Based on uncertainty reduction theory, this study explores how perceived information transparency mitigates users' perceived uncertainty, which in turn influences their actual purchase behavior. In addition, the moderating effects of cultural tightness on the relationship between perceived information transparency and perceived uncertainty are also considered.

Users with the shopping experience on Xiaohongshu are invited to participate in the survey. Finally, 355 valid longitudinal data are collected.

The results indicate that the three dimensions of perceived information transparency (i.e. perceived product transparency, perceived seller transparency and perceived transaction transparency) can reduce users' perceived uncertainty significantly. Besides, the negative impacts of perceived product and seller transparency on users' perceived uncertainty are stronger when cultural tightness is higher. However, cultural tightness does not moderate the relationship between perceived transaction transparency and users' perceived uncertainty.

First, the authors' research extends the uncertainty reduction theory to the context of social commerce. Second, the authors' research explores the boundary condition under which perceived information transparency varies by identifying cultural tightness as the moderator of the relationship between perceived information transparency and uncertainty. Third, the authors' research enriches the understanding of the cultural tightness of China.

The paper explores how social networks influence Cameroonian consumers' buying behavior. Then, the authors examine customers' advertising perceptions and psychological dispositions to explain their purchase intention and behavioral consumption.

The research framework is developed based on Nelson's theory of advertising by studying advertising perceptions, consumer psychological dispositions associated with social network characteristics and behavioral consumption. Using partial least squares structural equation modeling (PLS-SEM), the validation takes support from 231 responses collected with an online questionnaire from Cameroun.

The study reveals three critical results: (1) consumers' perceptions of advertising significantly influence their psychological disposition, (2) consumers' psychological dispositions and the social network significantly influence their intention to purchase and (3) consumers' intention to purchase significantly impacts their behavioral consumption.

The proposed and validated model contributes to understanding the influence of social network communication on customers' buying behavior on social s-Commerce platforms of developing country enterprises.

This study aims to address how to facilitate more community members making purchases in social commerce communities. The research is expected to shed new light on the underlying process by which individuals’ social networks influence their purchases in social commerce communities.

An online survey and secondary archive data are presented to confirm all the hypotheses.

Community members’ out-degree ties show a positive effect on their attachment to other members, as well as to the community. Community members’ attachment to the community has a positive influence on their purchases made in the e-commerce modules of social commerce communities and mediates the effect of their attachment to community members. The study establishes a theoretical framework to reveal how community members’ social networks influence their purchases in social commerce communities.

The findings of this study provide new insights for managers and designers of new social commerce communities to inspire them to achieve their goal of keeping consumers making purchases in the e-commerce modules of social commerce communities.

Firstly, this study draws on attachment theory to explain why community members make purchases in a social commerce community. Then, the study enriches the research on social network ties and attachment theory by initially integrating the social network perspective with attachment theory to examine the effects of social network ties on different types of attachment.

Drawing on social network and information diffusion theories, the authors study the impact of the structural characteristics of a seller’s local social network on her promotion effectiveness in social commerce.

The authors define a local social network as one formed by a focal seller, her directly connected users and all links among these users. Using data from a large social commerce website in China, the authors build econometric models to investigate how the density, grouping and centralization of local social networks affect the number of likes received by products posted by sellers.

Local social networks with low density, grouping and centralization are associated with more likes on sellers’ posted products. The negative effects of grouping and centralization are reduced when density is high.

The paper deepens the understanding of the determinants of social commerce success from a network structure perspective. In particular, it draws attention to the role of sellers’ local social networks, forming a foundation for future research on social commerce.

As a derivative model of e-commerce, social commerce has received increasing attention in recent years. Empirical studies on social commerce have examined the key factors that influence users' attitudes or adoption intentions, but their conclusions are context-based and are not entirely consistent. This study aims to draw a general conclusion by systematically synthesizing the findings of previous studies and examine whether cultural differences play a moderating role in users' social commerce adoption.

A meta-analysis based on 11,786 independent samples from 39 empirical studies was conducted to integrate their results and develop a comprehensive conceptual model. A moderator analysis was carried out to investigate the moderating effect of culture by dividing the context into subgroups of individualistic and collectivistic cultures.

The results show that this comprehensive conceptual model can help better understand the adoption of social commerce. Meanwhile, the moderator analysis indicates that cultural differences have a significant moderating effect on the relationship between the determinants and the adoption of social commerce.

The findings of this paper have theoretical implications and make managerial contributions.

Widespread technology adoption in tourism enables tourists to be active content creators, thus, influencing destination brands through co-creation. This study examines value co-creation, social commerce information sharing, and destination brand equity.

A quantitative approach was applied to analyse data collected from a global online survey. Hypotheses were tested using PLS-SEM analysis.

Results show that destination brand equity is positively influenced by value co-creation. Additionally, social commerce information sharing mediates the relationship between value co-creation and destination brand equity.

