The reform of SOEs is a complex and relatively long-term work, and maintaining the leading position of SOEs in this process is a prerequisite. However, in the process of reform of SOEs, there is a problem of imperfect legal system, leading to the failure of some SOEs to achieve the expected results. Therefore, this paper focuses on analyzing the defects of the existing legal system in the reform of SOEs, and provides advise to improve the system from the aspects of clarifying the status of the main body of property rights, improving the information disclosure mechanism, and establishing the legal system of the executive compensation system, so as to provide reference for promoting the reform of SOEs in the new era.
