由于建筑市场竞争的加剧,利润相对减少,施工企业往往靠扩大经营规模来维持期望的利润。但是,随着承揽任务的增多,市场规模的扩大,施工企业自有施工力量不足的矛盾便日渐突出,于是几乎所有的施工企业都或多或少地利用外部施工力量,对承揽的工程进行以分包或租赁设备或招收劳务的形式来解决这一矛盾。但多数企业在分包管理中的效益流失严重,质量、安全难以保障,从而给施工企业带来难以面对和承受的损 Due to intensified competition in the construction market, profits are relatively reduced, construction companies often rely on expanding the scale of operations to maintain the desired profit.
