本文认为,混合所有制经济有广义、狭义、宏观、中观、微观、以公有制为主体和以私有制为主体之分;混合所有制经济不是与各种不同所有制形式并列的一种独立的新型所有制形式,也不是一种新生的公有制形式,以马克思关于“过渡点”的分析来证明混合所有制经济的公有制性质是不妥的;在混合所有制经济性质的界定上产生诸多分歧的原因在于研究方法的非科学性,消除分歧的关键在于要有一个科学的研究问题的方法。 This paper argues that the mixed-ownership economy is broadly defined, narrowly defined, macroscopical, meso-objective and microeconomic, with public ownership as the main body and private ownership as the main body. The mixed ownership economy is not an independent new form of ownership that is juxtaposed with various forms of ownership, Nor is it a nascent form of public ownership. It is inappropriate to prove the public ownership of a mixed-ownership economy with Marx’s analysis of the “transition point.” The reason for the divergence in the definition of the nature of a mixed-ownership economy lies in the fact that research methods The key to non-scientific and disagreement lies in having a scientific method of researching problems.
