建筑业同工业、农业等一样,也是国民经济中重要的物质生产部门之一。建筑业产品同其它物质生产部门的产品相比,一般说来生产周期更长,体积更大,价值量更高,使用价值发挥作用的时间更久远。然而,在很长的历史时期内,我们总把建筑业只看成是一个消费部门,或者服务部门,而不承认它的物质生产部门的性质,甚至连经济统计也不计算其产值,这不能不说是一种极大的片面性! The construction industry, like industry and agriculture, is also one of the important material production departments in the national economy. Compared with the products of other material production departments, the construction industry products generally have a longer production cycle, a larger volume, a higher value and a longer time for use value. However, in the long historical period, we always regard the construction industry as only a consumer department or a service department, and do not recognize the nature of its material production department. Even economic statistics do not calculate its output value. This cannot be done. Not to mention a great one-sidedness!
