Abstract

The primary component of aggregate demand, which represents both the stability of the local economy and the degree of community wellbeing, is household consumption. The purpose of this study is to examine how household spending in North Sumatra Province was affected by the Economic Growth Rate (LPE), inflation, and unemployment between 2001 and 2021. To assess both short-term and long-term correlations between variables, secondary data is analyzed using the Error Correction Model (ECM). According to the study's findings, long-term household consumption is positively and significantly impacted by LPE, indicating that economic expansion can raise people's purchasing power. In the meanwhile, both in the short and long term, unemployment and inflation have a detrimental but insignificant impact. A robust adjustment mechanism to the long-term balance is indicated by the significant correction coefficient of −0.969383. Therefore, it can be said that household spending in North Sumatra is mostly influenced by economic growth, with inflation and unemployment having comparatively little effect. The results of this research have implications for the importance of inclusive economic growth policies to strengthen household consumption, in line with achieving the Sustainable Development Goals (SDGs), especially Goal 1 (No Poverty) and Goal 8 (Decent Work and Economic Growth).

Abstract

Human Development Index (HDI), Minimum Wage, Poverty, North Sumatra, Multiple Linear Regression. Poverty is one of the main problems in economic development that is still faced by various regions in Indonesia, including North Sumatra Province. This study aims to analyze the effect of the Human Development Index (HDI) and the Provincial Minimum Wage (PMW) on the Percentage of Poor Population in North Sumatra during the period 2018-2025. This research uses a quantitative approach by utilizing secondary data obtained from official publications of the Central Statistics Agency. The analytical method used is multiple linear regression with the assistance of SPSS version 25 software. Before conducting regression analysis, the data were first tested through classical assumption tests including normality, multicollinearity, heteroscedasticity, and autocorrelation tests. The results show that partially the Human Development Index has a negative and significant effect on the percentage of poor population with a t-value of -3.174 and a significance level of 0.025. The Provincial Minimum Wage also has a negative and significant effect on the percentage of poor population with a t-value of -10.178 and a significance level of 0.000. Simultaneously, the Human Development Index and Provincial Minimum Wage have a significant effect on the percentage of poor population with an F-value of 62.130. The coefficient of determination value of 0.961 indicates that 96.1% of the variation in the percentage of poor population can be explained by these two variables. These findings indicate that improving the quality of human development and implementing appropriate minimum wage policies can contribute to reducing poverty levels in North Sumatra.
