Using a quantitative approach and multiple linear regression. The results of the study indicate that simultaneously the variables PMDN, the number of industrial sectors, and the population have a significant positive effect on the GRDP of Sidoarjo Regency. Together, these three variables have a significant impact on GRDP, but individually only the number of industrial sectors and the population have a significant impact on GRDP.
