First, the basic economic system in the primary stage of socialism is an organic unity. It includes not only the public ownership economy as the basis of socialist economy, but also other non-socialist ownership economies. Without the dominant position of the public sector of the economy, we cannot guarantee the socialist nature of our society and adhere to the socialist direction and road. Without other ownership economy, it will be divorced from the basic national conditions of contemporary China and the reality of the primary stage. Therefore, other economic components other than public ownership cannot be excluded from the basic economic system because they do not belong to the socialist economy, nor can they be considered as socialist economies because they belong to the basic economic system. The establishment of the socialist basic economic system can organically unify the essential characteristics of socialism with the realistic requirements of the primary stage, which is a major breakthrough and innovation in the theory of socialist ownership, and is more conducive to promoting the development of social productive forces and consolidating and developing the socialist system.
Second, the establishment of the basic economic system in the primary stage of socialism reflects the Party's keeping pace with the times in the theory of ownership. Before the reform and opening up, because the understanding of the basic national conditions surpassed the reality of the primary stage of socialism, it was always believed that the socialist economic system could only be composed of the socialist public economy, and even if the non-public economy was allowed to exist and develop to a certain extent, it could only be a temporary expedient measure. After the reform and opening up, our party's understanding of the non-public sector of the economy has gradually deepened, from calling it "a necessary and beneficial supplement to the public sector of the economy" to emphasizing that "the long-term development of the public sector of the economy and various economic components is a long-term policy", and then the 15th National Congress of the Communist Party of China clearly put forward for the first time that "the public sector is the mainstay and various forms of ownership develop together, which is a basic economic system in the primary stage of socialism in China". This marks our party's understanding of the ownership structure in the primary stage of socialism, which has not only made a major breakthrough and innovation in theory, but also brought China into a new stage of diversified forms of public ownership and common development of various economic sectors in practice.
Third, what kind of ownership structure to establish and what kind of basic economic system to implement can only be judged by whether it conforms to the "three benefits". All forms of ownership that meet the standards of "three benefits" can and should serve the development of socialism.
