Innovation and renewable energy consumption have a positive impact on environmental quality, but innovation represented by patent applications from nonresidents increases carbon dioxide emission. Renewable energy consumption and international trade contribute to improved environmental quality, while foreign direct investment and economic growth increase emissions and lead to environmental degradation. The quadratic term of economic growth confirms the validity of the environmental Kuznets curve in the Belt and Road Initiative countries. These findings have significant policy implications for the sample countries in terms of technological innovation and renewable energy consumption for enriching environmental quality.
Attaining sustainable economic growth has become an important concern for most countries. Countries are accelerating economic growth; however, an increase in economic activities through production raises energy demand and thus leads to high carbon emissions. Innovations might be useful to enhance energy efficiency and acquire renewable energy sources to be used for production and achieve sustainable growth. This study examines the effect of innovation, renewable energy consumption, and economic growth on carbon dioxide emission in the belt and road initiative countries from 1979 to 2019. The study uses OLS, fixed effect, and generalized method of moments for analysis where the results indicate that innovation indicators significantly improve environmental quality; however, innovation proxy by patent application nonresidents increases carbon dioxide emission. The study also found that renewable energy consumption and international trade significantly raise environmental quality, while foreign direct investment and economic growth raise emissions and lead to environmental degradation. The quadratic term of economic growth confirms the validity of the environmental Kuznets curve in the belt and road initiative countries. The findings of this research have significant policy implications for the sample countries regarding environmental quality enrichment through improvement in technological innovation and acquiring renewable energy consumption.
