In the 1990s, the emergence of asset restructuring makes connected transactions more and more important. However, with the continuous deepening of the reform of state-owned enterprises, there is a very close relationship between the listed companies that have not been completely restructured and the holding subsidiaries. Unfair related party transactions occur frequently, which leads to the failure of effective allocation of market resources, and also makes the development of state-owned enterprises face severe challenges. The rights and interests of investors and small and medium shareholders are infringed. In order to restrain unfair connected transactions, it is obviously not enough to use only accounting standards, audit supervision and other external supervision means. At the same time, by improving the internal control system, we can better realize the management and supervision of the enterprise's own related transactions.
