【摘要】In this article, we pointed out that the hard point of big SOE's corporation governance in China is the construction of manager selecting mechanism, according to the theory of corporation governance and China's practice situation. The laws and policies of representative of client SOE assets, the interest and duties of client are under construction. The ways of how to treat the client's issues are not very clear. The current manager selecting mechanism still cannot solve the problem of “cheap voting”. We also analyzed its negative influence on SOE performance.Finally, based upon the above analysis, we gave some reform suggestions to overcome the hard point both from the manager selecting mechanism side and the big SOE management side.
