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.
