This paper presents a method for inferring regional economic structure and prospects from key informant interviews. It describes assumptions which must be made and steps to be taken in moving from individuals to establishment, firm, and industry aggregations. A technique is offered for mapping core relationships among firms and other regional and external actors, and for aggregating firm-centered maps into industrial and regional maps. The mapping technique can be expanded to incorporate historicity and dynamic change.
