This thesis synthesizes the economic theory of New Institutionalism and State theory to argue that the Mainland China still exerts its political rule of being "unwilling to change." From the limited sphere of "carrying out the diversity within a state-owned system" to its persistent and high-sounding framework of "Four Insistences," infact Mainland China engages in a partial amendment of "estate correction," a correction that fails to achieve the goal of a total reform in the state-owned enterprise sector. A reformation with a premise of being unable to alter the state-owned system will lead to an ineffective reform of property rights and will be destined to fail. This paper also attempts to prove that the reformative mode of a "gradual- increase" is the theoretical generalization of this "low-effective reform." Moreover, this thesis will present four types of "State Barriers" - generalized macro control, absence of property rights, deadlocked negotiations, and political soft constraints - to reason that the "legitimate violent potential" as one of the state violent potentials turns out to be the greatest obstacle to the reformation of the stated-owned enterprise.
