What's the best way to describe a sector of economy that is based on selling technologies or anything else, but not on selling raw materials?
Based on the three-sector model, you would say that it is a country whose economy is not based on primary industry. That, however, relies on your audience being familiar with the term. Otherwise, you could just say not based on the production or extraction of raw materials. If you want to be specific, you could say manufacturing-based economy or service economy.
