Pemodelan Investasi Derah di Indonesia dengan Pendekatan Regresi Nonliner

Abstract

Investmentis a very important activity because it supportsproduksi, so that investment can boost pertumbuhan economy. Indonesia is one of the countries with a low level of investment. In general, the picture of the amount of regional investment in Indonesia according to the data on the number of PMDN and FDI recorded by BPS, the amount of capital invested in Indonesia is developing. The province with the highest average number of FDI is West Java which reaches Rp. 74912.32 billion rupiah per year. Meanwhile, West Sulawesi is the province with the lowest average number of FDI which only reaches Rp. 508.7598 billion rupiah per year. Likewise, East Java as the province with the highest number of PMDN, with an average domestic capital of Rp.45164.5 billion per year. Meanwhile, Maluku province with the lowest PMDN with an average domestic capital only reaches Rp.367.04 billion per year. This shows that the range of the number of FDI andPMDN in Indonesia has increased, but the distribution of the amount of capital invested has not been evenly distributed. Togeta nonlinear regression model on regional investment in Indonesia, thenyoucan model using all predictor variables and significant variables. With the results of modeling as followsBased on the results of parameter estimation, a nonlinear regression model using significant variables is the best nonlinear regression model, because it produces a smaller MSE value
