Abstract:  To build a highlevel socialist market economy system，we must adhere to the two “unwavering” principles Because China is developing its market economy under the basic socialist economic system，developing and strengthening stateowned economy helps to leverage the advantages of the socialist system and better leverage the role of the government To play the decisive role of the market in resource allocation，it is necessary to vigorously develop the private economy The key to building a socialist market economy system with coordinated development between stateowned economy and private economy is to optimize the layout of the stateowned economy and allow them to leverage their respective advantages in different fields，promoting each other and developing together The key to substantively promoting the optimization of the layout of the stateowned economy is to establish the standard of “optimization”，so as to establish an implementation plan based on this standard that includes where the stateowned economy should go and where it shouldnt go This article advocates to handle the relationship between the stateowned economy and the private economy based on the principle of classified reform，and achieve the optimization of the layout of the stateowned economy
