长期经济增长, 需要民营经济长期存在。在今后生产力发展的相当一段时期中, 公有制经济都不宜大范围长时期单独存在, 都需要大量民营经济与之形成基于所有制中性的长期竞争合作关系。因为公有制经济长期单独存在并不是经济持续高质量增长的唯一动力。然而学界仍对民营经济是否应在长期存在这一问题存在分歧。本文对“消灭私有制”这一论调溯本求源, 阐明私有制消灭论都依赖于马克思对私有制四大趋势的论断, 本文一一指出四大趋势与当今经济事实的不符, 并不存在如马克思描述般导致民营经济将灭亡的内因, 私有制和社会平等、缩小贫富差距是可以共存的。反观单独存在的公有制经济, 由于人性的自利、认知的有限性和资源的稀缺性而不能长期地高质量发展。私有制批判者认为私有制会导致贫富极化, 资本无序扩张等诸多问题。即便出现了社会贫富差距, 也不必非要通过消除民营经济来解决问题, 完全可以通过其他制度和政策而得以缓解。

Long-term economic growth requires the long-term presence of the private economy. For a considerable period of time in the future development of productive forces, the public ownership economy is not suitable for the public ownership economy to exist alone on a wide scale for a long period of time, and it needs a large number of private economies to form. a long-term competitive and cooperative relationship with it based on the neutrality of ownership. Because the long-term existence of the public ownership economy alone is not the only driving force for sustained high-quality economic growth. However, there are still differences in academic circles on whether the private economy should exist in the long term. This paper traces the origin of the argument of "eliminating private ownership", and clarifies that the theory of eliminating private ownership relies on Marx's assertion of the four major trends of private ownership. This paper points out one by one that each of the four major trends is inconsistent with today's economic facts, and there is no internal cause that will lead to the demise of the private economy, as described by Marx. Private ownership and social equality and narrowing the gap between the rich and the poor can co-exist. On the contrary, the public ownership economy, which exists on its own, can’t develop with high quality for a long time due to human self-interest, cognitive limitations and scarcity of resources. Critics of private ownership argue that private ownership leads to polarization of the rich and the poor, uncontrolled expansion of capital and many other problems. Even if there is a social gap between the rich and the poor, it is not necessary to solve the problem by eliminating the private economy, but can be alleviated through other systems and policies.
