Briefly describe the concept of corporate governance structure.

A: (1) The narrow corporate governance structure refers to the institutional arrangements related to the functions and structure of the board of directors and the rights of shareholders.

(2) The broad corporate governance structure refers to a set of legal, cultural and institutional arrangements related to corporate control, residual claim and distribution rights. These institutional arrangements determine a series of important issues, such as the company's goals, who controls them in what state, how to control risks and benefits, and how to distribute them among different members of the enterprise.
