Abstract

Abstract:

Based on the job demand-resource theory, this study explores the internal mechanism of the impact of two social media usage purposes on employees' job performance, and then analyzes the impact of two social media usage purposes on employees' job performance. Using 369 matching data on “leaders-subordinates”, the study found: (1) work- and social-based social media usage improved employees’ job performance; (2) work- and social-based social media usage affected job performance through work engagement, and social-based social media usage affected job performance through relationship conflict; (3) the effects of work- and social-based usage of social media on employees’ job performance were mutually substitutive. The results of this study not only theoretically expand the research perspective of social media usage and provide a new theoretical framework for follow-up research, but also provide new ideas for organization management of social media usage through comparative analyses.

Key words: social media usage, work state, interpersonal relationship, job performance
