应当重新学习马克思的经济理论--为纪念马克思逝世120周年而作

战后现代资本主义国家，由于缓解了社会经济矛盾和阶级矛盾而使经济继续增长。我们社会主义国家过去经济发展缓慢的原因在于计划经济体制。这种体制的实质是国家高度垄断而不是有无计划。马克思主义认为垄断排除竞争，必然走向停滞。社会主义市场经济的活力就在于竞争。计划经济体制的失败，并不是科学社会主义理论的错误。马克思主义认为，生产决定消费，消费反过来也决定生产。我国提出扩大内需的方针就是运用消费对生产的重大作用。

the Economic Theory of Marx should Be Newly Learned--in commemoration of Marx's 120th death anniversary

Modern capitalist countries make their economy grow continuously because of remitting social economic contradictions and class contradictions after World War. The cause to slow development of economy in socialist countries before was the system of planned economy, the essence of which is strong government monopoly. Marxism thinks that monopoly removes competition, and the system will end to stop. The vigor of socialist market economy is competition. The failure of the planned economy system is not the fault of scientific socialist theory. And Marxism thinks that production decides consumption, and consumption also decides production. The guiding principle of expanding domestic demand is to use the function of consumption to production.
