The export stages framework regards mineral exploitation as a primary rather than a secondary activity, and divides the secondary sector into its processing and fabricative parts, whereas the development stages theory treats mineral exploitation as a secondary-sector activity, and deals mainly with the processing-manufacturing end of the secondary sector (the assignment of activities to particular sectors will be considered later).
The progression from Stage III to Stage IV witnesses fabricative manufacturing taking over from processing manufacturing as the DXS.
On the supply side, a region's lack of competitiveness in fabricative manufacturing during Stage IV would act as a serious push factor.
13) Third, a distinction is made in the secondary sector between processing manufacturing and fabricative manufacturing.
A substantial component of export base production would consist of primary-sector as well as secondary-sector activity (both processing and fabricative manufacturing) in most, if not all, regions, although none of these sectors would be dominant.
