The data used in this study uses secondary data taken from the website of the Central Bureau of Statistics. The variables used are gross regional domestic product of 34 provinces in Indonesia (Y, in billion rupiah), labor force participation rate (X1, in %), foreign investment (X2, in million dollars), open unemployment rate (X3, in %) and human development index (X4, in %). Data were analyzed using GWR with adaptive gaussian kernel weighting function. GRDP in all provinces on the island of Sumatra (11 provinces), DKI Jakarta province, Banten province, and West Kalimantan province are influenced by foreign investment (X₂) and human development index (X₄). Meanwhile, GRDP in the other 19 provinces is only influenced by foreign investment (X₂). GWR model with adaptive gaussian kernel weighting function is formed differently for each province in Indonesia.</p> <p><strong>Keywords</strong>: Adaptive gaussian kernel; GWR;<em> g</em>ross regional domestic product</p> Frangly Elviano Tangka Djoni Hatidja Winsy Ch.D Weku Copyright (c) 2024 Frangly Elviano Tangka, Djoni Hatidja, Winsy Ch.D Weku https://creativecommons.org/licenses/by-nc/4.0 2024-06-11 2024-06-11 110 119 10.35799/jis.v24i2.50366
