A nationwide survey (N= 396) was conducted on occupational commitment of journalists in China. Occupational commitment consists of three dimensions: emotional commitment, continuous commitment and normative commitment. The result shows that journalists have a medium level of occupational commitment, in which continuance commitment is relatively high, and affective commitment and normative commitment are both relatively low. Three categories of factors affect those occupational commitments. Among the factors of work experience, journalism education and job satisfaction have a significant positive effect on occupational commitment; among the factors of professional aspiration crisis, media roles and ideal news outlets have a significant effect; among the factors of occupational expectancyvalue, video skills, hygiene factors, prestige status factors and development factors have a significant positive effect, while perceived opportunities have a negative impact. Work experience and professional aspiration crisis not only have a direct effect on occupational commitment, but also have an indirect effect by affecting the expectancy-value factors.
