IDENTIFYING LEADING AND POTENTIAL ECONOMIC SECTORS IN LANGKAT REGENCY: A LOCATION QUOTIENT AND KLASSEN TYPOLOGY APPROACH

Abstract

This study aims to identify leading and potential economic sectors in Langkat Regency using Location Quotient (LQ) and Klassen Typology. A quantitative descriptive approach is applied using sectoral Gross Regional Domestic Product (GRDP) data from 2021 to 2025. LQ is used to determine base sectors, while Klassen Typology classifies sectors based on their growth and contribution relative to North Sumatra Province. The results show that agriculture, mining and quarrying, and electricity and gas are classified as base sectors. However, only the mining and quarrying sector demonstrates relatively high growth and contribution, placing it in the advanced and rapidly growing category. Most other sectors are classified as developing or relatively underdeveloped, indicating an imbalanced economic structure. These findings suggest the need to promote sectoral diversification to support more balanced and sustainable regional economic development.
