This paper employs social network, social capital and intra-organizational conflict perspectives to examine an important topic in mass communication field: the relationship between journalists and their news sources. The major findings are: (1) In a hierarchical organization, middle-level employees or managers, rather than top executives or official speak persons, are most likely to be journalists' main sources. (2) Strong ties between reporters and sources can facilitate the information flow and help the former get inside news. (3) Reporters themselves can be "bridges", providing valuable information for their sources and hence enhancing their status. (4) Personal ties between reporters and their sources do not necessarily do harm to journalists' professional ethics; on the contrary, these linkages may be critical to freedom of press. Theoretical and practical implications are also discussed.
