As an emerging collaboration platform based on web 2.0 technologies, enterprise social media can provide opportunities and challenges for information acquisition and creativity development. However, existing research on the ways in which enterprise social media use affects employee creativity from both internal and external team perspectives is rather limited. Using communication visibility theory (CVR), this paper proposes a research model for investigating the relationship between enterprise social media (ESM) usage and employee creativity. Drawing on an analysis of 218 employees' data, this study found that ESM, when used for both work and social purposes, has a positive effect on internal information exchange within teams and external knowledge acquisition across teams, which further contributes to employee creativity. Innovative culture can weaken the relationship between work-related ESM usage and internal team information exchange, and strengthen the relationship between social-related ESM usage and internal team information exchange. The findings suggest means of using enterprise social media for specific purposes to increase creativity and innovation in organizations. [ABSTRACT FROM AUTHOR]

An increasing number of employees are using social media for their daily work. But the relationship between social media use and job performance is controversial. To address this issue, this study explores the impact of different social media platform usage on job performance based on different usage purposes. The media synchronicity theory provides the theoretical foundation. Surveys were conducted in an Internet commerce company in China, generating 301 valid responses for analysis. The results showed that both work-related and social-related use of enterprise social media had a U-shape effect on job performance. Also, work-related use of general social media had a U-shape effect on job performance, whereas social-related use of general social media had no effect on job performance. These results offer insights about how organisations may guide their employees in their use of social media to improve job performance. [ABSTRACT FROM AUTHOR]
