Spatial interaction between regions: Study of the East Kalimantan Province, Indonesia

Abstract

City morphology can be formed due to interaction either spatially or the socio-economic community in it. This study aims to determine the classification of fast-growing and growing quadrant areas in East Kalimantan Province, the central growth region and the highest relationship between spatial interactions between the growth centers and the hinterland region. The type of this research is quantitative descriptive research because this research is presented with numbers during 2014-2018. Data used is based on secondary data obtained from the site of the Central Statistics Agency and other related agencies. The analytical tool used is the Klassen Typology and Gravity Index, then processed using Microsoft Excel. The results of the empirical study show that there is one area in East Kalimantan Province that is classified as Quadrant I (Fast Forward and Growing Area), namely East Kutai Regency, and there are dominant seven regions classified in Quadrant III (Rapid Developing Areas), and none occupy Quadrant I (Disadvantaged Region). The area is the center of growth in East Kalimantan Province, namely Berau Regency. Meanwhile, Samarinda City with the highest spatial interaction (attractiveness and potential) with a growth center in Kutai Kartanegara Regency (hierarchy I).
