The Influence of GDP per Capita, Income Inequality, and Population on CO2 Emission (Environmental Kuznet Curve Analysis in Indonesia)

Abstract

This study aims to prove the environmental kuznet curve (EKC) hypothesis in Indonesia and the effect of GDP per capita, income inequality, and population on CO2 emissions. This research uses a descriptive quantitative method. The data used is the time series from 1990-2021. The data analysis method used is the error correction model (ECM) to see the effect of the independent variables on the dependent variable in the short term and long term. The results of this study indicate that the EKC hypothesis is not proven in Indonesia either in the short term or in the long term. GDP per capita has a significant positive effect on CO2 emissions both in the short term and long term. Income inequality has no significant positive effect on CO2 emissions in the short term and no significant negative effect in the long term. The population has no significant negative effect on CO2 emissions in the short term and has a significant positive effect in the long term.

Temporal Dynamics of Countries' Journey to Cluster-Specific GDP per Capita: A Comprehensive Survival Study

“…The examination of economic development trajectories, particularly in terms of GDP per capita, extends beyond a mere quantitative evaluation of a country's prosperity. It necessitates a nuanced understanding of the intricate interplay among various socioeconomic factors over time (Yunita et al, 2023). Our scholarly pursuit aims to contribute to this discourse by emphasizing the temporal dimension, transcending traditional static analyses, and providing a more comprehensive comprehension of the developmental processes at play.…”

Analysing Economic Convergence Across the America: A Survival Analysis Approach to Gross Domestic Product Per Capita Trajectories

“…With a focus on a time-centric lens, the study contributes not only to theoretical advancements in economic literature but also to the formulation of more effective policies aimed at expediting and sustaining economic growth. The introduction of models commonly used to study GDP, such as the neoclassical growth model, the Keynesian model, the Solow growth model, and the Harrod-Domar model, lays the foundation for a comprehensive exploration (Dutta & Mishra, 2023;Nolan et al, 2019;Yunita et al, 2023).…”
