The purpose of this study is to examine whether the manufacturing sector, especially the large and medium scale sectors, is a basic sector or not in the Bogor Regency area in terms of the aspect of expanding employment opportunities. The quantitative methods used in this study are (1) Location Quotient (LQ) analysis, (2) labor surplus analysis, (3) multiplier coefficient, (4) specialization quotient, (5) localization quotient. The result shows that the manufacturing sector is the basic sector based on income indicators. However, this sector is not a basic sector based on labor indicators. This shows that the manufacturing sector plays less of a role in expanding employment than other sectors. However, several manufacturing industry sub-sectors are basic sub-sectors. These sub-sectors are the food, beverage and tobacco sub-sector, the textile, apparel and leather sub-sector, the wood, bamboo, rattan, grass and similar sub-sectors including household furniture, paper, paper goods, printing and publishing sub-sectors of chemicals and goods from chemical, petroleum, coal, rubber and non-metallic minerals sub-sectors.
