This study aims to map the most potential vegetables to be developed in West Sumatra Province.The Location Quotient (LQ) method is employed to identify leading and non-leading commodities,while the Shift Share Analysis (SSA) is used to analyze structural changes and the competitivenessof the commodities. The study utilizes secondary data in the form of vegetable sub-sectorhorticultural production data by regency/city over a six-year period (2017–2022). The results showthat large chili is the leading vegetable commodity in West Sumatra, with an LQ value greater than1 across 17 regencies/cities. Conversely, garlic is categorized as a non-leading commodity, with anLQ > 1 found in only one regency. Nevertheless, garlic is identified as the most progressivecommodity based on the highest net shift value. Net growth of vegetable sub-sector commoditieswas identified in 10 out of 18 regencies/cities, with Solok Regency contributing the most. In termsof individual commodities, cabbage recorded the highest net growth, while chayote experienced thelowest. The resulting commodity mapping can serve as a basis for local government in formulatingspatial and sustainable development policies, as well as a strategic reference for businesses andinvestors in directing horticultural investments in West Sumatra.
