Mobile telecommunications and the impact on economic development
基于192个国家1990-2007年数据，发现移动通信对经济增长的贡献在低收入国家为0.11%，高收入国家为0.20%，并建议推行自由化政策以促进移动普及。
Using annual data from 192 countries over the period 1990–2007, we assess the impact of mobile telecommunications on economic growth. We find that this impact is smaller for countries with a low mobile penetration, usually low income countries. While in low income countries the mobile telecommunications contribution to annual GDP growth is 0.11%, for high income countries this is 0.20%. The increasing returns from mobile adoption are also emerging when assessing the impact on productivity growth. To promote mobile telecommunications penetration liberalization policies along with appropriate regulatory frameworks are recommended. Such policies should be pursued more forcefully in cases where serious shortcomings exist.— Harald Gruber and Pantelis Koutroumpis
