当今,科学技术已成为经济发展的巨大推动力。从煤炭工业发展来看,在五十年代初期,以先进的生产技术和设备,改变了解放前的技术落后面貌,使煤炭产量大幅度地提高,到五十年代末达到了建国初前的七倍。但后来由于“左”的错误影响,忽视了科学技术的作用,使生产出现了马鞍形并停滞不前。特别是十年动乱,科学技术残遭破坏,使生产频于崩溃的边 Today, science and technology have become a huge driver of economic development. From the perspective of the development of the coal industry, in the early 1950s, with advanced production technologies and equipment, the backwardness of technology before the liberation was changed so that the coal output was greatly increased. By the late 1950s, it reached the level of seven Times However, due to the wrong influence of “the left”, the role of science and technology was ignored and the saddle shape of production appeared to be stagnant. In particular, during the ten years of turmoil, science and technology were destroyed and the production was frequently collapsing
