Regional development in East Lombok Regency requires the identification of growth centers, hinterland areas, and leading sectors to support more balanced regional development. This study aims to identify districts that function as growth centers and their hinterland areas, analyze the interaction between growth centers and hinterland regions, and identify basic sectors that can be developed as regional leading sectors. This research employed a quantitative approach using Scalogram Analysis with the Guttman Binary method, Gravity Model Analysis, and Location Quotient (LQ) Analysis. The data analyzed included public service facilities, population, inter-regional distance, and Gross Regional Domestic Product (GRDP) data of East Lombok Regency and West Nusa Tenggara Province. The results of the Scalogram Analysis identified four growth centers, namely Masbagik, Selong, Pringgabaya, and Keruak Districts, with a Coefficient of Reproducibility (COR) value of 0.905, indicating that the model was reliable. The Gravity Model Analysis revealed that each growth center has a distinct hinterland area, with Masbagik having the widest hinterland coverage and the strongest regional interaction. Furthermore, the regional interaction pattern was found to be radial and hierarchical. The LQ analysis showed that agriculture, forestry and fisheries, manufacturing industry, and wholesale and retail trade including motor vehicle and motorcycle repair are the region’s basic sectors. Strengthening growth centers through the development of leading sectors and regional linkages is expected to promote more equitable regional development in East Lombok Regency
