A major challenge confronting online retailers is that of stimulating consumer online purchase intention. Many studies have explored the factors that affect consumer purchase behavior; however, few have described the underlying mechanism that links the online shopping experience to social ties and the effect of their strength on purchase intentions. This study adapted the stimuli–organism–response (S–O–R) model to analyze the effects of the online shopping experience on customer involvement and online purchase intention under conditions of weak and strong social ties. Two quasi-experiments were conducted to test the research model and hypotheses. The results showed that online shopping experience had a positive effect on customer involvement, and this involvement in turn had a positive effect on online purchase intention in the strong-tie group and the weak-tie group. Cognitive and affective involvement played partial mediating roles between the online shopping experience and online purchase intention in the weak-ties group and full mediating roles in the strong-ties group. The effects of online shopping experience on customer involvement and online purchase intention differed between the two tie strength groups. The implications of these findings for researchers and practitioners are discussed.

PurposeEnterprise social media (ESM) are frequently used in enterprises for daily operation. Although many researchers have attempted to understand the antecedents and consequences of ESM use, the integrated model, boundary conditions and mechanism of the impact of ESM use on performance are still unclear. This study fill this research gap by adopting a grounded theory approach to study how ESM use affects employee performance.Design/methodology/approachChoosing representative cases, the authors collected interview data and analyzed the data using open coding, axial coding and selective coding.FindingsThe results showed four main categories including ESM use, work efficiency, emotional maintenance and work performance, as well as 14 sub-categories. This paper also constructs a model of the impact of ESM use on work performance. In addition, results showed that ESM use affects employees' work performance through work efficiency and emotional maintenance, and frequency of use and individual characteristics may moderate this process.Originality/valueThis study’s results contribute to the existing ESM literature by finding the integrated model, boundary conditions and mechanism of the impact of ESM use on performance. The authors also contributed to the social media literature by finding 14 sub-categories and four main categories including ESM use, work efficiency, emotional maintenance and work performance. The conclusion of this paper provides guidance and reference for the use and management of internal social media in enterprises.

PurposeThe purpose of the present study is to build a research model to study how the use of different enterprise social media platforms affects employees' relationship capital, and the moderating role of innovation culture is also examined.Design/methodology/approachStructural equation modeling was performed to test the research model and hypotheses. Surveys were conducted in an electronic commerce company in China that uses different social media platforms, generating 301 valid responses for analysis.FindingsFirst, private social media used for work-related purposes can contribute to employees' relationship capital, and public social media QQ used for work-related purposes can contribute to employees' communication quality. WeChat used for social-related purposes has a positive effect on employees' information exchange. Second, innovation culture acts as a positive moderator between work-related media use and employees' information exchange, while innovation culture acts as a negative moderator between social-related WeChat use and employees' information exchange. Third, innovation culture acts as a positive moderator between work-related QQ use and employees' trust, while innovation culture acts as a negative moderator between social-related QQ use and employees' trust.Originality/valueFirst, this paper contributes to the information system (IS) social media literature by studying the effect of the use of different enterprise social media platforms used for different purposes on employees' relationship capital. Second, the authors contribute to relationship capital theory by clarifying that use of public and private social media platforms for social- and work-related purposes is an important driver of the formation of employees' relational capital. Third, the present study also contributes to enterprise social media literature by confirming that innovation culture acts as a different moderator between use of different enterprise social media platforms and employees' relationship capital.
