The Identification of Economic Base Industries, with an Application to the Newfoundland Fishing Industry
提出识别经济基础产业的理论和方法，并应用于纽芬兰渔业，发现其经济影响远超增加值所显示的水平。
The contribution of an industry to GDP is typically measured by its value added. However, casual observation suggests that some industries play a greater role in overall economic activity than this measure indicates. Observations of this kind have in particular been applied to resource industries and have given rise to the concept of the economic base. Unfortunately, empirical and econometric verification of the concept of a base industry has been limited. This paper outlines a theory of base industries, develops a methodology for identifying economic base industries and measuring their impact, and applies this methodology to the fishing industry of Newfoundland. <i></i>
