As a tool of information transmission, the media, by summarizing and disseminating information, makes the influence of a wide range of interest groups on corporate governance realized and strengthened, and the role of social norms on corporate governance more fully displayed. The high popularity of media and the resulting governance effect play an extremely important role in protecting investors' interests, ensuring market fairness, efficiency and transparency, reducing systematic risks and establishing a sound capital market supervision system.Reputation is the evaluation of the whole and comprehensive quality of an individual or an object by the public. As the name implies, it is the reputation and reputation of a person or an object, showing the social status and degree of respect of a person or an object. Fama first introduced the concept of reputation into the economic field in the late 1970s. He pointed out that reputation theory played a positive role in the competition in the manager market, and managers would work harder for the consideration of external market pressure and development prospect. In the manager market competition mechanism, the manager's good reputation can bring him better development platform and more abundant remuneration, while the company's business performance and development level play a major role in determining the manager's reputation. In the pursuit of a better reputation, managers will work harder to improve business performance on the one hand, and will automatically restrain violations on the other hand. Subsequently, scholars studied on the basis of Fama research and pointed out that the manager's reputation had an incentive effect on the manager, although the specific incentive method of reputation was not specified in the contract. However, it is found that a good professional reputation helps to improve the ability of managers to bargain in the market and prove their value and performance through the enterprise.

Second, media supervision of the shortcomings of corporate governance.Effect of media supervision on the corporate governance of early research focused on the case study, the most classic case is belong to shareholder activists Monks in 1992 in the Wall Street journal, in the form of advertising denounced the low efficiency of management by the board of directors of the sears roebuck events, the ads, sears the board of directors of the company to take active measures to improve, for almost all adopted Suggestions for improvement are put forward by the Monks.
