This paper tries to build up an inherent analytical framework on information concealment based on the experiences of safety management of an airline company. The core research theme of this paper is the interaction mechanisms between governance structure and information concealment：on one hand how governance structure affects the occurrence of information concealment and its prevention，on the other hand how information structure reacts against the function of governance structure. Firstly，with the help of a principal-supervisor-agent model，this paper studies the mechanisms and logics of collusion between supervisor and agent in organization and their impacts on the occurrence of information concealment. Secondly，this paper develops a theoretical framework to illustrate the different efficiencies of three types of information searching based on a model of principal and multi-agents. Finally，this paper discusses how different combinations of information governance and governance strategies affect the modes of bargain in organization.
