This paper explores the culture traits of organizational justice and organizational trust in Chinese context, and their influence on the formation mechanism of cohesion in Chinese enterprises, adopting both qualitative and quantitative approaches. The qualitative study finds that organizational justice and organizational trust have both instrumental and affective characteristics in Chinese context. Following the process of “perceptionjudgmentpreference”, cohesion can be developed through both instrumental and affective approaches. To verify these points in Chinese context, this paper utilizes questionnaire survey. The findings support that cohesion can be affected by organizational justice and organizational trust, and confirm that leader trust plays a fully mediating role in system trust’s influence on task cohesion and in distributive justice’s influence on interpersonal cohesion in Chinese context. The conclusion implies that leadership behavior in Chinese enterprises has direct determining effect on organization effectiveness and distribution fairness.
