本研究考察了信息通信技术（ICT）对新兴经济体电力消费的影响。从动态面板需求模型获得的实证结果显示，当使用互联网连接、移动电话或个人电脑数量来衡量ICT时，ICT与用电量之间存在正相关且统计显著的关系。ICT的长期弹性小于收入弹性，但由于ICT的增长率远远高于收入增长率，因此ICT对电力需求的影响大于收入对电力需求的影响。这些结果的一个含义是，旨在通过在发展中国家增加对信息通信技术的采用来缩小发达经济体和发展中经济体之间“数字鸿沟”的政策与旨在减少温室气体排放的能源政策是不一致的。(C) 2012 Elsevier Ltd.版权所有。
This study examines the impact of information communication technology (ICT) on electricity consumption in emerging economies. The empirical results, obtained from dynamic panel demand models, show a positive and statistically significant relationship between ICT and electricity consumption when ICT is measured using internet connections, mobile phones or the number of PCs. Long-run ICT elasticities are smaller than income elasticities but because ICT growth rates are so much higher than income growth rates, the impact of ICT on electricity demand is greater than the impact of income on electricity demand. One implication of these results is that policies designed to close the "digital divide" between developed and developing economics by increasing the adoption of ICT in developing countries are put at odds with energy policies to reduce GHG emissions.
