Analysis of Location Quotient, Shift-Share Analysis, and Klassen Typology in Determining Leading Regional Products in Sukabumi Regency

Regional economic development requires the identification of leading sectors as a foundation for formulating effective, inclusive, and sustainable development policies. Sukabumi Regency has a diverse economic structure with a dominance of primary sectors; however, a comprehensive study integrating sectoral base analysis, sectoral competitiveness assessment, and the determination of leading regional products is still required. This study aims to analyze the leading economic sectors of Sukabumi Regency using the Location Quotient (LQ), Shift-Share Analysis (SSA), and Klassen Typology approaches. This study employs a descriptive quantitative approach using secondary data consisting of the Gross Regional Domestic Product (GRDP) of Sukabumi Regency and West Java Province for the period 2021–2025, as well as production data of agricultural, plantation, livestock, forestry, and fisheries commodities published by the Central Statistics Agency. The results of the LQ calculation, sectoral competitiveness analysis based on SSA, integration through Klassen Typology, and the formulation of Leading Regional Products (LRPs) based on regional potential and the criteria stipulated in the Regulation of the Minister of Home Affairs Number 9 of 2014 indicate that the leading sector of Sukabumi Regency is the Agriculture, Forestry, and Fisheries sector. Based on the synthesis of sectoral analysis results, commodity potential, value-added opportunities, regional distribution, downstream processing potential, environmental sustainability, and the provisions of Regulation of the Minister of Home Affairs Number 9 of 2014, ten Leading Regional Products of Sukabumi Regency are recommended: banana, coconut, durian, marine fisheries (tuna–skipjack–mackerel tuna), Sukabumi coffee, cayenne pepper, tomato, mangosteen, papaya, and bamboo crafts. The findings of this study are expected to provide a foundation for developing local economic development policies based on regional potential.
