发展和壮大国有经济,搞好国有大中型企业,是由我国社会主义的基本制度决定的,我们所要建立的社会主义市场经济体制,是以公有制为主体、多种经济成份共同发展的市场经济体制。而公有制的主体地位,一是体现在国家和集体所有的资产在社会总资产中占优势;二是国有经济控制国民经济的基 The development and expansion of the state-owned economy and the improvement of large and medium-sized state-owned enterprises are determined by the basic system of socialism in our country. The socialist market economy system we are to establish is a market economy system in which the public ownership system is the main body and various economic components are developed together. . The dominant position of public ownership, first, is that the assets owned by the state and the collective enjoy an advantage in the total social assets; second, the state-owned economy controls the basis of the national economy.
