Abstract: Job characteristics are work-related factors or attributes, which have important effect on workers’ physical and mental health. Comparative study found that while job characteristics in DC Model were divided into three relatively specific dimensions: job demands, job control and social support; JD-R Model was distinctive in classifying job characteristics into two more general categories of job demands and job resources. Nevertheless, the outcome variables DC model and JD-R model focused on workers’ physical and mental health as well as organizational performance; moreover, both of the two models highlighted the effect of job characteristics on workers. Future research should explore in depth the important role of core job characteristics and combinations of different job resources and demands in different occupations as well as their applicability to individual traits and citizen groups in our country, and finally try to apply the results of research to the practice of job redesign in order to promote the occupational health of workers.

Key words: Job Characteristics, DC Model, JD-R Model
