Regional Economic Development: An Export Stages Framework
提出了一个长期区域发展过程的通用框架，采用阶段方法，从区域经济封闭开始，后续各阶段由不同经济活动部门主导出口基础，发展取决于出口基础的整体扩张。
A framework is outlined which provides a generalized account of the process of regional development over the long run. The framework utilizes a stages approach, the first stage representing one of regional economic closure. Each subsequent stage involves the regional export base being dominated by a particular sector of economic activity. The sequence of stages (in terms of the sectors dominating the export base) is as follows: primary; secondary (separated into two types); tertiary. Development of the region does not generally depend on passage through the sequence of stages but rather on the overall expansion of its export base.
