Whether conflicts among TMT members could be effectively resolved is one of important factors influencing firm performances.  Rather than investigating demographic information that has been heavily researched in existing literature, the impact of TMT members' value congruence on the two types of conflicts (task-type and of relationtype conflicts) were examined theoretically.   TMT data collected in 118 firms from telecom industry were analyzed.  It is found that value the congruence would influence relation-type conflicts among TMT members negatively, which in turn, have impacts on employee outcomes.  The moderating effects of firm environment were also tested.  Results show that negative influence of relation-type conflicts between TMT members becomes stronger in a competitive firm environment than in a less competitive firm one.
