Abstract

Regional economic development requires understanding of economic structure and sectoral dynamics to formulate effective and sustainable policies. This study aims to analyze the economic structure and sectoral dynamics of Kotamobagu City by identifying base and non-base sectors and assessing their medium-term sustainability prospects. A descriptive quantitative approach was employed using Gross Regional Domestic Product (GRDP) data of Kotamobagu City and North Sulawesi Province at constant prices for the period 2018–2022. The analysis applied the Location Quotient (LQ) and Dynamic Location Quotient (DLQ) methods. The results indicate that Kotamobagu’s economy is dominated by service sectors, particularly public administration, financial services, social services, and construction, which function as base sectors. However, DLQ analysis reveals that not all base sectors exhibit sustainable growth prospects. Conversely, several non-base sectors demonstrate positive growth dynamics and potential role repositioning. These findings confirm that sectoral advantages are dynamic and cannot be adequately assessed using static approaches alone. This research provides a theoretical contribution to the development of regional economic analysis based on sectoral dynamics and serves as an empirical basis for the formulation of regional economic development strategies.

Abstract

This study aims to identify the relationship between the gravity index and the centrality index on regional hierarchy and to analyze the spatial pattern of Tomohon City. The study was conducted in 44 urban villages and 5 sub-districts using a quantitative spatial approach. The analytical methods included the gravity index, scalogram, Weight Centrality Index, Ordinary Least Square (OLS) regression, and Moran’s I spatial autocorrelation. The variables analyzed consisted of population size, nominal GRDP, geographical distance between regions, and the number of service facilities/functions. The results showed that the gravity index had no significant relationship with regional hierarchy, while the centrality index had a positive and significant relationship with regional hierarchy. These findings indicate that the availability of facilities and service functions plays a greater role in shaping regional hierarchy than spatial interaction factors based on population, GRDP, and geographical distance. Moran’s I values of 0.049687 at the urban village level and 0.049555 at the sub-district level indicate a random spatial pattern without significant spatial autocorrelation. The distribution of facilities and centrality in Tomohon City still reflects spatial inequality. Therefore, improving the distribution of facilities and service functions in areas with low centrality is necessary to support more balanced regional development.
