In short, "one share is dominant" reflects the high concentration of equity, and the influence of pure equity concentration on corporate governance cannot be said to be absolutely harmful. Equity concentration is also beneficial: equity concentration is conducive to playing the core role of major shareholders in the company and improving the efficiency of the company. Although major shareholders will infringe on the interests of small and medium shareholders in the distribution of corporate interests, on the other hand, we should also see that the interests of major shareholders and small and medium shareholders also have something in common, that is, the interests of shareholders all depend on the company value. If the major shareholders do not exercise the control of the company effectively, it will lead to insider control, and it is difficult to guarantee the interests of the small and medium shareholders.
