Abstract

This paper aims at analysing the state of the Digital Economy by observing growth patterns of some Developmental Variables (GDP and GDP Per capita) and some digitisation variables. We have analysed with the help of growth models, correlation and Granger Causality amongst Developing, Developed and the World Economy during a period of recent 15 years.

There are five main findings. First, the existence of strong network economies between the broadband and the mobile technologies in developed world. Second, a general decline in fixed line services amongst all three-country grouping, which is not surprising. Third, economic growth variables and growth in mobile services are integrally linked. Fourth, there is bi-way causality between some growth variables and digitisation variables. Finally, there is evidence of a digital divide because digital economy at the global is dominated by developed economies, especially in E-commerce, which is a massive chunk of the global economy.

摘要

本文旨在通过观察一些发展变量（GDP和人均GDP）和一些数字化变量的增长模式来分析数字经济的状况。在最近的15年中，我们借助增长模型，发展中，发达经济体和世界经济之间的相关性和格兰杰因果关系进行了分析。

有五个主要发现。首先，在发达国家，宽带和移动技术之间存在强大的网络经济。其次，在所有三个国家的分组中，固定电话服务普遍下降，这不足为奇。第三，经济增长变量和移动服务增长是紧密联系在一起的。第四，一些增长变量与数字化变量之间存在双向因果关系。最后，有数字鸿沟的证据，因为全球的数字经济主要由发达经济体主导，尤其是在电子商务中，电子商务在全球经济中占很大比重。
