| During the past ten years, the number and size of listed companies in China had developed rapidly, but the overall profitability is low. The root reasons for such a bad state are that: firstly, because of the economic transition, the development environment of listed companies is constantly changing; Secondly, most listed companies have irrational structures, and the irrational structures lead to poor company performance. With the development of modern corporate system, the ownership structures are changing.
