We examine the relationships among perceived organizational justice, trust, and organizational citizenship behavior (OCB) of workers in joint ventures (JVs) and state-owned enterprises (SOEs) in China. We hypothesize different dimensions of organizational justice are related to trust in organization and trust in supervisor, which will in turn affect workers' OCB. Some of these relationships are hypothesized to be different in SOEs and JVs owing to the differences in management practices and employment relationships between them. Our hypotheses are tested on data collected from 295 supervisor-subordinate dyads in a JV and 253 such dyads in an SOE. The analyses reveal that (1) the positive effect of distributive justice on trust in organization is stronger in JVs than in SOEs, (2) the positive effect of procedure justice on trust on organization is stronger in SOEs than in JVs, (3) the effect of interaction justice on trust in supervisor is similar for both types of organization; (4) trust in organization affects OCB in both SOEs and JVs, and (5) trust in supervisor affects OCB in JVs only. © 2006 Elsevier Inc.
