastly, social commerce will promote the implementation of a C2B model. The most important aspect for companies engaging in business activities in the social commerce context is relationship operation. The core of relationship operation is to achieve continu- ous and in-depth interaction with customers in order to establish emotional relationships Systems 2022, 10, 56 16 of 22 5. Conclusions As shown in the Results section, in the social commerce context, systems thinking con- siders social commerce as a system and provides an integral perspective to depict complex components. From the systems thinking point of view, we categorize all components of so- cial commerce systems identified in previous publications to further investigate the relation- ships among different components of social commerce systems and propose a conceptual framework of social commerce systems.

Social commerce may be a “disruptive” innovation that is changing the traditional e-commerce methods of doing business, rather than an alternative means of online marketing. So- cial commerce is an emerging trend in which sellers are connected by online social net- works [114], and this has changed the core of marketing from brand recognition to commu- nity recognition and from brand management to relationship management [84,114]. This shift in social commerce has turned traditional online marketing into e-marketing or digital marketing, which is completely data-driven. Further marketing studies should not ignore this fundamental change brought about by social commerce. Lastly, social commerce will promote the implementation of a C2B model. The most important aspect for companies engaging in business activities in the social commerce context is relationship operation. The core of relationship operation is to achieve continuous and in-depth interaction with customers in order to establish emotional relationships and value recognition. In this process, users’ in-depth involvement in product development, design and improvement is the prototype of a demand-driven production and operation model (C2B). In this model, companies need to be “closer” to their users, and start the initial integration of crowd-funding, crowd-creating and crowd-sourcing. The distinction between producers, communicators and consumers in the traditional economy will become blurred in social commerce, in which online community participants are “active producers”, “faithful consumers” and “enthusiastic communicators” at the same time. It can be seen that in the social commerce context, consumers and their communities are the promoters of business activities, and the C2B model is easier to be implemented under the influence of SNS and social media. Future research should start from the specific mechanisms of how social commerce promotes the C2B model. 6. Discussions This study proposes a social commerce business model framework by conducting a systematic literature review. The main contributions of this paper are as follows. Compared to research focusing on social commerce constructs, this study proposes a more detailed SCC model. Previous studies generally consider social commerce as composed of a social component and commercial component [117–119] and try to establish a social commerce model by examining how a particular factor, such as trust, is affected by social support [120]. Based on previous studies, this paper integrates current key factors that are involved in social commerce and builds a more comprehensive model that includes Following, Communicating, Purchasing and Sharing. This model can deepen the current understanding of social commerce systems. Compared to previous literature review studies of social commerce, this paper focuses on explaining why social commerce is an important transformation from e-commerce. Previous studies focus on social commerce adoption [121,122], social commerce character- Systems 2022, 10, 56 17 of 22 istics/topics [2,4,48,80] and consumers’ behavior [123–125]. Based on these studies, this paper further proposes a network traffic distribution mechanism as the key difference between e-commerce and social commerce, and this makes social commerce an important evolution of e-commerce. Compared to other social commerce frameworks or conceptual model research, this study develops a theoretical framework that includes the entire social commerce business cycle. Previous studies are relatively scattered and mainly focus on one or two particular components of social commerce, such as trust and social commerce adoption [110,126,127], the influencing factors of online marketing [114], customer satisfaction [128], social com- merce website design [129–131] and C2C social commerce [132–134]. Based on previous works, this study constructs a more integral social commerce theoretical framework that contains all social commerce activities examined before. This provides a more comprehen- sive basis for future social commerce research. The main limitation of this study is that the transformation of social commerce has not fully been examined through real business cases. In reality, this transformation process may be unclear, as some traditional e-commerce platforms are also integrating social elements, such as Alibaba’s live-broadcast shopping. However, as mentioned in this paper, the network traffic distribution mechanism is fundamentally different between social commerce and e-commerce. Based on this limitation, more in-depth research in the future can be started by conducting more detailed social commerce case studies to provide more concrete real business evidence.
