任何事物的质量都表现为一定的数量,没有数量也就没有质量。量的变化达到一定的界限,必然引起质的变化。社会主义公有制的主体地位,不仅要求社会主义国有经济具有控制国民经济命脉的结构上的优势,而且要求国有经济同集体所有制经济一起使公有制经济在整个国民经济中占有数量上? The quality of everything shows a certain amount, there is no quantity there is no quality. Changes in the amount of a certain limit, will inevitably lead to qualitative changes. The dominant position of socialist public ownership not only requires the socialist state-owned economy to have the structural advantage of controlling the lifeline of the national economy, but also requires that the state-owned economy together with the collective-owned economy make the public-owned economy occupy the entire national economy.
