In the decentralized management system, when we view the enterprise as a whole, there exists information asymmetry in the business, and the transfer pricing system works as a information transmission mechanism, so the error in the transfer pricing will necessarily lead to erroneous in the information transmission process and cause some problems in the internal management of the enterprise which is specified as that divisions make false report about their private information and the inconsistency lies between the target of the business as a whole and the divisions
從企業整體來看，在分權經營的管理模式下，企業內部存在著信息不對稱，同時內部轉移定價機制是作為一種信號傳遞機制而存在的，因此制定錯誤的轉移價格必然導致企業內部信息的錯誤傳遞，這無疑會造成企業內部出現分權部門謊報私有信息，帶來企業整體和分權部門的目標不一致等問題。
