This study has been conducted to examine the impact of trade, economic growth, and renewable energy on environmental degradation in G7 countries. The data consist of the years 1991-2016. We employed the panel unit root test and co-integration test, along with cross-sectional dependence and cross-sectionally augmented IPS unit root test by Pesaran (J Appl Econ 22:265-312, 2007). We also employed dynamic ordinary least squares, fully modified ordinary least squares, and fixed effect ordinary least squares regression. The result concluded that all the variables are co-integrated in the long run and all the variables create a significant effect on CO emission. This study implies that economic growth and trade increases the CO emission in the long run whereas the renewable energy consumption reduces the CO emission in the long run. The result also provides support for the Environmental Kuznets curve hypothesis in G7 countries.
本研究旨在考察 G7 国家贸易、经济增长和可再生能源对环境恶化的影响。数据涵盖了 1991 年至 2016 年。我们采用了面板单位根检验和协整检验，以及 Pesaran（J Appl Econ 22:265-312, 2007）提出的横截面相关性和横截面增强 IPS 单位根检验。我们还采用了动态普通最小二乘法、全修正普通最小二乘法和固定效应普通最小二乘法回归。结果表明，所有变量在长期内都是协整的，所有变量对 CO 排放都有显著影响。本研究表明，经济增长和贸易会在长期内增加 CO 排放，而可再生能源消费会在长期内减少 CO 排放。结果还为 G7 国家的环境库兹涅茨曲线假说提供了支持。
