业内一种观点片面认为,建筑工业化水平高低主要取决于预制率高低,导致全国上马了大批的预制构件厂。而在实施层面,目前在一线或二线城市投资一个现代化的预制构件厂,至少1亿元以上。在建筑工业化发展的初期,由于理念、政策、市场、成本、全产业链配套要素,如建筑工业化设计、生产、吊装、施工等制约,往往缺乏有效需求。在一些地方已经出现了构件厂设计产能是实际有效需求5倍以上的情况,已经造成了新的产能过剩。 One industry view is one-sided that the level of industrialization depends mainly on the level of prefabrication, leading to the country launched a large number of prefabricated plant. At the implementation level, at present, a modern prefabricated component plant is invested in tier one or tier two cities at least 100 million yuan. In the initial stage of the industrialization of buildings, due to the restriction of concept, policy, market, cost and supporting elements of the whole industry chain, such as industrialized design, production, lifting and construction, the effective demand is often lacking. In some places, the design capacity of component factories has been more than five times the actual effective demand, which has caused a new overcapacity.
