Abstract We address the question: which countries-rich (high-income countries) or poor (middle-income and low-income countries) - tend to gain more from the Information and Communication Technology (ICT) revolution? By employing a panel of 123 countries consisting of 45 high-income countries, 58 middle-income countries, and 20 low-income countries from 2002 to 2017 and by constructing ICT index from mobile, internet, and fixed broadband, we find that in general ICT increases economic growth in both countries, however, poor countries tend to gain more from the ICT revolution.

信息通信技术对经济增长的影响——富国与穷国的比较

摘要 我们解决的问题是：哪些国家是富裕国家（高收入国家）或贫穷国家（中等收入和低收入国家）——倾向于从信息和通信技术 (ICT) 革命中获益更多？通过使用 2002-2017 年由 45 个高收入国家、58 个中等收入国家和 20 个低收入国家组成的 123 个国家的面板，通过构建移动、互联网和固定宽带的 ICT 指数，我们发现总体而言信息通信技术促进了两国的经济增长，然而，穷国往往从信息通信技术革命中获益更多。
