The momentum of initial ownership reform of China results from two appeals such as “stability” and “development” and chooses the reform path of incremental reform first and then stock reform under the leadership of “helping government”. Currently, the high profit of China’s state-owned economy mainly emanates from super-profit of monopoly, but the production efficiency of the state-owned economy is still lower than non-state-owned economy. Improper intervention from Chinese government results in excessive monopoly of state-owned economy in some industries and further causes the distortion of market competition and the loss of national economy. Thus, the transition progress of China’s ownership structure is not ended, the ownership structure regulation should be further deepened, i.e. weaken and eliminate the monopoly of state-owned economy in all nonnatural monopoly industry and strategic industry. To deepen ownership structure regulation, the importance must be attached to stock regulation, and the power-renting issue of the Chinese who are vested interests in the reform must be solved, however, the momentum for China to deepen ownership reform is not enough and Chinese Government should use political system reform and legal construction to cohere the new momentum for economic system reform..
