<![CDATA[ This study aims to analyze the base sectors, structural shifts of the regional economy, leading sectors, and the influence of leading sectors on economic growth in Trenggalek Regency for the period 2015-2024. The methods employed include Location Quotient (LQ), Shift Share, Overlay analysis, and multiple linear regression using Gross Regional Domestic Product (GRDP) data at constant prices. The results show nine base sectors, with Agriculture, Forestry, and Fisheries recording the highest average LQ value of 2.29. The Shift Share analysis reveals that all economic sectors posted positive Proportional Shift (PS) values, indicating an ongoing structural transformation of the regional economy from the primary sector toward the secondary and tertiary sectors. The Overlay analysis identifies six leading sectors: Mining and Quarrying, Real Estate, Business Services, Government Administration and Defense, Education Services, and Health Services and Social Activities. Regression results indicate that the Financial Services and Insurance sector and the Other Services sector each exert a positive and statistically significant effect on economic growth at the five-percent significance level, while the Agriculture, Forestry, and Fisheries sector does not demonstrate a significant effect. Simultaneously, the three independent variables explain 95.97 percent of the variation in economic growth in Trenggalek Regency, confirming the strategic role of leading sectors in driving regional economic development.]]>
