Abstract:By means of questionnaire survey data collected , with a valid sample of 592 employees, the paper studies the influence of Mianzi consciousness on knowledge sharing behavior and employee creativity. The empirical research discoveries that employee’s desire to gain Mianzi has a positive effect on knowledge donating, then has a positive effect on creativity mediated by knowledge donating; employee’s fear of losing Mianzi has a negative effect on knowledge collecting and knowledge donating, then has a negative effect on creativity mediated by knowledge collecting and knowledge donating. Moreover, supportive organizational communication climate moderated the relationship between Mianzi consciousness and knowledge sharing. If Chinese managers fully understand and reasonably use this mechanism of Mianzi consciousness on knowledge sharing behavior and creativity, the efficiency of knowledge management and organizational innovation performance can be enhanced.
