【摘要】 公有制产权具有明显的不确定性 ,说公有制一定比私有制优越缺少科学根据 .马克思主义承认公有制的优越性是以公有制在一定条件下更有利于发展生产力为前提条件的 .公有制产权不能必然带来高效率和生产力的发展 ,已经为前社会主义国家和现实社会主义国家公有制经济的低效率所证实 .就现代企业制度的演变和发展看 ,企业产权的公有还是私有并非企业存在与发展的决定性因素 .公有制与私有制孰优孰劣的问题 ,从经济学的角度看 ,是一个规范经济学的问题 (或者说是一个伦理经济学的问题 ) ,而不是一个实证经济学的问题 .从规范经济学的角度看 ,说公有制必定优于私有制缺少科学根据 ;从实证经济学的角度看 ,公有制往往导致低效率 ,这已是不争的事实 .更多还原

Marxist confessed public property had superiority that it is more favorable expand productivity in particular condition. The public property must not bring high efficiency and productivity development that confirm with low efficiency of public ownership economy in former socialism state and reality socialism state. The modern times enterprise institution evolve and expand speak, the property right of enterprise publicly-owned or privately owned is not conclusive factor with enterprise exist and development. The issue of who is best publicly-owned or privately owned is a issue of normative economics(or a issue of ethical economics), is not a issue of positive economics. In normative economics think the public-owned enterprise excellent then privately owned is not scientific basis; in positive economics, the public-owned frequently cause to low efficiency that is a no debate.更多还原
