Abstract: Based on a largescale survey completed in 1999 in urban Tianjin， we have explored the substantive functions of social network resources in job matching. Our major findings are： (1) people with less human and political capital but at a higher economic status tend to frequently utilize social network resources to fulfill their occupational mobility； (2) job searchers using social networks are less efficient but target higher incomes than those who do not depend upon such networks； (3) the direction of job mobility through social networks is from government agencies and stateowned enterprises to self or collectiveowned companies， international joint ventures， foreign firms， neweconomy agencies， or other market sectors with no administration at superior levels； and (4) utilization of social network resources has no significant effects on job matching.

Key words: social network, network resources, job matching, jobsearch efficiency, targeted incomes