The article adds new insights to tourism marketing by investigating value co-creation, social commerce information sharing and destination brand equity. It also offers interesting implications for destination managers to improve Vietnam as a destination brand.

This paper is among the first to test the mediating role of social commerce on value co-creation and destination brand equity.

Entrepreneurs and individual sellers heavily leverage their social ties embedded in social media, expressive or instrumental, to penetrate the market and achieve business success. However, the extant social commerce literature offers limited understanding on how different forms of buyer−seller social ties embedded in social media affect buyers' purchase behaviors. The study draws on the theoretical lens of social ties and proposes an integrative theoretical framework to understand the direct and indirect influences of expressive and instrumental ties (ExTSM and InTSM) between buyers and sellers on buyers' purchase intention (PI) in social commerce.

The authors first validated the measures of ExTSM and InTSM with survey data from 166 Weibo commerce buyers. They then tested their theoretical framework and hypotheses with survey data from 246 buyer−seller dyads in WeChat commerce.

With a buyer-centric view, (1) ExTSM and InTSM, respectively, had a direct negative and a positive influence on PI; (2) both trust and perceived product value displayed inconsistent mediation effects on the negative relationship between ExTSM and PI; and (3) only perceived product value mediated the positive influence of InTSM on PI. From sellers' viewpoint, (1) their ExTSM and InTSM with buyers were mixed up, and (2) the mingled social ties negatively impacted buyers' purchase intention.

The findings of the study advance the theoretical understanding of social commerce and offer practical guidance for small and medium-sized enterprises to effectively utilize social media for business purposes.

The purpose of this study was to understand consumers' continuance intention to purchase in social commerce from an integrated perspective of the expectation confirmation model (ECM) and information adoption model (IAM). Moreover, the cultural difference between the United States and China was explored in the integrated model.

A total of 1,589 responses were collected from American (n = 725) and Chinese consumers (n = 864). The partial least squares structural equation modeling (PLS-SEM) was applied to perform measurement assessment, structural model and multiple group analysis.

Results showed that consumers' continuance intention to purchase in social commerce was significantly predicted by the integrated model. Within the ECM, confirmation of expectations positively affected information usefulness and satisfaction, and information usefulness positively influenced satisfaction, which further led to continuance intention. Moreover, within the IAM, both argument quality and source credibility positively affect information usefulness, which leads to information adoption and continuance intention to purchase in social commerce. In addition, the influences of information usefulness on information adoption and continuance intention to purchase in social commerce were stronger for American consumers.

The findings of this study gain a better understanding of consumers' decision-making process and cultural differences between American and Chinese consumers.

This study investigates how social interaction-oriented content in broadcasters' live speech affects broadcast viewers' purchasing and gift-giving behaviors and how broadcaster popularity moderates social interaction-oriented content's effect on the two different behaviors in live-streaming commerce.

A research model was proposed and empirically tested using a panel data set collected from 537 live streams via Douyin (the Chinese version of TikTok), one of the most popular live broadcast platforms in China. A fixed-effects negative binomial regression model was used to examine the proposed research model.

This study's results show that social interaction-oriented content in broadcasters' live speech has an inverted U-shaped relationship with broadcast viewers' purchasing behavior and shares a positive linear relationship with viewers' gift-giving behavior. Furthermore, broadcaster popularity significantly moderates the effect of social interaction-oriented content on viewers' purchasing and gift-giving behaviors.

This research enriches the literature on live-streaming commerce by investigating how social interaction-oriented content in broadcasters' live speech affects broadcast viewers' product-purchasing and gift-giving behaviors from the perspective of broadcast viewers' attention. Moreover, this study provides some practical guidelines for developing live speech content in the live-streaming commerce context.

In recent years, the proliferation of social commerce (s-commerce) has attracted many researchers to investigate the drivers of individuals' intentions. However, the empirical results reported in these studies were fragmented and inconsistent. This has led various meta-analyses to synthesize these findings, but without including a large number of s-commerce studies. In addition, investigating meta-analytically the effects of moderators such as the six dimensions of Hofstede's national culture is still lacking.

Drawing on nine theories and models, this meta-analysis aims to summarize the findings reported in 109 s-commerce studies published between 2011 and 2021 and to examine the moderating role of national culture. The correlation coefficient (r) has been used as the main effect size for this study. Based on the random-effects method, the CMA V3 software has been employed to calculate the weighted mean effect sizes.

The meta-analysis results showed that all the 11 hypothesized direct relationships are positive and significant. The moderator results also revealed that five out of six cultural dimensions significantly moderate the examined associations.

This research serves to enrich the existing s-commerce literature by addressing contradictory and mixed results reported in the empirical studies. This study is one of the first of its kind to investigate the role of Hofstede's six cultural dimensions as moderators in the field of s-commerce using the meta-analytic techniques.
