The paper reviews three important theories in corporate governance, different theories using different terminology, and views corporate governance from different perspective. Some articles are used to support these theories in this paper. From the Cadbury Report in 1992, we can get the information that corporate governance is the system by which companies are directed and controlled, which involves a set of relationship between a company’s management, its board, its shareholders and other stakeholders, and the objectives for which the corporation is governed.

These three theories play significant roles in understanding the corporate governance and helpful for people to know how the corporate governance developed.
