一些国有企业效益一直不太好，下岗人员大量增加，其中一个主要原因就是企业产品不适应市场的需要，卖不出去，也就是出现了经济学家说的“结构问题”。“结构”的含义很广，包括产业结构、产品结构、技术结构、地区结构等。结构调整是一个不断促使产品与需求相适应的过程，由 The benefits of some state-owned enterprises have not been very good, and a large number of laid-off workers have increased. One of the main reasons is that the products of enterprises do not meet the needs of the market and cannot be sold, which means that there are “structure problems” that economists say. “Structure” has a wide range of meanings, including industrial structure, product structure, technical structure, and regional structure. Structural adjustment is a process that continuously promotes product and demand adaptation.
