张秀生、陈慧女撰文认为,在经济发展过程中,产业结构升级换代是客观规律,正是依靠这种不断更新的机制才能实现经济的可持续发展。然而资源枯竭型城市最初都定位于国家能源、原材料基地进行发展,产业结构严重失衡,升级换代困难重重,经济发展随着资源逐渐枯竭而呈现出后劲不足的趋势。 According to Zhang Xiusheng and Chen Huijian, in the course of economic development, the upgrading of the industrial structure is an objective law. It is by relying on this constantly updated mechanism that economic sustainability can be achieved. However, resource-exhausted cities were all initially located in the national energy and raw material bases for development. The industrial structure was seriously unbalanced. The upgrading and replacement were difficult and the economic development showed a tendency of insufficient staying power as resources gradually dried up.
