Abstract

This study aims to analyze the influence of private investment, mobile phone ownership, and per capita expenditure on Gross Regional Domestic Product at Constant Prices (GRDP) in 34 provinces of Indonesia during the period 2019-2024. The transformation of Indonesia's economy in the digital era has created complex dynamics where traditional factors such as investment and consumption interact with information technology adoption to drive regional economic growth. This research employs a quantitative approach with panel data regression analysis using the Random Effect Model (REM). Data were obtained from the Central Bureau of Statistics (BPS) and the Investment Coordinating Board (BKPM) across 204 observations (34 provinces over 6 years). The results indicate that private investment has a positive and significant effect on GRDP, with a coefficient of 0.289023 and p-value of 0.0306. Per capita expenditure has a positive and significant effect as the most dominant factor with a coefficient of 7.295115 and p-value of 0.0116. However, mobile phone ownership has a negative and significant effect on GRDP with a coefficient of -526.5233 and p-value of 0.0495. The coefficient of determination (Adjusted R²) of 0.5574 indicates that 55.74% of the variation in GRDP can be explained by the three independent variables, while the remaining 44.26% is explained by other variables outside the research model. These findings provide important implications for the government in formulating investment policies, digital literacy improvement, and household consumption stimulus to drive inclusive and sustainable regional economic growth in Indonesia.

Abstract

This study aims to analyze the influence of Private Investment (a combination of Domestic Direct Investment and Foreign Direct Investment) and Real Per Capita Expenditure on Gross Regional Domestic Product at Constant Prices (GRDP-CP) across 34 provinces in Indonesia. Employing a quantitative approach using secondary data from Statistics Indonesia (BPS) for the 2019–2024 period, the model was estimated via panel data regression using the Panel Estimated Generalized Least Squares (EGLS) method with Cross-section Random Effects. Partial analysis results indicate that the Private Investment variable has a positive and significant effect on GRDP-CP. Similarly, Real Per Capita Expenditure was found to make a highly significant positive contribution to boosting regional economic output. Simultaneously, these two independent variables explain 49% of the variation in regional GRDP-CP movements. These findings offer policy implications for local governments to continue optimizing the non-government investment climate inclusively and maintaining public purchasing power stability to accelerate sustainable regional economic growth.
