The purpose of this paper is to study enterprise innovation in the perspective of external supplier relationship. On this purpose, this paper examines the impact of supplier change on enterprise innovation with the moderating role of market competition.

Using 2012–2020 empirical data of Chinese listed manufacturing enterprises, this paper investigates the relationship among supplier change, market competition and enterprise innovation through a two-way interaction model.

The results show that supplier change has a negative impact on enterprise innovation. And market competition intensifies the negative relationship between supplier change and enterprise innovation. Additional analyses indicate that the main effect and the moderating effect are more significant when the enterprise is non-state-owned or has lower ownership concentration.

This paper studies enterprise innovation from the perspective of external stakeholders. It focuses on supplier relationship in a dynamic variation view, instead of the traditional static ones. Moreover, this paper explores the contingency effect of market competition and gives practical implications for managers to adjust innovation strategy flexibly.

Influencers’ vlogs have the potential to impact consumer behaviors through vlog-embedded corporate sponsorship and brand collaborations. However, even without brand involvement, vlogs can also “unintentionally” benefit influencers as a relationship-building tool. This study is designed to investigate the relationship between vlog-viewing and audiences’ purchase behaviors of influencer-recommended products through the impacts of influencer–follower interactions, perceived influencer credibility and parasocial relationships.

An influencer-disseminated online survey was conducted in collaboration with a YouTube celebrity among N = 948 of her 72.6 K subscribers. Statistical analysis was performed through structural equation modeling (SEM) on SPSS Amos.

SEM results indicated that the extent to which participants liked the vlogs had both a direct impact on their purchase behaviors and secondary impact through social media engagement, parasocial relationships and perceived influencer credibility.

The study expands current research and understanding of influencer marketing. Brands and social media content creators are advised to rethink vlogs as a creative genre for long-term brand–influencer collaborations and implicit social media endorsements.

Influencer marketing is a newer interactive marketing model that has attracted the attention of scholars and marketers. The study aimed to examine the mediation role of influencer credibility (IC) and the moderation role of self-esteem in the effects of individuals' parasocial relationships (PSR) with YouTube influencers on their product attitudes (PATs) and purchase intentions (PIs).

The researchers used an online survey to test a sequential mediation model and moderation mediation models using Hayes PROCESS modeling.

The researchers revealed a sequential mediation model that IC and PAT mediate the association between PSR and PI. Individuals who perceived IC to be low were more likely to buy an endorsed product when their self-esteem got lower. When their self-esteem is low, individuals tend to purchase the endorsed products if they have stronger PSR with the influencers. However, they are less likely to buy the endorsed products when their self-esteem gets higher.

The study expands the dimensions of IC. The persuasive power of IC and influencer-user relationship was affected by individual differences, namely, self-esteem. Brands should pay attention to customers' personalities, motivations and preferences when designing strategies to market their products via social media.

As YouTubers began to create videos about their personal experience of using products, these video testimonials have become a powerful form of electronic word-of-mouth (eWOM). This study aims to investigate the mediating role of self-effect and third-person effect in the relationships between eWOM seeking and passing along YouTube product review videos (video-based eWOM – vWOM) as a specific form of eWOM.

The paper used a survey to interview a total of 282 respondents at a public university in the Midwest USA with about 18,000 students.

The results show that perceived third-person effect leads to sharing more positive vWOM, while perceived self-effect results in a high likelihood of passing along negative vWOM. The general eWOM consumption does not have a direct effect on the sharing of vWOM. In addition, the YouTube sharing habit contributes to sharing vWOM regardless of valence.

The results provide marketers’ insights on how to utilize the social media such as YouTube to improve the visibility of promotional brand messages. Sharing of positive vWOM is due to perceived third-person effect (presumed influence), but sharing negative vWOM is due to perceived self-effect. It also suggests marketers take immediate remedial measures to avoid spreading of negative reviews to other users because if viewers are persuaded to think it could happen to themselves as well, they will spread the video.

The paper has theoretical implications. It contributes to the third-person effect and presumed influence literature by exploring its role in spreading the word for products. It also fills the gap in effects of eWOM literature by examining the mediating role of the valence of video-based eWOM in the spread of eWOM.

A sol-gel process has been successfully utilized to form hybrid materials of poly(vinyl butyral) (PVB) and zirconium dioxide (zirconia). The gelation occurred due to the interaction between remaining hydroxyl group of PVB and zirconia. The hybrids showed good optical transparency and significant improvement in Young's modulus, dynamic mechanical property, abrasion resistance and impact resistance. The glass transition temperature of PVB shifted to higher temperatures by hybridization of PVB and zirconia.

Based on path–goal theory and social learning theory, this research is aimed at investigating how authentic leadership can influence team performance in virtual teams, specifically the mechanisms through the mediator of high-quality interpersonal relationships and the moderator of task interdependence.

The valid data of this research were collected from 90 virtual teams including 388 team members and their 90 leaders with a time-lag in China, and then the data were mainly analyzed by the hierarchical multiple regression and bootstrapping method to test the hypotheses.

The research results reveal that authentic leadership can positively influence virtual team performance. High-quality interpersonal relationships mediate the relationship between authentic leadership and virtual team performance. Furthermore, the indirect relationship between authentic leadership and virtual team performance via high-quality interpersonal relationships is moderated by task interdependence.

Team performance as an important kind of team effectiveness is crucial to the virtual team's advantage and success. This research enriches the knowledge on the relationship between authentic leadership and virtual team performance, which contributes to the virtual leadership effectiveness and virtual team management.

The purpose of this paper is to investigate the mechanism through which stressors influence job crafting. Based on regulatory focus theory, this study explores the mediating role of work regulatory focus between the challenge-hindrance stressors and approach-avoidance job crafting and the moderating role of trait regulatory focus.

The authors collected survey data in a northwestern city of China from 578 employees working in the finance, real estate and IT industries. Results were analyzed using Mplus 7.

The results reveal that challenge stressors have a positive effect on both approach job crafting (i.e. increasing structural job resources, increasing social job resources and increasing challenging job demands) and avoidance job crafting (i.e. decreasing hindering job demands) via work promotion focus. On the other hand, hindrance stressors have a positive effect on only avoidance job crafting via work prevention focus. In addition, trait promotion focus accentuates the influence of challenge-hindrance stressors on work regulatory focus, as well as the indirect effect of challenge-hindrance stressors on approach-avoidance job crafting respectively. Trait prevention focus only weakens the influence of challenge stressors on work promotion focus.

This study unfolds how stressors relate to job crafting. However, the cross-sectional design may limit the causal inferences.

This study provides new insight into the relationship between stressors and job crafting by explicating the motivational mechanism and boundary conditions.
