Abstract

This study analyzes the contribution and competitiveness of economic sectors in the regencies and cities of West Nusa Tenggara Province (NTB) during 2019–2023 using the Location Quotient (LQ) and Shift Share methods. The research employs a quantitative approach with secondary data from the Central Statistics Agency (BPS), specifically Gross Regional Domestic Product (GRDP) data at constant prices by business field. The results indicate that the primary sector remains the dominant base sector in most regencies such as Lombok Timur, Sumbawa, and Bima, while the secondary sector has not yet become a leading contributor. The tertiary sector shows significant growth in urban areas, particularly in Mataram City and Bima City, were services and trade drive regional economic performance. The Shift Share analysis reveals that Lombok Tengah, Mataram City, and Lombok Barat have positive regional share values (KPPW), indicating higher competitiveness and faster growth, whereas Sumbawa Barat records the lowest value due to limited infrastructure and economic diversification. Overall, the findings demonstrate that the economic structure of NTB remains dominated by the primary sector but is gradually transforming toward a service-oriented economy in urban areas.
