Spanish to English Bus/Financial Economics

estructura productiva: aquellas actividades en las cuales recae la actividad productiva de un país y dividido en tres sectores (primario, secundario y terciario).

In English I see that "a classical breakdown of economic activity distinguishes three sectors (primary, secondary and tertiary)" but I don't see ANYTHING akin to "estructura productiva" (except for "product structure", which refers to "the way in which the parts of a product fit together and interact, organized in levels of detail based on structure. A product structure is used to manage changes, testing, and problem resolution for complex products with a large number of interdependent parts and functions" (i.e. it is NOT that)

Any ideas? Thanks in advance!!!
