Abstract: By analyzing the control structure of listed companies in China, this paper points out that the control structure of listed companies presents a high concentration to controlling shareholders, which weakens the corporate governance mechanism of "three powers" separation and checks and balances. As a result, the motivation of major shareholders to pursue the gains of their control to the detriment of other shareholders and listed companies is strengthened, and corporate behavior is distorted. Therefore, responding to the restructure of corporate authority to optimize the company's control structure is the key to improving the corporate governance structure.
