建筑业是一个物质生产部门,又是消耗物资最多的部门之一,根据七九年统计资料,基建钢材耗用约占全国总消耗量的24.2％,木材约占26.8％,水泥约占66.5％。因此,重视提高建筑业物资使用效益,对发展我国国民经济,实现本世纪末工农业总产值翻两番,具有特别重要的意义。 The construction industry is a material production department, and it is also one of the sectors that consume the most materials. According to the statistical data in 1979, the consumption of infrastructure steel accounted for approximately 24.2% of the country’s total consumption, timber accounts for approximately 26.8%, and cement accounts for approximately 66.5%. . Therefore, it is of special significance to attach importance to improving the efficiency of the use of materials in the construction industry, to quadruple the development of China’s national economy and to achieve a total output value of industry and agriculture at the end of this century.
