本研究探讨了如何增加信息和通信技术在撒哈拉以南非洲（SSA）的渗透可以通过减少二氧化碳排放量对环境的可持续性作出贡献。经验证据基于2000-2012年期间的广义矩法和44个国家。衡量信通技术的标准是互联网渗透率和移动的电话渗透率，而人均二氧化碳排放量和液体燃料消耗的二氧化碳排放量则被用作环境退化的替代指标。研究结果如下：第一，从非交互式回归来看，ICT（即移动的电话和互联网）对CO2排放量的影响并不显著。第二，通过交互回归，增加信通技术对人均二氧化碳排放量有积极的净影响，而增加移动的电话普及率本身对液体燃料消费的二氧化碳排放量有净负面影响。计算和讨论了信息和通信技术可以将净效应从正面变为负面的政策阈值。这些政策阈值是信通技术对二氧化碳排放产生负面影响所需的最低信通技术水平。政策和理论的其他实际影响进行了讨论。
This study examines how increasing ICT penetration in sub-Saharan Africa (SSA) can contribute towards environmental sustainability by decreasing CO2 emissions. The empirical evidence is based the Generalised Method of Moments and forty-four countries for the period 2000-2012. ICT is measured with internet penetration and mobile phone penetration while CO2 emissions per capita and CO2 emissions from liquid fuel consumption are used as proxies for environmental degradation. The following findings are established: First, from the non interactive regressions, ICT (i.e. mobile phones and the internet) does not significantly affect CO2 emissions. Second, with interactive regressions, increasing ICT has a positive net effect on CO2 emissions per capita while increasing mobile phone penetration alone has a net negative effect on CO2 emissions from liquid fuel consumption. Policy thresholds at which ICT can change the net effects from positive to negative are computed and discussed. These policy thresholds are the minimum levels of ICT required, for the effect of ICT on CO2 emissions to be negative. Other practical implications for policy and theory are discussed.
