In view of the basic principles of Marxism and the historical context of social and economic development, the slow-growth law of capitalist private ownership accords with objective reality. From the perspective of theoretical logic, the mechanism of this law is based on three main paths: first, the general law of capitalist accumulation inevitably leads to underconsumption; second, the law that private enterprises do invest until they have reached their expected profits or the law of declining average profit margins inevitably leads to underinvestment in the real economy; and, third, the profit-seeking nature of capital and the law of average profit margins inevitably lead to industrial imbalance. From the point of view of realistic logic, the results of long-term growth and negative growth of capitalism since the 20th century have confirmed the objective existence of the theorem of “slow growth of capitalist private ownership” , indicating that private ownership has a restraining effect on economic growth.
