ICT and Carbon intensity

This study investigates the effect of information and communication technology (ICT) and internet use on carbon intensity across 100 countries, utilizing an extended stochastic impacts by regression on STIRPAT model with the countries panel data from 2000 to 2021 years. Employing quantile regression analysis, the findings reveal three key insights. First, ICT adoption plays a significant role in reducing carbon intensity. Second, the use of renewable energy has a negative effect on carbon intensity. Third, internet use has a negative effect on carbon intensity. The analysis also highlights the positive contributions of industrial structure and population growth to carbon intensity, underscoring the need for countries to prioritize the expansion of renewable energy and strategic efforts to improve industrial structure are essential for mitigating carbon intensity and achieving long-term sustainability goals.本研究采用2000至2021年的跨国面板数据，运用拓展的STIRPAT（Stochastic Impacts by Regression on Population, Affluence, and Technology）模型，探究信息与通信技术（ICT）及互联网使用对全球100个国家碳强度的影响。通过分位数回归分析，本研究得到三项核心结论：其一，信息与通信技术的普及对降低碳强度具有显著作用；其二，可再生能源的使用对碳强度存在负向影响；其三，互联网使用同样对碳强度具有负向影响。此外，本分析还指出产业结构与人口增长对碳强度具有正向推动作用，这凸显出各国需优先扩大可再生能源规模，并通过战略性举措优化产业结构，这对于缓解碳强度、实现长期可持续发展目标至关重要。
