The study was using secondary data of time series from 2015 to 2019. Location Quotient (LQ) was used for localization and specialization analysis, as well as for basic service ratio (BSR) and regional multiplier (RM) analysis. The results showed that the region of the gambir commodity base based on the production indicator consists of Salak subdistrict, Sitellu Tali Urung Jehe sub-district, Pergetteng Getteng Sengkut sub-district, and Tinada sub-district. The gambir community forest is not concentrated in one region but is scattered in several sub-districts. Pakpak Bharat District also does not specialize in gambir community forest. Gambir commodities can support plantation activities and the regional economy in Pakpak Bharat District. The existence of the gambir community forest supports economic activity in the form of the multiplier effect generated for the sub-districts in Pakpak Bharat District.
