McKinsey research into the Internet economies of the G-8 nations as well as Brazil, China, India, South Korea, and Sweden found that the web accounted for a significant and growing portion of global GDP. If measured as a sector, Internet-related consumption and expenditure were bigger than agriculture or energy. On average, the Internet contributed 3.4 percent to GDP in the 13 countries covered by the research—an amount the size of Spain or Canada in terms of GDP, and growing at a faster rate than that of Brazil.
"Research prepared by the McKinsey Global Institute and McKinsey's Technology, Media and Telecommunications Practices as part of a knowledge partnership with the e-G8 Forum, offers the first quantitative assessment of the impact of the Internet on GDP and growth, while also considering the most relevant tools governments and businesses can use to get the most benefit from the digital transformation. To assess the Internet's contribution to the global economy, the report analyzes two primary sources of value: consumption and supply. The report draws on a macroeconomic approach used in national accounts to calculate the contribution of GDP; a statistical econometric approach; and a microeconomic approach, analyzing the results of a survey of 4,800 small and medium-size enterprises in a number of different countries.
"The Internet's impact on global growth is rising rapidly. The Internet accounted for 21 percent of GDP growth over the last five years among the developed countries MGI studied, a sharp acceleration from the 10 percent contribution over 15 years. Most of the economic value created by the Internet falls outside of the technology sector, with 75 percent of the benefits captured by companies in more traditional industries. The Internet is also a catalyst for job creation. Among 4,800 small and medium-size enterprises surveyed, the Internet created 2.6 jobs for each lost to technology-related efficiencies.
"The United States is the largest player in the global Internet supply ecosystem, capturing more than 30 percent of global Internet revenues and more than 40 percent of net income. It is also the country with the most balanced structure within the global ecosystem among the 13 countries studied, garnering relatively equal contributions from hardware, software and services, and telecommunications. The United Kingdom and Sweden are changing the game, in part driven by the importance and the performance of their telecom operators. India and China are strengthening their position in the global Internet ecosystem rapidly with growth rates of more than 20 percent. France, Canada, and Germany have an opportunity to leverage their strong Internet usage to increase their presence in the supply ecosystem. Other Asian countries are rapidly accelerating their influence on the Internet economy at faster rates than Japan. Brazil, Russia and Italy are in the early stages of Internet supply. They have strong potential for growth" (http://www.mckinsey.com/Insights/MGI/Research/Technology_and_Innovation/Internet_matters, accessed 01-19-2012).
