WeChat is one of the most popular social media platforms in China and has more than 1 billion daily active users ( Blog.Wechat, 2019). Despite the increase in social media research in recent years, few studies have focused on Weibo, WeChat, and QQ. Different from the most popular social media platforms in Western countries, Weibo, WeChat, QQ, and Qzone are the most popular social media platforms for communication and information seeking in China ( Hussain et al., 2020). Current studies mainly focused on the popular social media in Western countries such as Facebook and Twitter. A few researchers have concentrated on Facebook use to explore core knowledge ( Shiau et al., 2018) and privacy issues ( Chou et al., 2019). (2016) revealed that Japanese users changed their habits when they experienced information overload on Twitter. (2015) investigated Facebook users and found that privacy concerns and confidence are important predictors for social media fatigue. Recent studies played a lot attention to explore the use of social media. (2018) indicated that when social media use exceeds the optimal level at work, it will cause overload, which can affect job performance. In the workplace, employees who excessively access social media may feel conflicted between work and life, as well as stress and reduced well-being ( Zheng and Lee, 2016), which may negatively affect their job performance ( Brooks, 2015). Some scholars have studied the impacts of excessive social media use. However, frequently using social media may not always be beneficial. In addition, different forms of knowledge sharing on social media can help people develop ideas ( Panahi et al., 2016a). Many studies have shown that using social media platforms can enhance individual job performance and productivity in the workplace ( Aral et al., 2013 Moqbel et al., 2013 Alalwan et al., 2017 Cao and Ali, 2018). In organizations, employees use many social media platforms for sharing and communicating ( Yu et al., 2018). The China Internet Network Information Center (CNNIC) released the social media users' behavior research report, which found that enterprise/company employee respondents accounted for 31% of social media users, which was the highest percentage of all users. Social media is used for personal activities as well as in the workplace. Thus, social media provides great opportunities to communicate and share. For example, individuals can upload their own edited content on social media, and others can comment on the shared content. People can share ideas, pictures, and comments by interacting with others on social media ( Alshahrani and Pennington, 2018). Social media brings a great convenience as people can use it any time for entertainment, communication, and information. Owing to the rapid development of mobile technology and popularity of smart devices, social media plays an important role in people's daily lives. The implications and limitations of this study and future research on excessive-use behavior are also discussed.


These findings, obtained by theoretically and empirically investigating the positive outcomes of excessive WeChat use, suggest an upside to excessive WeChat use. A survey of 364 employees revealed that excessive WeChat use directly promotes creativity and indirectly improves creativity via knowledge sharing, but excessive WeChat use does not lead to psychological strain. We used the structural equation model to test our research model. Based on the person–environment fit model and motivation theory, this study examined the three paths of excessive WeChat use affecting individuals' creativity in workplace. This study explored the direct and indirect impact of excessive use of WeChat on individuals' creativity in workplace, focusing on how excessive use of WeChat promotes or restrains creativity through knowledge sharing and psychological strain.

The pervasive nature of social media can result in excessive use and addiction, but whether excessive use of social media is good or bad for individuals' creativity is unclear.
