Dynamic relationships between environment-related technologies, agricultural value added, transport infrastructure and environmental emissions in the five most populous countries by Yinuo Wang, Arshad Ali, Zhaojie Chen

“…Per capita GDP extensively promotes per capita carbon dioxide emissions, while per capita GDP2 substantially reduces per capita carbon dioxide emissions in the long term rather than the short term, thus authenticating the inverted U-shaped EKC hypothesis for the top five countries with the highest population density. The moderating effect of environment-related technologies shows that the application of environment-related technologies in both transportation and agriculture can alleviate environmental pollution. …”
